Abstract:
Growth chamber experiments were conducted to investigate the effect of size of fertilizer reaction zone, rate of added zinc and method of placement of added zinc on the dry matter yield, zinc concentration and zinc uptake of blackbeans grown on a calcareous soil. Relationships between zinc concentrations in the plant, zinc utilization by the plant and zinc concentration in the soil reaction zone were obtained. An equation was developed relating zinc utilization to zinc concentration in the fertilizer band, and a figure was derived showing how increasing the size of the fertilizer zone impacts upon the zinc concentration of the plant. The results indicate that inorganic zinc fertilizers must be mixed as uniformly as possible for maximum effectiveness. Key words: Zinc, placement, calcareous, soil, blackbean, Phaseolis vulgaris

Abstract:
Parsley is a biennial plant from the Apiaceae family that is used in the food, pharmaceutical, perfume and cosmetic industries. This plant has various mineral such as Fe and vitamins including A, B and C and grown in most parts of the world. Nano-fertilizers are a good alternative to sulfated fertilizers due to their higher solubility and gradual release of particles than conventional fertilizers. In order to investigate the effect of foliar application zinc on growth and yield of parsley, an experiment based on randomized complete blocks with 6 treatments and three replications was performed in the experimental field of Imam Khomeini Higher Agricultural Education Center. Treatments included foliar application of Nano zinc chelate fertilizer (0.5, 1 and 1.5 g/L) and zinc sulfate (1 and 1.5 g/L). The foliar application was performed in 4 to 6 leaf stage and repeated every 14 days till before harvesting. Number of leaves, plant height, leaf area, leaf length and width, fresh and dry weight of leaves and stems were measured. The results showed that the highest amount of the mentioned traits was obtained in the foliar application of 1.5 g/L Nano zinc chelate fertilizer and the lowest values were obtained at the control treatment. It is noteworthy that there is no significant difference between 1 and 1.5 g/L Nano zinc chelate fertilizer in terms fresh and dry weight of leaves and stems and both treatments are statistically in the same group. Therefore, foliar application of 1 g/L Nano zinc chelate fertilizer is economically recommended.

Abstract:
In order to study the effects of bio fertilizers and zinc fertilizer on antioxidant enzymes activity, chlorophyll content, soluble sugars and proline in triticale under salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications under greenhouse condition. Experiment factors were included salinity in four levels [no-salt (control or S0), salinity 20 (S1), 40 (S2) and 60 (S3) mM NaCl) equivalent of 1.85, 3.7 and 5.55 dS m−1 respectively], four bio fertilizers levels (no bio fertilizer (F0), application of mycorrhiza (F1), PGPR (F2), both application PGPR and mycorrhiza (F3) and three nano zinc oxide levels (without nano zinc oxide as control (Zn0), application of 0.4 (Zn1) and 0.8 (Zn2) g lit-1). Results showed that salinity severe stress (60 mM) decreased chlorophyll a, chlorophyll b, total chlorophyll, carotenoid and grain yield of triticale, whereas soluble sugars and proline content, the activities of Catalase (CAT), Peroxidase (POD) Polyphenol Oxidase (PPO) enzymes increased. Results showed that both application of bio fertilizer and 0.8 g lit-1 nano zinc oxide (F3Zn2) increased about 39% from grain yield in comparison with F0Zn0 under the highest salinity level. Based on the results, it was concluded that bio fertilizers and nano zinc oxide application can be recommended for profitable triticale production under salinity condition.

Abstract:
The aim of the research is to study the intensity of heavy metals accumulation in milk thistle leaf mass under fertilization with the latest types of fertilizers and to assess the environmental safety of such raw materials. Two experiments were laid in the research: the effect of fertilizing milk thistle with organo-mineral fertilizer Growth-concentrate on the intensity heavy metals accumulation by its leaf mass; the effect of fertilizing milk thistle with chelated fertilizers Phosphorus-chelate and Potassium-chelate on the intensity on heavy metals accumulation by the leaf mass. The use of a chelated Phosphorus chelate fertilizer for the fertilization of milk thistle crops leads to a 1.1 times decrease in the contamination of its leaf mass with cadmium and copper in comparison with the option without fertilizing its crops, and the increase in the concentration of lead and zinc compared to the control is insignificant and is within the range errors of experience. The use of fertilization of crops of milk thistle chelated fertilizer Potassium-chelate helps to reduce the contamination of its leaf mass with cadmium compared to the control, and the change in its contamination with copper is within the margin of error. At the same time, replacing the Growth-concentrate fertilizer with Phosphorus-chelate or Potassium-chelate when fertilizing milk thistle crops will lead to a decrease in the contamination of its leaf mass with lead, cadmium and copper, but will increase the contamination with zinc, compared to the control. The most environmentally safe leaf raw material of milk thistle in terms of lead, cadmium and copper content will be observed when fertilizing its crops with chelated fertilizers Phosphorus-chelate, and in terms of zinc content – when fertilizing with organo-mineral fertilizer Growth-concentrate. It is advisable to use Phosphorus-chelate fertilizer for the plant fertilization to reduce the contamination of the leaf mass of the medicinal raw material of milk thistle with heavy metals, in particular cadmium – by 9 % and copper – by 11 %,. To reduce contamination of the leaf mass with zinc by 81 %, it is recommended to use the organic-mineral fertilizer Growth-concentrate.

Abstract:
Nano-fertilizers are new generation of the synthetic<em> </em>fertilizers which contain readily available nutrients in nano scale range. Nano fertilizers are preferred largely due to their efficiency and environment friendly nature compared to conventional<em> </em>chemical<em> </em>fertilizers. To evaluate the effects of foliar spray<em> </em>of micronutrient nano-fertilizer (iron and zinc) and nano-titanium dioxide (nTiO<sub>2</sub>) solution on grain yield and its components in barley under supplemental<em> </em>irrigation conditions, a field experiment was carried out in the semi-arid highland region of Maragheh, Iran. Barley plants were separately treated with of chelated nano-scale zinc oxide (ZnO) and ferric oxide (Fe<sub>2</sub>O<sub>3</sub>) suspensions during tillering stage, booting and milky stages. Results revealed that days to<em> </em>anthesis and maturity significantly increased after application of both nano-fertilizers. Furthermore<em>,</em> a considerable improvement was observed in grain mass, spike length, number of the grains per spike, chlorophyll content, grain yield and harvest index by application of nano-fertilizer. However the impact of nano zinc fertilizer was more prominent than iron. Foliar application of nTiO<sub>2</sub> positively affected some morphophysiological characteristics like as days to<em> </em>anthesis, chlorophyll content and straw yield. The results suggest that the delivery of Zn into barley seedling through spray of nano-fertilizer can be an efficient nutrient management strategy in semi-arid regions. Overall, our result indicated that the integration of nanotechnology in fertilizer products can improve fertilizer use efficiency and significantly increase of barley yield. However, plant response to nanoparticles significantly depend on concentration and time of application as well as size, shape, and surface functionalization of the particles.

Abstract:
Rice is the major food crop grown on black soils of southern India and these soils have problems of high zinc fixation due to high clay content, high pH and dominance of smectite minerals causing zinc deficiency problems. The addition of zinc fertilizers to these soils has often been ineffective as the element is transformed to unavailable forms particularly under flooded rice conditions. Studies on the distribution of fertilizer zinc among different pools of soil zinc (Viets, 1962) could be useful in formulating methods of zinc application for higher efficiency of utilization. An attempt was therefore made to study the transformations of added zinc in soils in field experiments conducted in a rice-rice sequence involving the use of 65Zn as a tracer.

Abstract:
To compare the effects of various zinc (Zn) foliar fertilizers on correcting citrus Zn deficiency and to explore an effective correcting method, three common Zn fertilizers, Zn sulfate heptahydrate (ZnSO4.7H2O), Zn chloride (ZnCl2), and Zn nitrate hexahydrate [Zn(NO3)2.6H2O], were selected to spray the Zn-deficient citrus leaves, tested at different concentrations, with or without organosilicone surfactant. Zn content, chlorophyll levels, and photosynthesis characteristics of leaves were analyzed. Leaf Zn content was significantly increased with increase of the sprayed Zn concentration of the three Zn fertilizers. However, when the sprayed Zn concentration of ZnSO4.7H2O exceeded 200 mg·L−1, and Zn concentration of ZnCl2 or Zn(NO3)2.6H2O exceeded 100 mg·L−1, obvious necrotic spots formed on leaves. This necrosis disappeared when 0.025% organosilicone was added to the three Zn fertilizer solutions, even at a Zn concentration of 250 mg·L−1. Meanwhile, the Zn contents of leaves increased one to four times for these treatments. Furthermore, foliar application of the three Zn fertilizers significantly improved chlorophyll levels and photosynthetic capacity of Zn-deficient leaves. The data of chlorophyll and photosynthesis characteristics indicate that the correcting effect of ZnCl2 and Zn(NO3)2.6H2O is better than that of ZnSO4.7H2O, and could be further improved via supplement of organosilicone. In conclusion, ZnCl2 or Zn(NO3)2.6H2O containing 250 mg·L−1 of Zn and supplemented with 0.025% organosilicone is a safe and effective formulation of Zn foliar fertilizer for correcting citrus Zn deficiency.

Abstract:
After reviewing the literature on factors influencing zinc availability in soils, it was decided to investigate further aspects of the well documented zinc/phosphate interaction for the soil/maize system and to study the migration and transformations of inorganic and organic (sludge) fertilizer zinc in soils. A conventional pot experiment with maize to look at zinc/phosphate interaction, with thorough mixing of added fertilizer, indicated that phosphate could alleviate zinc toxicity effects, but did not show whether this was a soil or plant effect. A subsequent experiment in which soils treated with zinc and phosphate fertilizers were spatially separated by nylon net provided evidence that the interaction occurred, at least in part, in plant roots. This suggests limited benefit in the field for separate placement. Under field conditions, it is unrealistic to expect the same degree of soil mixing as used in typical pot experiments. Therefore an experiment with 65Zn was used to study the vertical movement of surface-applied inorganic zinc fertilizer. The same experiment was also used to study the changes in distribution of added zinc between a range of soil fractions (exchangeable, organic, manganese oxide, iron oxide and residual) at three soil pH values. Uptake was higher at lower pH, corresponding to greater amounts of zinc being retained on exchange sites. However, much of the added zinc was found in the manganese oxide fraction especially at higher pH. Zinc mobility during the experiment was almost negligible. Subsequently the soils left at the end of this experiment were incubated for 6 months and then used for a further pot experiment, to gain insight into residual zinc fertilizer effects. This showed a reduction in exchangeable zinc and plant uptake, with increases in zinc associated with organic matter and iron oxides.

Abstract:
Heavy metal contamination in food is a worldwide concern. Man-made ponds are domestic sites in the production of Procambarus clarkii and Procambarus zonangulus, two edible species of crayfish. Ponds may be constructed in former sugar cane or rice fields. Crayfish farming is an ancillary seasonal business within the rice-growing season. The use of products to control insects, pests, and weeds in rice and sugar cane production, may cause an accumulation of heavy metals in the crayfish tail within pond structures. Arsenic, cadmium, copper, and zinc are heavy metals that are absorbed through the roots of and distributed through rice products. Metabolites associated with rice products are absorbed in the human body. Research suggests that metabolites associated with heavy metals cause disease in animals and humans.

Abstract:
In order to investigate the effect of foliar application of organic fertilizer and micronutrients on quantitative and qualitative characteristics of Niger plant, a field experiment was conducted in a complete randomized block design with three replications at Shahrekord University Research Farm during the years 2013-2014. Treatments included three levels of humic acid (1, 3, and 6 liters of humic acid per hectare), iron (4 parts per million, ppm), zinc (4 parts per million, ppm) and control (without humic acid iron, and zinc). In this experiment, traits of the number of heads per plant, seeds number per head, 1000 seeds' weight, grain yield, and also oil and protein content were evaluated. The findings showed that foliar application of humic acid, zinc and iron resulted in a significant increase in all analyzed traits. The most significant plant response was obtained with the use of 6 liters humic acid per hectare, and the second most significant plant response was seen with the sprayed zinc treatment which was probably due to limited absorption and deficiency of these elements in the tested soil.

Abstract:
The effects of poultry manure versus inorganic fertilizer use on copper, zinc and manganese concentrations and the sustainability of metal contents under raspberry cultivation was investigated on two aeolian soils in the Lower Fraser Valley, British Columbia. Total elemental analysis by a teflon bomb procedure using reverse aqua regia and hydrofluoric acid was done on soils sampled at three depths (0-15 cm, 15-30 cm and +40 cm) and results were compared to metal contents extracted by the Mehlich III method. High variability of some of the soil data was attributed to mixing of the loess capping with the underlying glacio-fluvial outwash material, differences in site conditions of the test fields, variations in sampling depth, and inadequate analytical reproducibility at the low concentrations found in some of the soils. For the variables tested, differences between sites most often occurred in the first 30 cm and never at the +40 cm depth. Higher contents in the 0-30 cm depth than in the lower depths indicated an enrichment of the surface layers either by anthropogenic inputs or by bioaccumulation. Poultry manure applications had a significant effect on organic matter content, total and available manganese, and total and available zinc in both soils studied. The comparison of the manured versus the inorganically fertilized site indicated that zinc was the metal most effected by the manure application. The other metals were not significantly increased by poultry manure amendments. The comparison of the site that had been under long-term raspberry cultivation against the site that had been only recently converted to raspberries from long-term pasture cover, showed that long-term raspberry cultivation reduced metal and organic matter contents in the 0-15 cm depth and increased these variables in the 15-30 cm depth. It was hypothesised that this was in direct response to differing biocycling patterns under different land uses. Total and available manganese and zinc were strongly interconnected and their correlation to the organic matter content appeared most interesting in terms of fluxes between the various soil components. inorganically fertilized site indicated that zinc was the metal most effected by the manure application.

The determination of the appropriate levels of fertilization with micronutrients is essential for the culture to express its full productive potential, since they participate in vital functions in the metabolism of plants, participating in compounds responsible for metabolic and / or phenological processes. This research aims to evaluate the response of sugarcane (Saccharum officinalis) to fertilization with micronutrients (boron and zinc) in low fertility soils, in order to establish their adequate nutritional content. The experimental design was randomized blocks, in a factorial scheme (3 x 4) considering the application of three doses of boric acid (17% B) to provide 0, 1.0 and 2.0 kg ha-1 of boron and four doses Of zinc sulfate (20% Zn) for the supply of 2.0; 4.0 and 6.0 kg.ha-1 of zinc. The experimental area consisted, therefore, of three blocks with twelve experimental units, totaling 36 plots. In order to verify the results, the nutritional status of the plant (foliar diagnosis), soil analysis, indicators of technological quality and sugarcane production were analyzed. Through the evaluation of the results of the micronutrient contents foliar and in the soil it is noticed that there was no direct relation between the leaf contents of the sugarcane culture and different treatments applied during the conduction of the experiment. The technological attributes (Fibra, Brix, Pol and ATR) were not significantly influenced by the fertilization with boron and zinc. In cane-plant the highest yields were reached by application of 2.0 kg ha-1 of zinc represented by treatment 2, and in treatment 10, with a respective increase of 6% and 10%.
A determinação dos teores adequados de adubação com micronutrientes é fundamental para que a cultura possa expressar todo seu potencial produtivo, já que participam de funções vitais no metabolismo das plantas, participando de compostos responsáveis por processos metabólicos e/ou fenológicos. Esta pesquisa tem como objetivo avaliar a resposta da cana-de-açúcar (Saccharum officinalis) à adubação com micronutrientes (boro e zinco) em solos de baixa fertilidade, buscando estabelecer seus teores nutricionais adequados. O delineamento experimental foi blocos ao acaso, em esquema fatorial (3 x 4) considerando a aplicação de três doses de ácido bórico (17% B) visando fornecer 0, 1,0 e 2,0 kg ha-1 de boro e quatro doses de sulfato de zinco (20% Zn) para o fornecimento de 2,0; 4,0 e 6,0 kg.ha-1 de zinco. A área experimental constava, portanto, de três blocos com doze unidades experimentais, totalizando 36 parcelas. Para a verificação dos resultados foi analisado o estado nutricional da planta (diagnose foliar), a análises de solo, os indicadores de qualidade tecnológica e de produção da cana-de-açúcar. Através da avaliação dos resultados dos teores de micronutriente foliares e no solo nota-se que não houve relação direta entre os teores foliares da cultura da cana-de-açúcar e diferentes tratamentos aplicados durante a condução do experimento. Os atributos tecnológicos (Fibra, Brix, Pol e ATR) não foram influenciados significativamente pela adubação com boro e zinco. Em cana-planta as maiores produtividades foram atingidas pela aplicação de 2,0 kg ha-1 de zinco representado pelo tratamento 2, e no tratamento 10, com aumento respectivo de 6% e 10%.

A pesquisa foi instalada em uma área experimental (latitude 6º54’59,88”S, longitude 35º09’17,86”O e altitude de 121,00 m) da Fazenda Capim II, localizada no Município de Capim/PB, com objetivo de se avaliar a cultura da cana-de-açúcar (Saccharum spp), variedade SP 79 1011, submetida a dois fatores: lâminas de água de irrigação e níveis de adubação com zinco. O delineamento experimental consistiu em blocos casualizados (DBC), com três repetições em esquema fatorial 5 x 5 analisados conjuntamente. As lâminas de irrigação foram: sequeiro, 25% da ETc (256,64 mm), 50% da ETc (513,29 mm), 75% da ETc (769,93 mm) e 100% da ETc (1026,57 mm) com as respectivas precipitações efetivas 780,06, 713,31, 487,54, 243,71 e 194,51 mm. Os níveis de zinco foram 0, 1, 2, 3 e 4 kg ha-1. O equipamento de irrigação utilizado na pesquisa foi do tipo pivô central fixo. O turno de irrigação, definido em função da análise físico-hídrica do solo, foi de nove dias utilizando 100% da água do solo. A ETo foi definida através do tanque “classe A” e a ETc foi determinada em função da idade da planta e de seu respectivo Kc. Abateu-se, do cálculo da lâmina de irrigação, a precipitação efetiva dentro do turno de irrigação. Foram determinadas as funções de resposta, em termos de crescimento e desenvolvimento fisiológico, bem como em termos econômicos, definindo-se, para tanto, os níveis dos dois fatores que proporcionam os melhores resultados econômicos. Até os sete meses de idade, a queda média de 50% no perfilhamento ocorreu independentemente dos fatores estudados ocorrendo diferenças significativas ao final do ano de cultivo. A resposta fisiológica aos fatores estudados foi significativa em altura, índice de área foliar, fitomassa total, fitomassa das folhas e fitomassa dos colmos. Do ponto de vista da qualidade da matéria-prima, o rendimento mínimo em açúcares totais recuperáveis foi de 96,57 kg t-1 e o máximo foi de 153,55 kg t-1. A cultura respondeu a lâmina de água de irrigação, em termos de produtividade, de forma significativamente diferente, sendo a mínima de 28,33 t ha-1 e a máxima de 106,47 t ha-1. Em termos de eficiência no uso da água pela cultura, o valor mínimo foi de 3,63 kg m3 e o máximo de 8,71 kg m3. Do ponto de vista econômico, foi calculado um modelo de função de resposta P(L,Zn) = a +b*L+c*L²+d*Zn+e*Zn²+f*LZn para estimar, diante do efeito conjunto dos dois fatores, qual combinação (L, Zn) resultaria em maiores produtividades (Lm, Znm) e maiores lucros brutos (L*,Zn*). De acordo com a tendência do modelo, a combinação que maximizou a produtividade em 181,26 t ha-1 foi (1.947,82 mm de lâmina total com 3,94 kg ha-1 de zinco) propiciando um lucro bruto de R$ 16,57 t-1. Ainda segundo o modelo, a combinação que maximiza o lucro bruto em R$ 21,06 t-1 é 1.628,06 mm com 1,80 kg ha-1 para uma produtividade de 168,59 t ha-1. Entretanto, a adoção da lâmina que maximiza o lucro bruto implica um volume de água maior que aquele aplicado à cultura, quando irrigada com 100% da ETc (1.221,08 mm). A cana de sequeiro conferiu ao produtor um prejuízo de R$ -1,43 t-1, independentemente da combinação. Quando foram aplicados 25% da ETc, o prejuízo foi maior, da ordem de R$ -9,64 t-1 em detrimento da combinação estudada. A combinação L50, Zn3 proporcionou um LB de R$ 5,86 t-1; para L75, Zn3 o LB foi de R$ 7,17 t-1. A combinação que conferiu o maior LB (R$ 19,60 t-1), com uma produtividade de 101,05 t ha-1, foi 1.221,08 mm de lâmina total e 3,0 kg de Zn ha-1 (L100, Zn3).
The research was conducted in an experimental area (coordinates 6º54’59,88”S; 35º09’17,86”W and 121,00m of altitude) of the Capim II Farm in the municipality of Capim/PB with the objective to evaluate the response of sugarcane crop (Saccharum spp.) variety SP 79 1011, submitted to different depths of irrigation water and fertilization levels with zinc to obtain their response functions for the growth and physiologic development, as well in economical terms. . The experimental design consisted of randomizered blocks, with three repetitions in 5 x 5 factorial scheme analyzed jointly. The irrigation depths were cultivation without irrigation, 25% of ETc (256,64 mm), 50% of ETc (513,29 mm), 75% of ETc (769,93 mm) e 100% of ETc (1.026,57 mm) with the respective effective precipitations of 780,06, 713,31, 487,54, 243,71 and 194,51 mm and the levels of zinc were 0, 1, 2, 3 and 4 kg ha-1. The irrigation equipment used in this research was a fixed central pivot . The irrigation frequency was defined in function of physical properties of soil and frequency of irrigation was of nine days using 100% of soil moisture. ETo was defined through the tank Class “A” and ETc was calculated in function of the plant age and respective Kc. The effective precipitation during the interval of irrigation was substracted from the calculation of depth of irrigation to be applied.. Until the seven months of age the mean reduction of 50% in number of plants occurred independently of the factors studied presenting significant differences at the end after one year of cultivation. The physiologic response to the studied factors, at the end of the year was significant, in plant height, leaf area index, total dry mass, dry mass of leaves and dry mass of stems. The point of view quality of the raw material. the minimum yield in recoverable total sugars (RTS) was of 96,57 kg t-1 and the maximum was of 153,55 kg t-1. The crop responded in terms of production significantly where the minimum was of 28,33 t ha-1 and the maximum was of 101,05 t ha-1. In terms of EUW (efficiency use water) for the crop, the minimum value was of 3,63 kg m-3 and the maximum was of 8,71 kg m-3. From the economical point of view, a model response function was calculations (P(L,Zn) = a+b*L+c*L²+d*Zn+e*Zn²+f*LZn) to estimate the combined effect of two factors, with combination (L, Zn) it would result in larger productivities (Lm, Znm) and larger gross profit (L*,Zn*). It was Verified that in agreement with the tendency of the model, the combination that had maximized the productivity of 181,26 t ha-1 , was 1.947,82 mm with 3,94 kg ha-1 of zinc, resulting in a gross profit (GP) of R$ 16,57 t-1. However, the same model estimated that the combination which maximizes the GP of R$ 21,06 t-1, consisted of 1.628,06 mm water with 1,80 kg ha-1 of zinc, for a productivity of 168,59 t ha-1. However, the adoption of irrigation depth that maximizes GP implicates in a larger volume of water compared to that applied to the crop when irrigated with 100% of the ETc (1.221,08 mm). the sugar cane without irrigation (control) resulted in a loss of R$ -1,43t-1 to producer, independently of the combination. When irrigation was applied equivalent to 25% of the ETc the loss was more, of the order of R$ 9,64 t-1 independently of studied combination. The combination (L50, Zn3) provided a GP of R$ 5,86 t-1. For L75, Zn3 GP was of R$ 7,17 t-1. The combination that provided highest GP (R$ 19,60 t-1) with a productivity of 101,05 t ha-1 was 1.221,08 mm with 3,0 kg ha-1 (L100, Zn3).

Abstract:
Sewage sludge is the product from wastewater treatment that mostly is considered as a waste material. However, it contains several nutrients, especially phosphorus, potassium and nitrogen which are excellent fertilizers. The downside is the harmful content it also carries with pathogens, heavy metals and a variety of organic pollutants that in many cases have unknown effects on the ecosystem. A possible solution to this problem could be to pyrolyse the sewage sludge and by that decrease the levels of heavy metals and also render both pathogens and organic pollutants harmless. In this thesis project pyrolysis of dried sewage sludge has been evaluated at temperatures 650 750, 850 and 950 °C with addition of chlorine in the form of PVC and straw. An energy balance for pyrolysis and drying of dewatered sewage sludge has also been suggested. The results of the pyrolysis evaluation indicate that cadmium concentration can be reduced significantly with increasing temperature in the product char. But also other heavy metals like lead and zinc are affected at the higher temperatures evaluated. Mercury is completely removed from the char residue. The more latent volatile metals copper, chromium and nickel cannot be reduced to lower concentrations at these temperatures. They are instead enriched under these conditions. Chlorine addition to the sludge enhances the evaporation of all heavy metals but copper, nickel and chromium. The energy balance over the system indicates that the drying process requires more energy than is released from the sludge into the pyrolysis gases. The energy carried by the pyrolysis gases is however larger than what is required to drive the pyrolysis process.

Abstract:
Philosophiae Doctor - PhD
Cape Town includes two vegetable farming areas within the city limits, the Joostenbergvlakte/Kraaifontein area and the Philippi area. Both areas supply produce to local markets and further afield. Sporadically, high levels of cadmium, copper, lead and zinc have been found to occur in some of the soils, irrigation water resources and crops. To find the sources of specifically Cd, Pb and Zn to these agricultural systems, extensive analysis of several heavy metals in inputs such as fertilizers, agrochemicals and supplementary water resources to these farming areas was undertaken. Heavy metal concentrations in soils, irrigation water resources and crops were also determined. Two mitigation techniques that could be used to remediate Cd, Pb and Zn contamination were investigated. The first mitigation method included immobilization of heavy metals as phosphate complexes by using a triple super phosphate fertilizer, while the second method involved mobilisation and thus leaching of heavy metals away from plant roots using EDTA. These mitigation methods were tested in a pot experiment using cabbage as the experimental crop and soil from these areas as growth medium. A survey of common farming practices in these two areas and farmers willingness to use remediation methods was conducted.

Abstract:
AbstractThe global rise in human population has led to the intensification of agricultural activities to meet the ever-rising food demand. The potato (Solanum tuberosum L.) is a crop with the potential to tackle food security issues in developing countries due to its short growth cycle and high nutrient value. However, its cultivation is heavily dependent on artificial fertilizers for yield maximization which culminates in global warming and other environmental problems. There is need, therefore, for its alternative fertilization technologies to mitigate climate change. This study evaluated the potential of indigenous rhizobacteria for potato cropping in Tanzania. Ten potato rhizobacterial isolates belonging to Enterobacter, Klebsiella, Citrobacter, Serratia, and Enterobacter genera were obtained from a previous collection from different agro-ecological areas in Tanzania. The isolates were characterized culturally, microscopically, biochemically, and by their carbohydrate utilization patterns. Their in vitro plant growth-promoting (PGP) traits such as nitrogen fixation, solubilization of phosphates, potassium, and zinc, and production of siderophores, indole acetic acid, and gibberellic acids were then evaluated. Lastly, sterilized potato seed tubers were bacterized with the inoculants and grown in pots of sterile soil in a screen-house using untreated plants as a control experiment. The potato rhizobacterial isolates had varying characteristics and showed varying in vitro PGP activities. The screen-house experiment also showed that the rhizobacterial treatments significantly (p < 0.05) enhanced different parameters associated with potato growth by up to 91% and established the potential of most of the isolates as alternative biofertilizers in potato cropping systems in Tanzania.

Abstract:
The widespread practices of viniculture (the study of production of grapes for wine) and oenology (the study of winemaking) affirm the generalization that grapevines have fewer problems with mineral deficiency than many other crops. Only occasionally is the addition of iron (Fe), phosphorus (P), magnesium (Mg), and manganese (Mn) supplements to the soil needed. Addition of potassium (K), zinc (Zn), and boron (B) to the soil is more common. And, of course, nitrogen (N) is critical for the production of proteins. Over the years, various transition metals (metals in groups three through twelve [3– 12] of the periodic table, Appendix 1) have been shown to be generally important. These groups include iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn), and copper (Cu). Many metals are bound to organic molecules that are important for life. Some of the metals, such as copper (Cu) and iron (Fe), are important in electron transport while others, including manganese (Mn) and iron (Fe), inhibit reactive oxygen (O) species (ROSs) that can destroy cells. Metals serve both to cause some reactions to speed up, called positive catalysis while caus¬ing others (e.g., unwanted oxidation) to slow down (negative catalysis). It is not uncommon to add nitrogen (N), in the form of ammonium salts such as ammonium nitrate (NH4NO3), as fertilizer to the soil in which the vines are growing. It is also common to increase the nitrogen (N) content in the soil by planting legumes (legumes have roots that are frequently colonized by nitrogen-fixing bacteria). Nitrogen- fixing bacteria convert atmospheric nitrogen (N2), which plants cannot use, to forms, such as ammonia (NH3) or its equivalent, capable of absorption by plants. Nitrogen, used in plant proteins, tends to remain in the soil after harvest or decomposition. With sufficient nitrogen present in the soil the growth cycle can begin again in the following season without adding too much fertilizer. In a more general sense, however, it is clear (as mentioned earlier) that the soil must be capable of good drainage so the sub-soil parts of the plant do not rot and it must be loose enough to permit oxygen to be available to the growing roots.

Abstract:
Micronutrients needed by plants are Cu, Fe, Mn, Zn, B, Mo, Cl, Ni, Co, V, Si, and Na. The required amounts of each of these elements is very small but still essential for desirable plant growth and reproduction. These elements must be applied to soils cautiously for the range between deficient and toxic is very small. It is unwise to use a fertilizer containing all of these micronutrients. Any one of them may already be high enough in soils to cause toxicity from that particular element. If a micronutrient is suspected of being deficient, it would be wise to get soil tests and plant tissue tests to corroborate your suspicions. If a micronutrient is deficient, one should apply only the amount recommended but no more. Sometimes a toxicity of an element is more difficult to correct than a deficiency. Copper, iron, manganese, cobalt, and zinc can be present in soils as (a) several types of precipitates, (b) adsorbed onto the surface of soil particles, (c) present in primary minerals (rocks) and secondary minerals (clays), and (d) present as complex ring compounds. These forms may or may not be available to plants. Precipitates of Cu, Fe, Mn, or Zn often form in soils at high pH (after liming Fig. 14.1). This may occur in soils near buildings from the lime used in the mortar. Soil acids dissolve the lime into Ca++ or Mg++ that migrate into the soil raising the pH and cause these micronutrients to precipitate. Often an Fe deficiency is evident, particularly on acid-loving plants, such as azaleas, rhododendrons, or hollies. If this is extensive, the soil near the buildings may need to be replaced. With limited areas, the soil can be acidified by adding elemental S near the plants affected. The elements Cu, Fe, Mn, and Zn can exist as soluble forms or precipitates, depending on the pH of the soil. The soluble forms as cations are present when soils have poor internal drainage (poorly drained soils), whereas the oxides of these elements are present where the soil is well aerated.

Abstract:
Chemical fertilizers are a quick way to increase nutrients in the soil, but their use is economically costly and dangerous for the environment. Plant Growth Promoting Bacteria (PGPB) are able to increase the bioavailability of fertilizers through biological nitrogen (N) fixation, as well as potassium (K), phosphorus (P), and zinc (Zn) solubilization. The enhanced amount of soluble macro- and microelements in the close proximity of soil-root interface increases the fertilizer use efficiency ~ by 20-40 %.

Abstract:
The influence of processing the serpentinite quarry from the Caucasian mountains at the foot of the Mount Elbrus crushed waste on soil agrochemical properties, phytotoxicity of spring barley, influence on barley plant biomass and its chemical composition were investigated. Ground and granular serpentinite had a different effect on soil and plants. Application of serpentinite fertilizers significantly increased the content of calcium, iron, 227.95-376.75 and 5.05-9.62 mg kg-1, total and plant-derived magnesium 0.34-0.52 and 1.19-2.16 mg kg-1, lead and nickel, while the amount of copper dropped substantially; the soil was becoming more alkaline. Application of ground serpentinite lead to alkalizing of the soil much more compared to the granular, with a significant increase in plant-derived magnesium. The influence of serpentinite increased the yield of spring barley plants in green and dry mass by 0.049-0.256 and 0.011-0.046 g or 0.65-3.41 and 1.19-2.59% out of the growing vessel, and dry matter increased by 0.12-0.26 % units, the yield of spring barley green and dry mass under the influence of ground serpentinite was higher than of granular serpentinite fertilizer, and the dry matter was found to be significantly higher than that of unfertilized spring barley plants. Ground and granular serpentinite was not phytotoxic to spring barley. An application of ground serpentinite increased an amount of calcium, potassium and magnesium in the barley dry matter compared to the granular serpentinite. Ground and granular serpentinite reduced the amount of trace elements copper and manganese in the dry mass of the plant, and the amount of zinc decreased only after fertilization with granular serpentinite. An application of serpentinite significantly decreased content of lead, chrome and cadmium while nickel content significantly increased in the dry matter of barley plants.

Full text
Abstract:
Municipal sludge, originating from two wastewater treatment plants in Sweden, has been burned together with wood pellets or bituminous coal in a circulating fluidised bed (CFB) boiler equipped with a secondary cyclone and bag filter for fly ash removal. Such co-combustion is an alternative to mono-combustion of sludge. The sludge is burned in either mechanically dewatered or pre-dried form. The mechanically dewatered sludge was fed with a pump, but pre-dried sludge could be fed by the fuel feed system normally used for coal. Both types of sludge were burned with either wood-pellets or coal as main fuel under identical operating conditions, typical for a CFB boiler. The focus was on ash balances and on analysis of fuels and ashes to obtain concentrations of relevant species. The presence of phosphorous (P) is of special interest in relation to trace elements, such as mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), copper (Cu), nickel (Ni) and zinc (Zn). For this reason a comparison has been made between these trace elements and phosphorous in the various ashes and the original sludge as well as other sources of phosphorous that could be used for agricultural purposes. The results show that sewage sludge and fly ash, after combustion of sludge, contain similar amounts of phosphorous as other phosphorous sources for agricultural use, but the levels of trace elements in relation to phosphorous (Hg, Cd, Pb, Cr, Cu) are higher than in animal manure and artificial fertilizer and higher than the present limits in Sweden.

Abstract:
In a green house pot experiment, the effects of three amendments, sulphur (S), ammonium sulphate ((NH4)2SO4) and ethylenediaminetetracetic acid (EDTA) were tested for phytoextraction of Cd and Zn by rapeseed (Brassica napus L.). Elemental sulphur was applied as 20.00, 60.00, and 120.00 mg.kg−1 soil. EDTA was tested at a dose of 585.00 mg.kg−1 soil, and (NH4)2SO4) at a rate of 0.23 mg.kg−1 soil. All treatments received a base fertilization (Hogland) before sowing. Plants were harvested after 51 days of growth and shoot dry matter and soil samples were analysed for metal contents. All amendments caused a significant increase in Cd and Zn contents in plant shoots of all treatments than control treatment. Further, EDTA was most effective for extraction metals concentrations in shoot biomass but the plants showed significant signs of toxicity and yield were severely depressed. The addition of sulfur favorably influenced plant biomass production. The fertilized ammonium sulfate treatment resulted in the highest phytoextraction of Cd and Zn and the amounts of these metals accumulated in plant shoot exceeded by a factor of 4 and 3 respectively. Finally, Brassica napus could be used for soil remediation keeping its other uses which will make the contaminated site income generating source for the farmers.
