Abstract:

AbstractA bibliometric analysis of research articles published on water-use efficiency was performed using the Web of Science database and evaluated. Journal titles, publication years, subject categories, keywords and countries publishing were obtained. A number of 2077 papers were retrieved, two-thirds of them published in the last decade. The articles were published in 439 journals, with Agricultural Water Management, Agronomy Journal, Crop Science, Field Crops Research and Indian Journal of Agricultural Sciences the most productive. Most of the leading productive journals have Impact Factors in the top quartiles of the Journal Citation Reports. Agronomy, Plant Sciences, Water Resources and Agriculture Multidisciplinary were the most common journal subject categories, indicating a wide diversity of research fields ascribed to this topic. The predominant key words and phrases used were growth, ‘carbon isotope discrimination’, yield, photosynthesis, ‘gas exchange’, evapotranspiration and ‘stomatal conductance’. The productivity ranking for countries was headed by China (456 papers), followed by the USA (410), Australia (176) and India (165). A content analysis of the papers made identification of the key issues of greatest scientific concern possible, as well as their evolution over time. The most cited papers relate to physiological aspects, but also important studies on experimental biology, drought resistance, effects of climate, crop production and ecology, among others.

Abstract:

Firstly, I would like to say that it is a great honour to take over the position of Editor-in-chief of Experimental Agriculture, one of the most important journals devoted to publishing original and high quality papers addressing the many facets of agricultural sciences in subtropical and tropical areas. Tradition! I would say that this single word has an enormous meaning for me. I am proud in serving Experimental Agriculture, a journal published by the Cambridge University Press since 1933. Originally titled The Empire Journal of Experimental Agriculture (1933-1964), the publication's mission was ambitious “every new fruit of discovery and invention in the agricultural field”, publishing critical information for improving agricultural systems. So pertinent was the Journal's remit that it was recognised in an article published in Nature in May 27th, 1933. Currently, Experimental Agriculture has an Impact Factor of 1.079 (ISI Thomson Reuters) and stands as a Q1 journal in ‘Agronomy and Crop Science’ (SCImago Journal and Country Rank). In 2015, we received submissions from the five continents, with the majority coming from Asia and Africa. Thank you for considering Experimental Agriculture as a potential journal to publish your paper!

Abstract:

AbstractAgricultural biotechnology has been largely opposed by advocates in the sustainable agriculture movement, despite claims by the technology's proponents that it holds the promise to deliver both production (economic) and environmental benefits, two legs of the sustainability stool. We argue in this paper that participants in this polarized debate are talking past each other because assumptions about biotechnology and sustainability remain simplistic and poorly defined. Genetically engineered (GE) herbicide-resistant and insect-resistant crop varieties are the most visible current forms of agricultural biotechnology, and thus the form of biotechnology that many in the sustainability movement react to. However, these crops represent a biotechnology option that has paid insufficient attention to the integrated and systemic requirements of sustainable agriculture. In particular, common definitions of sustainable agriculture reinforce the need to include consideration of socio-economic distributive or equity effects into any assessment of sustainability. However, the frameworks that have been proposed to assess the potential for GE crops to enhance sustainable agriculture generally neglect this essential socio-economic dimension. We present an analysis that augments the sustainability frameworks to include the full suite of environmental, economic and social impacts. A review of the latest science on each impact category reveals that crop biotechnology cannot be fully assessed with respect to fostering a more sustainable agriculture due to key gaps in evidence, especially for socio-economic distributive effects. While the first generation of GE crops generally has made progress in reducing agriculture's environmental footprint and improving adopting farmers' economic well-being, we conclude that these early products fall short of the technology's capacity to promote a more sustainable agriculture because of the failure of those developing and promoting the technology to fully engage all stakeholders and address salient equity issues. To realize the sustainability potential of biotechnology will require fundamental changes in the way public and private research and technology development and commercialization are structured and operated. We identify new approaches in these areas that could make this powerful biological science more compatible with sustainable agriculture.

Abstract:

To appraise the major research outputs of agronomic crops and cropping systems and to direct the future research priorities of Agronomy Department of post-graduate (PG) program of Institute of Agriculture and Animal Sciences (IAAS), a rigorous review was accomplished on about two decadal (2000-2018) student’s thesis research works. The review revealed that the agronomic researches at IAAS from 2000 to 2012 were concentrated mostly in on-station farm of Rampur, Chitwan and found their focus on 11 food grain crops with five major themes viz. varietal evaluation, crop management, soil nutrient and weeds management, and crop simulation modeling. With the shifting of IAAS PG program from Rampur to Kirtipur in 2013, the major agronomic researches were found to be concentrated in on-farm stations due to transitional movement of IAAS to Agriculture and Forestry University, Nepal. A total of 115 agronomic studies were conducted on various crops, of which 92 were on cereals, 8 on legumes, oilseed and minor cereals including potato. There were records of 10 studies on rice-wheat and 3 studies on maize-based systems. The huge gaps between the potential and farmers' field yield and between the potential and research station yields for rice, maize and wheat crops suggested a great scope to raise yields of cereals by improved agronomical researches on varieties evaluation, crop and nutrient management and weed management. Simulation modeling study predicted that the varieties of rice and maize adopted at present could sustain the yields only for recent few years and needed for introduction of new climate resilient varieties, then after. Innovative and new researches on eco-region suited on-farm trails with variety identification, improved crop husbandry and soil nutrient management, improved weed and water management and on agro-meteorology, conservation agriculture, climate change adaptation and crop simulation modeling are advised as future research frontiers to uplift the productivity and reduce yield gaps of major food crops and to strengthen the academics of post-graduate research in near future.

Abstract:

Global trends in human population and agriculture dictate that future calls made on the resources (physical, human, financial) and systems involved in producing food will be increasingly more demanding and complex. Both plant breeding and improved agronomy lift the potential yield of crops, a key component in progressing farm yield, so society can reasonably expect both agronomy as a science and agronomists as practitioners to contribute to the successful delivery of necessary change. By reflecting on current trends in agricultural production (diversification, intensification, integration, industrialisation, automation) and deconstructing a futuristic scenario of attempting agricultural production on Mars, it seems the skills agronomists will require involve not only the mandatory elements of their discipline but also additional skills that enable engagement with, even leadership of, teams who integrate (in sum or part) engineering, (agri-)business, economics and operational management, and build the social capital required to create and maintain a diverse array of enhanced and new ethical production systems and achieve increasing efficiencies within them.

Abstract:

SUMMARYThe principles that control effectiveness of rock phosphates as fertilizer are now fairly well understood so that the potential effect of a material can be predicted with some confidence from laboratory analysis of the raw material. Soil characteristics, especially acidity, and calcium and phosphate status, are important: if these are not conducive to dissolution, crop response to rock phosphate is small. Some crop characteristics, especially the extent of root systems and whether they are infected with mycorrhizae, also affect utilization of rock phosphate. Dissolution of rock phosphates may be too slow for rapidly growing crops but may be adequate for perennial crops.Such factors limit the use of rock phosphates for direct application, so that much greater knowledge of the characteristics of the phosphates, soils and crops, and their interactions, is necessary for their successful use than for the soluble phosphates. Economic considerations are important also. Because the phosphate content is less than that of concentrated soluble fertilizers, the cost of transporting rock phosphates, per unit of phosphorus, may not be economic. However, for acid and calcium deficient soils the larger amounts of calcium that rock phosphates supply may be an advantage and may lessen or eliminate the need for lime, especially for crops that require relatively large amounts of calcium.Fosfatos de roca en la agricultura

Abstract:

Agriculture is in crisis. Soil health is collapsing. Biodiversity faces the sixth mass extinction. Crop yields are plateauing. Against this crisis narrative swells a clarion call for Regenerative Agriculture. But what is Regenerative Agriculture, and why is it gaining such prominence? Which problems does it solve, and how? Here we address these questions from an agronomic perspective. The term Regenerative Agriculture has actually been in use for some time, but there has been a resurgence of interest over the past 5 years. It is supported from what are often considered opposite poles of the debate on agriculture and food. Regenerative Agriculture has been promoted strongly by civil society and NGOs as well as by many of the major multi-national food companies. Many practices promoted as regenerative, including crop residue retention, cover cropping and reduced tillage are central to the canon of ‘good agricultural practices’, while others are contested and at best niche (e.g. permaculture, holistic grazing). Worryingly, these practices are generally promoted with little regard to context. Practices most often encouraged (such as no tillage, no pesticides or no external nutrient inputs) are unlikely to lead to the benefits claimed in all places. We argue that the resurgence of interest in Regenerative Agriculture represents a re-framing of what have been considered to be two contrasting approaches to agricultural futures, namely agroecology and sustainable intensification, under the same banner. This is more likely to confuse than to clarify the public debate. More importantly, it draws attention away from more fundamental challenges. We conclude by providing guidance for research agronomists who want to engage with Regenerative Agriculture.

Abstract:

Companion crops are commomly seeded with alfalfa in the spring as an establishment method. The objectives of this research were to evaluate the performance of seedling Alfalfa (Medicago sativa L.) in terms of yield when grown with spring oats (Avena sativa) as a companion crop and to evaluate the amount of weed control in the alfalfa companion crop seeding, under various management practices. Six establishment treatments were imposed: (1) solo-seeded alfalfa raised according to standard procedures recommended for Kentucky, (2) solo-seeded alfalfa with a herbicide treatment, (3) alfalfa seeded with an oat companion crop and treated with a herbicide, (4) alfalfa seeded with an oat companion crop with harvest at 10cm to 21cm of height, (5) alfalfa seeded with an oat companion crop, oats removed for haylage, and (6) alfalfa seeded with an oat companion crop, allowing the oats to produce seed before harvest. In the first seeding year (1992) the alfalfa and oat companion crop that was treated with a grass herbicide had siginificantly higher yields than the check or alfalfa and oat companion crop that was allowed to produce seed. In the second seeding year (1993) there were no significant differences among the establishment methods. The second year of the 1992 seeding experiment had unexpected results. The alfalfa and oat companion crop treated with a grass herbicide had greater yields compared to all other treatments except the alfalfa and haylage oat companion crop treatment. These results indicate that proper management of the companion crop system for highest yields and best performance of alfalfa has not been determined or established.

Okito, Pungu. "Origins Of The Y Genome In Elymus." DigitalCommons@USU, 2008. https://digitalcommons.usu.edu/etd/95.

Abstract:

The Triticeae tribe DUMORTER in the grass family (Poaceae) includes the most important cereal crops such as wheat, barley, and rye. They are also economically important forage grasses. Elymus is the largest and most complex genus with approximately 150 species occurring worldwide. Asia is an important centre for the origin and diversity of perennial species in the Triticeae tribe, and more than half of the Elymus are known to occur in the Asia. Cytologically, Elymus species have a genomic formula of StH, StP, StY, StStY, StHY, StPY, and StWY. About 40% of Elymus species are still unknown for the genomic constitution and some have questionable genomic combination. However, the origin of the Y genome is unknown. In order to identify the origin of the Y genome, 212 accessions of Elymus, Pseudoroegneria, and Hordeum species were tested using a Y genome specific Sequence Tagged Site (STS) marker. We obtained evidence supporting the hypothesis that the Y genome in some Elymus species shared a progenitor genome with the St genome. Our study suggested that Pseudoroegneria spicata (PI 232134), P. ferganensis (T 219), and P. libanotica (PI401326) are the donors of the Y genome in the Elymus species. The DNA sequences of the Y-genome marker in these three Pseudoroegneria species are more similar to those obtained from Elymus species having the Y genome than those from Hordeum marinum and H. murinum, making the Xa and Xu genomes less likely the donors of Y genome.

Full text

Abstract:

Glyphosate-resistant weeds in North Dakota and Minnesota sugarbeet growing regions have necessitated research on S-metolachlor. S-metolachlor can be applied early-postemergence in sugarbeet but has not been labeled preemergence as reductions in sugarbeet safety have been observed. Field and growth chamber experiments were conducted to determine crop safety from S-metolachlor applied preemergence. S-metolachlor readily bonds to soil clay and organic matter. High clay and organic matter soils buffer S-metolachlor from soil solution and increase crop safety. Sugarbeet emergence was affected by soil series, temperature, and soil water, but was not affected by S-metolachlor or S-metolachlor rate. S-metolachlor affected sugarbeet growth, but a rate of 0.54 kg ai ha^-1 was safe across soils and growing conditions. No differences in varietal tolerance were observed. S-metolachlor applied immediately after planting or at the cotyledon and two-leaf stage injured sugarbeet less than application 3, 5, or 7 d after planting.

Abstract:

The effect of black polyethylene mulching and drip irrigation on the yield and quality of three cultivars of bell pepper was studied during the 1987 growing season. This study was conducted on a Pembroke silt loam soil on the Western Kentucky University Farm in Bowling Green, Kentucky. The experimental design was a split-plot arranged in randomized complete blocks in four replications with treatment as the main plot and cultivars as the sub-plot. 'California Wonder,' 'Lady Bell F1 Hybrid: and' Keystone Resistant Giant' cultivars of bell pepper were established in the field during the last week of May. The cultivars were grown using black polyethylene, with application of irrigation (no mulch) and without irrigation or mulch (check) Irrigation was initiated in early August and continued throughout the remainder of the growing season; the amount per application was 158.8 m3/ha. At harvest, mature green fruit were removed from the plant, weighed, and classified as grade I or II. There were significant differences at the 5% level in the yield of the cultivars. There were significant differences at the 5% levels among the yields of the treatments. the higher yield was obtained with irrigation, followed by the use of mulch. The better yield under each of the three treatments was obtained with the cultivar Lady Bell. The production of grade II peppers Was higher than the production of grade I peppers, the average yield was 48.82 MT/ha, and 21.99 MT/ha, respectively. The yield of bell pepper grade II was higher in all three treatments.

Abstract:

The effects of within-row spacings and cultivars on the yield of bush snap beans (Phaseolus vulgaris L.) were studied in two experiments. In each experiment, two cultivars and four within-row spacings (8, 15, 23 and 30 cm) were arranged in a split-plot with four replications. Spacing treatments were the whole plots and cultivars were the split plots. In 1988, the two cultivars were 'Blue Lake 274' and 'White Half Runner'. In 1989, the cultivars were 'Blue Lake 274' and 'Kentucky Wonder 125'. All rows were spaced 91 cm apart. Pods were harvested and oven dried. The data were subjected to analysis of vlriance procedure for a split-plot design, assuming a fixed model. In 1988, White Half Runner was significantly higher yielding than Blue Lake 274. In 1989, yield of Kentucky Wonder 125 was significantly greater than that of Blue Lake 274. Bean yields were significantly influenced by spacing treatments in 1988 and 1989. Yields per plant were significantly higher for the 30-cm than for the 15- and 8-cm spacings. Yields for the 23-cm spacing treatment were significantly higher than those for the 8-cm treatment. Yields per meter of row showed no significant differences at any spacings. The linear effect for spacings was significant for both yield per meter of row and yield per plant in 1988 and 1989.

Thompson, Leslie. "Efficacy of Sucker Control Method and Effect of Topping Height on Axillary Bud Growth in Dark Fire-Cured Tobacco." TopSCHOLAR®, 2001. http://digitalcommons.wku.edu/theses/640.

Full text

Abstract:

The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as suckercides are commonly used to prevent axillary bud growth. Research has demonstrated that topping time, height, and sucker control method influence the quality and yield of the final product. Delaying topping past a critical developmental stage has been shown to reduce leaf yield. Topping height varies among geographical regions with most dark tobacco producers topping to a height of 12 to 16 leaves. Previous studies indicate that plants topped to 16 leaves had higher leaf yields than those topped to 12 leaves if late-season soil moisture was adequate. The opposite effect was observed when late-season soil moisture was below average because the small upper leaves on plants topped to 16 leaves did not receive the moisture needed for proper development. The moisture they did receive could have been diverted to improve the yield and quality of the larger, more valuable leaves if the smaller ones had been removed. Several options exist for chemical control of tobacco axillary buds ranging from contact to systemic materials. Performance of these materials is influenced by several factors including environmental conditions prior to and following application. Research plots were established at Western Kentucky University's Agricultural Research and Education Complex in Bowling Green, Kentucky to evaluate the efficacy of various sucker control methods and evaluate the effect of topping height on axillary bud growth. Data collection was completed in the summer of 2000. Three sucker control methods and three topping heights were investigated. The first sucker control method was a single application of a local systemic suckercide at topping. The second method was a sequential application using a contact suckercide at topping followed by a local systemic applied seven days later. The third method, which served as the control, was topping the plants but not applying any suckercides. The experiment utilized a split-plot design with 9 treatments and 4 replications. The plots consisted of two 7 m rows per plot, with 102 cm row spacing and 89 cm in-row spacing. Data collected include number of suckers per plant and kilograms of sucker biomass per plant. Statistical analysis indicated no sucker control method by topping height interaction; thus sucker control and height data are discussed separately. Suckers per plant and sucker biomass per plant did not differ among those plots receiving a suckercide application. Topping height did not influence sucker number or biomass.

Abstract:

This research project that was conducted to provide evidence that composted organic waste materials do provide comparable nitrogen absorption efficiency in relation to an organic slow release fertilizer. Western's compost facility supplied the two different organic wastes, which had been composted for 1 year. The materials used were composted urban leaf litter, sawdust/manure mixture at a 50/50 ratio by volume and an organic fertilizer IBDU. These materials were applied to one cultivars of (Agrostis capillaries) and three cultivars of (A. palustris) at the rate of .S^/IOOO**2 in the months of April, June, and September. The plots were sampled one month after application to evaluate the nitrogen concentration of the leaf and thatch material. The nitrogen concentration was measured by using a Leco 2000 CHN provided in the Dept. of Chemistry. In comparison of N recovery in leaves, "Exeter" had lower N concentration than the other cultivars in October and no difference in May and July of the first year. The leaf concentration for the second year showed that Penncross and L-93 were lower in May and were the same for the other two sample dates. There was no difference found in the N concentration of thatch among the fertilizer sources for both years. IBDU showed better N recovery in all but the last sample date where all treatments were the same.

Abstract:

Isolates of Citrus Tristeza Virus (CTV) in Belize may be causing inverse stem pitting, stunting, and slow decline on sweet and sour orange rootstock combination on field trees. One isolate on Cleopatra mandarin rootstock expressed no field symptoms but may be a possible source of a detrimental isolate to more susceptible citrus rootstock combinations. Field plants and field source inoculated indicator plants were used in this study. The first objective was to determine whether field trees of sweet Valencia orange trees that expressed symptoms of CTV would test positive to a polyclonal (mild and severe symptoms) and a monoclonal (severe decline) antibody. Of the 81 trees tested, 56% tested positive to a polyclonal antibody G-604. None of the trees tested positive to the monoclonal antibody MCA-13. The second objective was to determine the biological and serological reactivity on host indicator plants of some of the most symptomatic trees having highest optical density value readings from the ELISA test. Mexican lime showed mild to moderate vein clearing on three of the isolates tested, while sweet orange showed mild to moderate translucent veins on two of the isolates tested. Four isolates from the indicator host plants tested positive to polyclonal antibody G-604 but none tested positive to MCA-13. The third objective was to determine if there were any differences among the nucleotide sequences of three CTV isolates. The CTV coat protein gene (CPG) of isolates which reacted to a polyclonal antibody G-604 but not to monoclonal antibody (MCA-13) was selectively amplified by polymerase chain reaction from infected tissue extracts and sequenced using negative sense CN 407 primer. All three isolates revealed between ninety-eight and ninety percent significant identities to known CTV isolates previously characterized from citrus growing regions around the world.

Abstract:

Field experiments were established in 2000 and 2001 at the Agricultural Research and Education Complex in Bowling Green, Kentucky to evaluate herbicide efficacy on annual morningglory (Ipomoea spp.) species and other weeds. A randomized complete block design was utilized in each study with each treatment being replicated three times. Plots consisted of four 76 cm rows, 9.1 m in length. The two center rows of each plot were treated, with the outside rows of each plot serving as a weedy check. Crop response, weed control, and grain yield data were collected. Four different experiments were conducted. Two experiments utilized treatments of glyphosate and sulfosate alone and with tankmixes on glyphosate-tolerant soybeans. Two experiments examined various herbicide tankmixes applied to non-glyphosatetolerant soybeans. Soybean injury influenced by postemergence treatments of glyphosate and sulfosate alone and with chlorimuron-ethyl ranged from 0 to 5% four days after treatment (DAT) with the addition of chlorimuron-ethyl resulting in greater injury. Morningglory control 14 DAT ranged from 48 to 63% with sulfosate at 700 g ai/ha providing less control than glyphosate at 1120 g ai/ha. No treatment differences occurred 29 and 42 DAT. No statistical differences among treatments occurred among other weed species evaluated. Soybean injury influenced by postemergence treatments of glyphosate and sulfosate alone and with fomesafen and chloransulam-methyl 4 DAT ranged from 0 to 17% with the addition of fomesafen resulting in greater injury than the addition of chloransulam-methyl. Momingglory control 14 DAT ranged from 60 to 88% with glyphosate + imazethapyr at 840 + 71 g ai/ha providing the least control and sulfosate + fomesafen at 700 + 201 g ai/ha providing greater control. Soybean injury influenced by pre and postemergence treatments 7 DAT ranged from 0 to 30% in conventional soybeans. Applications of carfentrazone resulted in the greatest injury. Momingglory control 20 days after planting (DAP) ranged from 0 to 99% with chloransulam + sulfentrazone providing the highest control. Momingglory control 28 DAT ranged from 30 to 99% with s-metolachlor + metribuzin + acifluorfen + fenoxaprop-ethyl + fluazifop-P providing the least control. Common cocklebur control ranged from 13% to 97% 20 DAP with pendimethalin + imazethapyr providing the least control. Treatments containing aciflourfen + bentazon controlled common cocklebur > 80% 28 DAT. Soybean injury influenced by preemergence and postemergence treatments 7 DAT in conventional soybeans ranged from 0 to 33% with sulfentrazone + clomazone + chlorimuron-ethyl + carfentrazone resulting in the greatest injury. Momingglory control 7 DAT ranged from 0 to 99% with sulfentrazone + clomazone plus chlorimuron-ethyl + carfentrazone having the greatest control. Momingglory control 28 DAT ranged from 82 to 94% with no differences among treatment.

Abstract:

It is estimated that the global population will reach approximately 10 billion people by 2050 and 66% of the world population will live in urban areas. This growth in cities creates demand for fresh products to maintain a healthy population, a product that often exposed to a long journey to reach the consumer, not only losing quality and nutritive value in the process, but also requiring a significant cost of fossil fuel for transportation and storage. However, the world’s agricultural land among being limited, is also facing major problems such as pollution, salinization and drought that do not favor crop production. The need for food security has paved the way for landless agriculture, becoming more popular in the urban area and becoming a part of urban farming. This article aims to examine hydroponic technologies to help expand the knowledge of their application in terms of science, origin, dynamics and farming systems. Among the benefits of soilless cultures; reservation of cultivated land for main crops; saving at least 90% of irrigation water; use of almost constant amount of recycled water; successfully growing almost every vegetable crops and having highest productivity compared to conventional agriculture. Therefore, it is an indispensable solution in areas where arable land is not available or in saline-prone areas, in short, wherever there is competition for land and water. The purpose of this study is an overview of soilless farming systems, explaining the most widely used hydroponic system, the importance of water quality, nutrient content, grown crops and ultimately cost benefit in terms of economics.

Abstract:

The stationary experiment on the comparative study of the direct sowing and traditional cultivation technology was laid in 2015–2016 at the trial field of the FSBSI “Research Institute of Agriculture of Crimea”. Two five-course crop rotations were taken as a base; all fields were included in the crop rotation. During the years of research, we observed mixed weed infestation. No matter what cultivation technology was applied, actual weed flora at the fields with winter crops was represented by overwintering and winter weeds; at the fields with spring crops – annual spring weeds. There were no rootstock grasses and rhizomatous perennial weeds or there were few of them at all fields in the experimental crop rotations both by traditional cultivation technology and direct sowing. Timely and high-quality weed control put the direct sowing on equal footing with the traditional one. It is advisable to change herbicides, their doses, as well as use tank mixes, after moving to a direct sowing system.

Abstract:

The research aimed to study the influence of different tillage-and-planting systems on the soil density of chernozem southern in the central steppe of the Crimea. The soil density is a very important parameter both in the direct seeding and conventional tillage since the no-tillage crop production system is that left soil undisturbed. The stationary experimental site is situated in the village of Klepinino Krasnogvardeyskiy district Republic of Crimea (Department of Field Сrops, FSBSI “Research Institute of Agriculture of Crimea”). This report provides data for 2019. Even though the direct seeding does not include topsoil loosening, the soil density parameters are optimal (1-1.4 g/cm3) in the 0-10-centimeter layer for the development of the roots of the studied crops. In the 10-20 and 20-30 cm layers, the soil in the reporting period is a little over-compacted despite the farming system

Abstract:

Aim/Purpose: This paper addressed the topics of sustainable agronomy, aquaculture, hydroponics and soil monitoring methods that show how to move towards a repairing mode and bioremediation in many locations across the globe. Background: Sixty percent of the world’s major terrestrial ecosystems are being degraded; the human ecological footprint is spreading across the globe. The major human impact on terrestrial ecosystems in the form of depletion of ground water, over grazing of livestock, clearing for agriculture, timber and urban development, soil damage from off road vehicles, hydroelectric dams and reservoirs, and air pollution from urban areas and power plants. The cost to bio remediate is in the trillions. Methodology: AG biotech methodologies and applications Contribution: The paper bridges such gaps and informs about brave entrepreneurs and university and community individuals with innovative ideas and emerging technologies that gain the momentum for funding and monitoring nutrient uptake and toxic removal of harmful chemicals from water, soil, plants and fish for restoration to take place. Such techniques begin to conquer the giant by restoring the wealth to our soils and water, rural and urban farmlands and forests that retain and capture natural capital and ensure that nutrition and value added resources minerals are not lost. Findings: Biomonapp can detect and make recommendations for repairing & making sustainable solutions, many entrepreneurs & academics have pioneered ways to find SUS solutions Recommendations for Practitioners: Read from the articles and books listed in the references of this paper to understand the need for bioremediation. Use Biomonapp to diagnose water, soil & fish problems & find solutions. Attend conferences & seminars about SUS responsibility & phytoremediation Recommendation for Researchers: To investigate the phytoremediation and bioremediation techniques. Applications for Biomonapp for plants, water, soil, & animals to rejuvenate and repair water, soil and urban & rural communities Impact on Society: These ideas give the power back to local people who can learn to enhance their lives not only by foods but the sustainable green jobs that are being created to make sure urban and rural areas truly are sustainable. Future Research: The results of monitoring with biosensors & bio monitoring methods with regards to sustainable bioremediation, renovating, continued SUS responsibility training, continued evidence of repair and protecting natural capital & ecosystem services
