Abstract:
Castillo Grande, ubicado en Huánuco - Perú, presenta el problema de contaminación producido por el incremento de los residuos sólidos, en especial de los orgánicos, que no son aprovechados, por lo que se propone la forma de degradación de dichos residuos, planteando el objetivo, de evaluar la acción de microorganismos efectivos provenientes de distintas fuentes en la degradación de los residuos sólidos orgánicos, y su influencia en la producción de compost con mejores parámetros químicos. La metodología empleada fue un diseño experimental completamente al azar, con tres tratamientos (Compost1, Compost2 y Compost3) y tres repeticiones por tratamiento, donde los análisis de las variables, tales como periodo de degradación de residuos sólidos orgánicos y parámetros químicos del compost, estuvieron en función de los valores promedios y de dispersión. Los resultados no reportan diferencias estadísticas significativas entre los tratamientos en el periodo de degradación; pero sí en ciertos parámetros químicos. El Compost1 es el que reportó menor periodo de degradación y mayores contenidos de materia orgánica en estado seco, humedad, nitrógeno, fósforo, potasio, magnesio, sodio, zinc y manganeso, cumpliendo en gran parte los niveles establecidos por la Norma Técnica Peruana 201.208:2021; mientras que los mayores contenidos de Ca y Fe se registró con el Compost3. Concluyendo que los microorganismos efectivos provenientes de la hojarasca, son los adecuados para descomponer residuos sólidos orgánicos y producir compost en menor tiempo y con buenos parámetros químicos.

Abstract:
The aim of this work was to compare the application of biochar, compost, and their mixtures on soil fertility and crop yields using a volcanic Mediterranean soil. For this reason, three types of organic amendments (OAs) were selected: compost1, made from olive mill waste and orchard pruning residues; compost2, made from olive mill waste, animal manure and wool residues; and biochar made from beech wood pyrolyzed at 550 °C. When selected, the OAs were characterized chemically for organic carbon (OC), total N, pH, electric conductivity (EC) and the bulk fraction of organic matter using 13C CPMAS NMR spectroscopy. In addition, soil chemistry was analysed at the end of each year for the following parameters: pH, OC, total N, CaCO3, P2O5, NH4, FDA and EC. Results showed that biochar had the highest OC and the lowest N and EC compared to both composts. Moreover, 13C CPMAS NMR showed that biochar had the lowest content of O-alkyl, methoxyl- and alkyl-C and the highest content of aromatic-C. On the other hand, compost2 and compost2+biochar mixture reduced Aubergine yield by −60% and −40%, respectively, and tomato yield by −50% and −100%, respectively. Nevertheless, a significant increase in onion and rape yields were observed when compost1, compost1+biochar and compost2 were applied, while biochar and compost2+biochar significantly decreased the yield of these crops. Overall, our results highlight that the effect of OAs on crops yield is largely variable and influenced by the interaction with soil chemistry.

Abstract:
Sandy desert soil in Sudan are characterised by low content of organic matter, small water holding capacity and low crop productivity. Methods to enhance crop productivity on these environments, such as land application of composts, are of great importance. Field experiments were conducted on a sandy soil to determine the effects of two types of composted manures on growth and yield of two sorghum varieties grown under rainfed conditions. Two sorghum cultivars (Butana and Arfa Gadmak were sown under chicken manure (CM) compost (5 t ha-1), CM compost with NPK (36 kg ha-1), farm manure (FM) compost (20 t ha-1), FM compost with NPK (36 kg ha-1), CM compost with FM compost (1:1, wt/wt, 12.5 t ha-1), CM and FM composts with NPK (36 kg ha-1), only NPK (36 kg ha-1) and control (no composts or NPK). Application of composts increased organic soil carbon by 50% and available phosphorous (P) between 43 to 105%, whereas, pH and bulk density were decreased by 2 and 6%, respectively. Soil moisture contents in compost treated plots were 56–98% higher than control plots. Mixing compost with NPK increased leaf area index over NPK alone by 28% but the highest values were found in plots treated with chicken compost or integrated with NPK compared to NPK application alone. Incorporation of compost increased dry matter yield compared to control by 17–53% and increased grain yield by 1.8 to 3.1 fold in both sorghum varieties. Grain yield from plots treated with NPK, sole chicken compost or combined with NPK were similar for both varieties in both seasons. In general, the trend of grain yield of sorghum was in the order of NPK = chicken compost with NPK = chicken compost = farm manure compost with NPK  mixed compost with NPK = farm manure  control. In conclusion, integrating composts with NPK improved fertility of sandy soils, sorghum growth and yield. © 2020 Friends Science Publishers

Abstract:
The experiment entitled “Efficacy of different types of Composts on growth, yield and quality parameters of Okra (Abelmoschus esculentus L.) cv. Kashi Pragati” was conducted during Rabi season of the year 2020-2021 on experimental farm of Department of Horticulture, AKS University, Satna (M.P.). The experiment was laid out in a randomized block design with three replicated 12 treatments viz., T0: Without compost (Control), T1: 100% Vermicompost + 100% Biogas slurry compost, T2: 100% Vermicompost + 100% Mushroom Spent compost, T3: 100% Biogas slurry compost + 100% Mushroom Spent compost, T4: 100% Vermicompost + 100% Biogas slurry compost +100% Mushroom Spent compost, T5: 100% Vermicompost + 50% Biogas slurry compost, T6: 100% Vermicompost + 50% Mushroom Spent compost, T7: 100% Biogas slurry compost + 50% Vermicompost, T8: 100% Biogas slurry compost + 50% Mushroom Spent compost, T9: 100% Mushroom Spent compost + 50% Vermicompost, T10: 100% Mushroom Spent compost + 50% Biogas slurry compost, T11: 50% Vermicompost + 50% Biogas slurry compost +50% Mushroom Spent compost. The results reveal that increase in Composts level had significant response on vegetative growth yield and quality of Okra. The treatment T4-100%Vermicompost +100% Biogas slurry compost +100% Mushroom Spent compost was found to be the best treatment among the different treatments with growth, yield and quality for Okra under satna condition.

Abstract:
More and more waste is being generated in the world. One form of waste processing is the composting process. This work aims to study the morphological composition of selected composts to determine the amounts of the various frac-tions contained therein. In the present work, four types of composts are presented to study their morphological composi-tion. Composted grass, backyard compost, soil improver formed after composting green waste, and stabiliser – waste formed due to mechanical-biological processing of municipal waste taken from the Municipal Waste Mechanical-Biological Treatment Facility – were studied successively. Fifty samples of 2 kilograms each were taken from each group of composts, respectively. Each sample was divided into seven fractions: organic waste, plastics, ceramics, paper and cardboard, glass, metal and others. After analysis, it can be concluded that it is very difficult to obtain homogeneous compost due to the heterogeneity of the raw material. The results are accurately presented in tables with the distinction of the different fractions. It was found that mowed grass contained the most organic matter, while stabiliser contained the least. The least amount of plastic was found in backyard compost, and the most in stabiliser.

"Sustainable Growing Media Blends with Woody Green Composts: Optimizing the N Release with Organic Fertilizers and Interaction with Microbial Biomass."

Abstract:
The aim of the current study was to create a high quality growing medium blend that replaces 70 vol% peat with 40 vol% woody green compost and 30 vol% bark compost and organic fertilizers (i.e., blood meal and chitin), all locally sourced. A range of “woody composts”, i.e., green composts based on feedstock selection with mainly woody material from tree prunings, were produced for this purpose at green compost facilities. First, the woody composts were characterized chemically and biologically, including their microbial biomass and net N release. In comparison with regular green composts or vegetable, fruit and garden (VFG) waste composts, woody composts are more suitable for use in growing media due to their lower pH, EC and inorganic C content; however, the woody compost had a low N mineralization rate. Three types of composts supported a higher microbial biomass than wood fiber or bark compost. The additional mineral N release after 100 days for compost mixed with blood meal was tested for different VFG and green composts. A significantly higher additional net N release was measured for composts with higher initial mineral N concentrations (317 mg Nmin/L) as well as VFG composts (417 mg Nmin/L) than for green composts with a lower initial mineral N concentration (148 mg Nmin/L). In a last step, woody compost, bark compost, wood fiber, coir and peat were mixed in different ratios, resulting in six blends ranging from 100% peat-free to 100% peat. Two batches of woody compost were compared, and the blends were mixed with blood meal or chitin. A strong effect of both the organic fertilizer and the blend composition on the mineral N release was observed, with a clear link between the microbial biomass and the net N release. There was a significant negative correlation between the net change in microbial biomass and the net N release (R = −0.85), which implies that a larger increase in microbial biomass during incubation with the organic fertilizer resulted in less N mineralization. The blends containing woody compost scored better for nitrification activity, as the NH4-N concentrations were lower in these than for the blends without woody compost. For the peat blends, no effect on the microbial biomass was observed after addition of organic fertilizers; mineral N did increase, however. Woody composts have the potential to be used in high vol% in growing media blends, but the blends still need further optimization when supplemented with organic fertilizers.

Abstract:
Compost (biosolids and yard trimmings at 134 t·ha-1) was applied to a sandy field soil with fertilizer at 0%, 50%, or 100% of the grower's standard rate (71N-39P-44K kg·ha-1 broadcast and 283N-278K kg·ha-1 banded in bed centers). Raised beds were constructed and covered with polyethylene mulch, and `Elisa' bell peppers (Capsicum annuum L.) were transplanted into the plots. Foliage samples taken at early harvest indicated that leaf N concentrations increased and Cu concentrations decreased with increasing fertilizer rates. Leaf concentrations of P, K, Ca, and Mg increased and Cu decreased in plots amended with compost. Marketable pepper yields from plants grown in plots amended with compost were 30.3, 35.7, and 31.1 t·ha-1 in plots with 0%, 50%, and 100% fertilizer rate, respectively. Without compost, yields were 19.8, 31.1, and 32.0 t·ha-1 with 0%, 50%, and 100% fertilizer rate. `Valient' cucumbers (Cucumis sativus L.) were seeded through the same polyethylene mulch into the previous pepper plots. Marketable cucumber yields were not affected by residual fertilizer, but were higher (26.8 t·ha-1) in plots amended with compost than without compost (22.7 t·ha-1). In a second experiment, a biosolids-yard trimming-mixed waste paper (MWP) compost and a biosolids-yard trimming-refuse-derived fuel (RDF) compost were applied at 0 or 134 t·ha-1 with fertilizer at 0%, 50%, or 100% fertilizer rates, respectively. With no fertilizer, total yields from pepper plants were higher in plots amended with composts than without composts. In 50% fertilizer plots, yields were similar between compost treatments. At 100% fertilizer rate, yields with MWP compost were significantly higher than yields with RDF compost or with no compost. In plots without fertilizer or with 50% fertilizer rates, mean fruit size (g/fruit) was largest with MWP compost, intermediate with RDF compost, and smallest without compost. With 100% fertilizer, mean fruit size was larger with either compost than without compost. Composts combined with low rates of fertilizer generally produced higher pepper yields than other treatments. Residual compost increased yields of a subsequent cucumber crop. Yields from pepper plants without fertilizer were higher when soil was amended with composts with added MWP or RDF, but, with fertilizer, yields were similar or only slightly increased.

Abstract:
This study elucidates an attempt to prepare compost from kitchen, dairy and drainage wastes and estimate their manorial value, and to examine the effect of prepared compost on the properties of post-harvest soil. The composts on individual item were prepared by the recently practiced quick composting method. The composts were applied in four different plots; three were treated with composts and the rest with no-treatment. The red amaranth was taken as the reference crop for the present study. The plots treated with dairy and kitchen wastes composts conserved the maximum soil moisture, available phosphorus and exchangeable potassium. The compost prepared from dairy wastes showed the best performance in conserving soil organic carbon and organic matter. The kitchen wastes compost supplied the maximum amount of nitrogen content to the soil. The dairy and kitchen wastes compost was better than the drainage wastes compost for sustainable crop production and in improving soil chemical properties and maintaining good soil quality. Dairy wastes compost showed the best performance in terms of canopy developing the plant height and root length. The highest yield was found in dairy and kitchen wastes compost treated plots. For growth and yield of red amaranth, dairy, kitchen and drainage wastes compost were superior to conventional farming as sustainable agricultural inputs.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16872 Progress.

Abstract:
An agricultural compost of chicken manure and cranberry pomace, a municipal compost of biosolids and mixed municipal solid wastes, and a compost of autumn leaves were evaluated for production of turfgrass sods and wildflower sods. Composts made during the year of the experiment and one-year-old composts were compared. The experiment was conducted outdoors with composts layered on sheets of plastic laid on the soil surface. The sheets of plastic controlled soil-borne weeds and facilitated harvest of sods. The best sods measured by stand and growth were produced with the agricultural compost, which was rich in N (avg. 1.7%) and low in NH4+ (avg. 135 mg/kg). High NH4+ (>900 mg/kg) appeared to limit stand establishment with the fresh municipal compost. The leaf compost was too low in N to support sod growth without fertilization. Aging of each compost improved its capacity to support sod production, apparently as a result of changes in the N status in the media.

 Physico-chemical characterization of composts made from poultry droppings and phosphate wastes from Togo The processing of natural phosphates in Togo generates phosphate wastes (sieve residues and phosphate mud) which cause many immediate environmental problems. The objective of this research work was to recover these wastes with poultry droppings in compost. Four composts have been elaborated: compost A made up of 66.7% poultry droppings and 33.3% phosphate mud; compost B made up of 66.7% poultry droppings and 33.3% sieve residue; compost C made up of 66.7% poultry droppings, 16.7% phosphate mud and 16.7% sieve residue and compost D made up of 100% poultry droppings. All the composts presented a temperature greater than or equal to 60°C during the maturation process. Compost D alone had a C/N ratio of >10. The CaO contents in the composts varied from 55.30 to 73.16 mg/gMS and those of P2O5 varied from 34.40 to 140 mg/gMS. The Na2O and K2O contents varied respectively from 15.13 to 24.01 mg/gMS and 12.60 to 36.80mg/gMS. All the composts produced were rich in nutrients and could be used to refurbish soils.

Abstract:
An interrogation of architecture's prevailing myths, and a practice for how to live and die well as an architect in the Anthropocene epoch.  It is an effort to combine joyful representation and speculation (because architecture is both too serious and not nearly serious enough), with philosophy, for still possible pasts, presents and futures. For this it leans mainly on the ideas of Donna Haraway, Gilles Delueze and Felix Guattari, to present a methodology called Nomad Storytelling. A methodology that aims to move between a multiplicity of adjacent sites as to care for them in appropriate ways, with the intention of contributing to the idea of relationally unmaking the environmental urgencies of the 21th century. It consists of 8 chapters dealing with juridical care, letting be as care, humour and shaming, fabulous speculation, non-quantifiable architecture as dissent and graphic design as a crucial part of remembering what the cost of architecture is beyond the monetary, in the end suggesting the idea of architect-as-worm and compost architecture. It’s about not telling another killer story, because they always end with apocalypse or dystopia, and instead tell stories of gathering and fabulous futures, as Ursula K. Le Guin called it. Because it matters which architectures architect architecture and which lines line lines.

During the composting of the solid fraction of swine wastewater, the temperature, reduction of total solids (TS), most probable number (MPN) of total coliforms (TC) and fecal coliforms (FC), volume and compost quality was evaluated. The larger biogas and methane potential production was presented by biodigestors WSFS, in larger HTR, and consequently presented the smallest remaining biogas potentials of production. Was verified methane potential production of 0.664 and 0.890 m³ methane/kg of volatile solids (VS), for WSFS and WOSFS respectively, with 15 days of HTR, demonstrated 34% efficiency in the conversion of organic matter to methane. However when evaluating the remainder methane potential production was observed 0.385 and 0.117 m³ methane/kg of VS for WSFS and WOSFS, with 15 days of HTR. The composting of solid fraction demonstrated is a good substratum for the process presenting a reduction 71% of TS and 100% for TC and FC.

Abstract:
Un effluent gazeux avec 3 COV (acétone, toluène et TCE) a été traité par biofiltration par 4 biofiltres B1-B4 avec des matériaux différents : un lisier de porc (organique) pour B1 et B2, la pouzzolane (minéral) pour B3 et un mélange des 2 supports pour B4. B1 et B2 ont atteint une efficacité d'élimination de 100% pour l'acétone et 90% pour le toluène. Pour B3 : seulement 50% pour le toluène. B4 a atteint des efficacités équivalentes à B1-B2 après ré-humidification du matériau. La dégradation du TCE a été faible pour les 4 biofiltres. La performance des biofiltres dépend de l'humidité, des pertes de charge et de la température. Le lisier est un bon matériau avec une flore microbienne efficace pour dégrader les COV par biofiltration, avec une durée de vie inférieure à celle de la pouzzolane. Celle-ci est très stable et poreuse, mais nécessite une inoculation et une longue acclimatation. Le mélange compost/pouzzolane permet une bonne performance de la biofiltration sur une longue période<br>A gaseous tributary with a mixture of 3 VOCS (acetone, toluene and TCE) was treated by biofiltration with 4 biofilters B1- B4 using different filtering materials : pig manure (organic) for B1 and B2, the pouzzolane (mineral) for B3 and a mixture of the 2 supports for b4. The elimination effectiveness attained by B1 and B2 was 100% for acetone and 90% for toluene. For B3, the maximum value for toluene was only 50%. B4 attained B1-B2 elimination effectiveness after re-watering of the media. TCE elimination effectivness remained very limited for the 4 biofilters. The performance of the biofilters depends on humidity, pressure drops and temperature. The pig manure is an excellent material for biofiltration, with excellent microbial flora degrading VOCS, but with a shorter life than that of pouzzolane, which is very stable and porous but required inoculation and a long acclimatization period. The mixture pouzzolane/manure has satisfying performance of biofiltation over long period

Abstract:
<p> The objective of this study was to determine the effects of propagation media containing composted material on the rooting of hardwood and softwood blueberry cuttings. The physical properties were measured at the end of the experiment. The media used were pine bark fines, composted pine bark with ammoniated nitrogen added, hardwood bark and composted chicken manure, pine bark and cotton gin waste, and control (peat moss and perlite, 1:1). All treatments resulted in a low number of rooted hardwood cuttings compared to the control. The total number of roots per cutting and alive cuttings hardwood cuttings was increased by pine bark and ammoniated nitrogen compared to the remaining treatments. The control treatment resulted in the highest number of roots per softwood cutting. None of the treatments increased the number of roots of softwood cuttings and the number of alive cuttings was increased by all treatments compared to the control.</p><p></p>

Abstract:
In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purposes. These composite materials utilize composted biosolids from the dairy industry as the main matrix (60%), blended with biodegradable polymers such as polybutylene adipate succinate (PBSA) and polylactic acid (PLA) as functional agents. This innovative approach contrasts with the prevailing literature on composite polymer materials, where polymers typically form the matrix and agricultural residues serve as fillers. Biosolids from Freskaleche S.A. undergo controlled thermal treatment and composting before being combined with PBSA and PLA polymers using an internal mixer. The development of these new compounds includes the evaluation of thermal stability, Fourier-transform infrared spectroscopy (FTIR), and mechanical properties. It is noteworthy that Compost/PBSA composites exhibit promising compatibility and thermomechanical properties resembling pure PBSA, suggesting their potential as thermoplastic materials for producing plastic-based agricultural products. Regarding Compost/PLA blends, compost enhances chemical reactions in PLA polymeric chains, significantly altering their thermomechanical properties. This research provides valuable insights into the use of biosolids for manufacturing composite materials, offering a sustainable approach to address agricultural challenges in the Cesar region.

Abstract:
Restoration of degraded lands and the development of beneficial uses for waste products are important challenges facing our society. In addition there is a need to find useful and environmentally friendly applications for the organic fractions of municipal and other solid waste. Recent studies have shown that composted wastes combined with gypsum or gypsum-containing flue gas desulfurization by-products enhance restoration of sodic soils and acidic minespoils. The mechanism by which this synergistic effect occurs in systems at opposite pH extremes appears to involve enhanced Ca migration and exchange. Our original research objectives were to (1) identify and quantify the active compost components involved in Ca transport, (2) determine the relative affinity of the compost components for Ca and competing metals in the two soil/spoil systems, (3) determine the efficacy of the compost components in Ca transport to subjacent soil and subsequent exchange with native soil cations, and (4) assess the impacts of compost enhanced Ca transport on soil properties and plant growth. Acidic mine spoils: During the course of the project the focus for objective (1) and (2) shifted more towards developing and evaluating methods to appropriately quantify Ca2+ and Al3+ binding to compost derived dissolved organic matter (DOM). It could be shown that calcium complexation by sewage sludge compost derived DOM did not significantly change during the composting process. A method for studying Al3+ binding to DOM was successfully developed and should allow future insight into DOM-Al3+ interactions in general. Laboratory column experiments as well as greenhouse experiments showed that in very acidic mine spoil material mineral dissolution controls solution Al3+ concentration as opposed to exchange with Ca2+. Therefore compost appeared to have no effect on Al3+ and Ca2+ mobility and did not affect subsoil acidity. Sodic alkaline soils: Batch experiments with Na+ saturated cation exchange resins as a model for sodic soils showed that compost home cations exchanged readily with Na+. Unlike filtered compost extracts, unfiltered compost suspensions also significantly increased Ca2+ release from CaCO3. Soil lysimeter experiments demonstrated a clear impact of compost on structural improvement in sodic alkaline soils. Young compost had faster, clearer and longer lasting effects on soil physical and chemical properties than mature compost. Even after 2 growing seasons differences could still be observed. Compost increased Ca2+ concentration in soil solution and solubility of pedogenic CaCO3 that is highly insoluble under alkaline conditions. The solubilized Ca2+ efficiently exchanged Na+ in the compost treated soils and thus greatly improved the soil structure.

Abstract:
Several procedures were developed that predict maturity (stability) of composts prepared from municipal solid wastes (MSW). A respirometry procedure, based O2 uptake by compost, predicted (R2=0.90) the growth response of ryegrass in composts and an acceptable level of maturity. Spectroscopic methods (CPMAS13-NMR and DRIFT spectroscopy) showed that the stabilizing compost contained increasing levels of aromatic structures. All procedures predicted acceptable plant growth after approximately 110 days of composting. MSW compost suppressed diseases caused by a broad spectrum of plant pathogens including Rhizoctonia solani, Pythium aphanidermatum and Fusarium oxysporum. A strain of Pantoea agglomerans was identified that caused lysis of hyphae of R. solani. Evidence was obtained, suggesting that thermophilic biocontrol agents also might play a role in suppression. 13C-NMR spectra revealed that the longevity of the suppressive effect against Pythium root rot was determined by the concentration of readily biodegradable carbohydrate in the substrate, mostly present as cellulose. Bacterial species capable of inducing biocontrol were replaced by those not effective as suppression was lost. The rate of uptake of 14C-acetate into microbial biomass in the conducive substrate was not significantly different from that in the suppressive substrate although specific activity was higher. The suppressive composts induced systemic acquired resistance in cucumjber roots to Pythium root rot and to anthracnose in the foliage. Composts also increased peroxidase activity in plants by the conducive substrate did not have these effects. In summary, the composition of the organic fraction determined bacterial species composition and activity in the substrate, which in turn regulated plant gene expression relative to biological control.

Full text
Abstract:
Induced Systemic Resistance (ISR) is a highly variable property that can be induced by compost amendment of potting media and soils. For example, previous studies showed that only 1 of 79 potting mixes prepared with different batches of mature composts produced from several different types of solid wastes were able to suppress the severity of bacterial leaf spot of radish caused by Xanthomonas campestris pv. armoraciae compared with disease on plants produced in a nonamended sphagnum peat mix. In this project, microbial consortia in the rhizosphere of plants grown in ISR-active compost-amended substrates were characterized. The plants used included primarily cucumber but also tomato and radish. Rhizosphere microbial consortia were characterized using multiple molecular tools including DGGE (Israel) and T -RFLP (Ohio) in both ISR-active field plots and potting media. Universal as well as population-specific bacterial and fungal PCR primers were utilized. T -RFLP analyses using universal bacterial primers showed few significant differences in overall bacterial community composition in ISR-active and inactive substrates (Ohio). In addition, the community members which were significantly different varied when different ISR-activecomposts were used (Ohio). To better characterize the shifts in microbial community structure during the development of ISR, population specific molecular tools were developed (Israel, Ohio).-PCR primers were designed to detect and quantify bacterial groups including Pyrenomycetes, Bacillus, Pan toea, Pseudomonas, Xanthomonas and Streptomyces as well as Trichoderma and Fusarium; two groups of fungi that harbor isolates which are ISR active (Isreal and Ohio). Bacterial consortia associated with cucumber plants grown in compost-amended potting mixtures were shown to be dominated by the phylogenetic taxon Bacteroidetes, including members of the genus Chryseobacterium, which in some cases have been shown to be involved in biocontrol (Israel). Nested-PCR-DGGE analyses coupled with long l6S rDNA sequencing, demonstrated that the Chryseobacteriumspp. detected on seed and the root in compost-amended treatments were derived from the compost itself. The most effective ISR inducing rhizobacterial strains were identified as Bacillus sp. based on partial sequencing of l6S rDNA. However, these strains were significantly less effective in reducing the severity of disease than Trichoderma hamatum382 (T382). A procedure was developed for inoculation of a compost-amended substrate with T -382 which consistently induced ISR in cucumber against Phytophthora blight caused by Phytophthora capsiciand in radish against bacterial spot (Ohio). Inoculation of compost-amended potting mixes with biocontrol agents such as T -382 and other microbes that induce systemic resistance in plants significantly increased the frequency of systemic disease control obtained with natural compost amendments.
