“…Similar results have been reported by Sun and Huang with S-H mixture in Fusarium wilt of watermelon, where it supported higher length of vines [17]. Organic amendments were found to be an excellent source of nutrition, which favor native antagonists to proliferate and suppress the pathogen by antibiotic production or competition [4]. Pre-incubation of Trichoderma in different composts improved the degree of protection by pre-establishing and multiplying of antagonists in a large number in composts.…”

Compost is beneficial for agriculture fields in many ways such as soil conditioner, fertilizer, and natural pesticide and above all it helps to manage organic wastes and adds vital humic acids to soil. Four indigenous composts prepared from readily available organic wastes viz. vermicompost, banana, NADEP, and Calotropis were used in the present investigation for growth and disease suppression in mung beans. The composts were amended with Trichoderma viride in the concentration of 0.1 and 0.2% to determine their influence on length and weight of roots and shoots, disease incidence, soil moisture, and soil microflora in plants. The best results were observed in the treatment with T. viride (0.2%), followed by T. viride (0.1%) in vermicompost, while the treatment T. viride (0.1%) with Calotropis compost showed little growth and suppression of disease. All composts enhanced the soil moisture content and microbial populations in amended soil resulting in the reduction of disease incidence. Among T. viride enriched composts, the counts of fungi, bacteria, and actinomycetes were higher in the vermicompost and banana compost‐amended soils. Thus, preparing these composts from readily available organic wastes and amending soil with T. viride enriched composts hold a great promise for improving soil fertility and suppressing the soil‐borne plant pathogens for sustainable agriculture.

“…In contrast, many composted materials possess antagonistic microflora that can suppress pathogens (Hoitink et al,1991). Although direct commercial application of the antagonistic properties of composted materials in growing media has proved difficult due its variable nature (St. Martin and Braithwaite, 2012), several antagonistic agents have been isolated, and microbial preparations are now marketed as additives to media not only for control of pathogens but also to accomplish biological control of insects.…”

Organic growing media are essentially bulk products. Availability in large quantity allied to its excellent air and water retention, low pH and salinity, and freedom from pests and diseases has led to peat being the dominant organic constituent of growing media in many parts of the world for the last 50 yr. The unique microporous properties of Sphagnum peat and its resistance to degradation are matched by few other growing media constituents. Nevertheless, local scarcity of Sphagnum peat and the expense of transport has led to the use of other materials in growing media. Notable among these is coir, which unlike peat, a CO2 sink, is widely regarded as a rapidly renewable resource. Indeed, advances in processing and quality control in situ have led to a huge upsurge in the export and use of coir in growing media, particularly in Europe but also in the western United States. Locally available organic materials such as bark, composted materials including green (yard) wastes, municipal solid wastes, and even sewage sludge are also used in growing media. While possessing advantages such as the high air content of bark and nutrient supply of many composted materials, these media components may have disadvantages, from limited supplies due to bioenergy pulls and N lock‐up in bark, to physical, chemical, and microbial contaminants in composts. Current innovative approaches involve increasing use of wood fiber in Europe, whole pine‐tree thinnings in the United States, and realizing the use and transformation of composted wastes as next‐generation constituents of growing media.

“…The decomposition of OM under controlled aerobic conditions can lead to a stable, humus-like end product known as compost [47]. Compost can be produced from a wide array of organic materials, including agrarian (crop residues, animal manures) and municipal solid waste and sewage sludge.…”

Potential Benefits and Risks for Soil Health Derived From the Use of Organic Amendments in Agriculture

2019

The use of organic amendments in agriculture is a common practice due to their potential to increase crop productivity and enhance soil health. Indeed, organic amendments of different origin and composition (e.g., animal slurry, manure, compost, sewage sludge, etc.) can supply valuable nutrients to the soil, as well as increase its organic matter content, with concomitant benefits for soil health. However, the application of organic amendments to agricultural soil entails a variety of risks for environmental and human health. Organic amendments often contain a range of pollutants, including heavy metals, persistent organic pollutants, potential human pathogens, and emerging pollutants. Regarding emerging pollutants, the presence of antibiotic residues, antibiotic-resistant bacteria, and antibiotic-resistance genes in agricultural amendments is currently a matter of much concern, due to the concomitant risks for human health. Similarly, currently, the introduction of microplastics to agricultural soil, via the application of organic amendments (mainly, sewage sludge), is a topic of much relevance, owing to its magnitude and potential adverse effects for environmental health. There is, currently, much interest in the development of efficient strategies to mitigate the risks associated to the application of organic amendments to agricultural soil, while benefiting from their numerous advantages.
