Agriculture waste has increased annually due to the global food demand and intensive animal production. Preventing environmental degradation requires fast and effective agricultural waste treatment. Aerobic digestion or composting uses agricultural wastes to create a stabilized and sterilized organic fertilizer and reduces chemical fertilizer input. Indeed, conventional composting technology requires a large surface area, a long fermentation period, significant malodorous emissions, inferior product quality, and little demand for poor end results. Conventional composting loses a lot of organic nitrogen and carbon. Thus, this comprehensive research examined sustainable and adaptable methods for improving agricultural waste composting efficiency. This review summarizes composting processes and examines how compost additives affect organic solid waste composting and product quality. Our findings indicate that additives have an impact on the composting process by influencing variables including temperature, pH, and moisture. Compost additive amendment could dramatically reduce gas emissions and mineral ion mobility. Composting additives can (1) improve the physicochemical composition of the compost mixture, (2) accelerate organic material disintegration and increase microbial activity, (3) reduce greenhouse gas (GHG) and ammonia (NH 3 ) emissions to reduce nitrogen (N) losses, and (4) retain compost nutrients to increase soil nutrient content, maturity, and phytotoxicity. This essay concluded with a brief summary of compost maturity, which is essential before using it as an organic fertilizer. This work will add to agricultural waste composting technology literature. To increase the sustainability of agricultural waste resource utilization, composting strategies must be locally optimized and involve the created amendments in a circular economy.

“…In addition to the substrate amount and components of the material, the amount of organic matter and nutrient content of the material can be important in the emergence of the microbial stimulating effect of organic fertilizers in the soil [39]. In addition, phosphatase activity was reported to be closely related to soil pH, total N, organic P, and clay content [40]. The test soil pH (7.06), total N amount (0.13%) and texture (clay loam) with total phosphorus (16144 mg kg -1 ) and organic matter content (74%) of the sludge, is thought to be responsible for the increase in soil alkaline phosphatase activity.…”

Since sewage sludge contains plant nutrients and organic matter, it has a potential to act as a soil conditioner for maintainig soil fertility in crop production. In this experiment, different quantities of stabilized and dried sewage sludge (SS) were applied to a calcareous soil. Treatments used for this study were 0 t ha -1 (SS0/control), 20 t ha -1 (SS2), 40 t ha -1 (SS4), 60 t ha -1 (SS6), 80 t ha -1 (SS8) respectively. This study was aimed to investigate the changes in soil microbial dynamics by application of sewage sludge during growing crop conditions. A field experiment was done by using randomized blocks design and every treatment was replicated four times. Soil samples were collected at three different periods of plant growth. Number of bacteria (heterotrophic aerobic mesophilic) and changes in soil enzyme activities (nitrification, nitrate reductase, urease, alkaline phosphatase, β-glycosidase) were examined. According to the results, it is clear that the sludge applications have stimulating effect both on soil enzyme activities (excluding nitrate reductase) and the number of bacteria. With the application of sewage sludge soil microbial dynamics significantly increased (nitrification = 41.72%, urease = 35.14%, alkaline phosphatase = 43.29%, β-glycosidase = 59.64%, number of bacteria = 91.66%) as compared to the control.

Composting and vermicomposting are sustainable strategies to transform organic wastes into organic amendments, valuable as potting media or soil conditioner. However, the negative aspects of these processes are emissions of greenhouse gases and odorous molecules and final product potentially containing toxic compounds. These negative aspects can be limited through the addition of organic, inorganic or biological additives to the composted or vermicomposted mixture. The aims of this review are (1) to present the main characteristics of composting and vermicomposting processes with and without additives, (2) to show the influence of additives on greenhouse gas emissions during waste degradation and (3) to report the effects of additives on the properties of the final products (heavy metal and nutrient contents), in view of their use as a soil conditioner or potting media. Finally, the feasibility and potential environmental benefits of co-composting and co-vermicomposting are discussed. Our results show that additives affect composting parameters such as temperature, pH and moisture and thus have an impact on the composting process. They may be used to reduce gas emissions and mobility of mineral ions. The various additives have contrasting effects on the quality of the final product and its impact on soil quality. The use of worms and additives seems to increase plant available nutrient contents, while decreasing N leaching, heavy metal mobility and composting time. Cocomposting and co-vermicomposting strategies need to be locally optimised, involving the generated amendments in a circular economy to improve sustainability of agricultural systems.
