“…Composting is an aerobic process of organic fertilizers formation with microbial activities that can be used as a soil amendment [8][9][10]. The end product of composting is humus-like substances that improve the soil's physio-chemical and biological properties [11][12][13]. Composting is a lengthy decomposition process; to accelerate the composting process and reduce nitrogen loss, various additives like ash, fertilizers, phosphogypsum, jaggery, lime, biochar, FGD gypsum, polyethylene glycol, various bacterial strains are often added to it [14,15].…”

Co-digestion of organic biomass mixed with inorganic amendments could have an impact on composting dynamics. Various studies highlighted fertilizers’ role as an additive to lesser the nitrogen loss, while some studies focused on the addition of fertilizers to enhance the efficiency. The changes in carbon, nitrogen components, and humic substances during the organic-inorganic co-compost process were seldom studied. Clarifying these changes might help improve the production process and compost nutrients contents. Thus, this study’s purpose is to investigate the effects of inorganic amendments on compost characteristics, compost temperature, biochemical methane production (BMP), and nutritional contents. The inorganic phosphorous (P), sulfur (S), and sulfur solubilizing agent (SSA) were added to Farmyard manure (FYM) mixed with biodegradable waste (BW), including wheat straw, corn stalks, and green lawn waste. The P and S amended treatments were carried out into two sets, with and without SSA. The mixed feedstocks were added in the insulated RBC composting pit (15 x 15 x 10 feet). The compost material’s moisture content was maintained 50–65% during the entire composting process for optimum waste digestion i.e., the moisture content (MC) of FYM was 82.7% and for BW ranged 8.8–10.2%, while the C/N ratio was found 10.5 for FYM, 74.5 for wheat straw, 83.5 for corn stalks, and 84.8 for lawn waste. At the condition of compost maturity, the inorganic amendments have no significant effect on composted material’s moisture content. The maximum organic matter of 69.7% and C/N ratio of 44.6 was measured in T1. On the 6th day of composting, the temperature reached to thermophilic range (>45 oC) in all the treatments due to aeration of compost increased microbial activities and waste decomposition rate and decreased gradually to mesophilic range (35–45 oC) because the supply of high-energy compounds becomes exhausted. The highest temperature was reached in T4 (58 oC) and lowest in CT (47 oC). The significantly maximum methane of 8.95 m3 and biogas burning was 818 minutes in CT, followed by T1 and T4. The results of this study revealed that P enriched compost is a feasible and sustainable way to overcome P deficiency in the soil as well as in plants and best way to use low-grade P and organic waste material.

“…Compost, green manure, and farmyard manure is a well-established way to enhance OM content in the soil [17,18]. Nutrient availability is low from the applied organic waste, but it also has more variations and imbalance and deficit supply of nutrients to the crop [19].…”

“…Recycling agricultural waste using traditional composting is experiencing protracted composting issues. Because agricultural waste has a high nitrogen concentration, it produces hazardous substances during typical composting, including ammonia (NH 3 ), nitrous oxide (N 2 O), nitric oxide (NO), methane (CH 4 ), and volatile organic compounds (VOC s ) . This review studied the composting of agricultural waste amended with various mineral, organic, and biological additives to enhance the process variables and product quality.…”

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.

“…Due to the lack of cost-effective utilizing techniques, corn straw is generally disposed by burning, leading to severe air pollution and wastage of resources [5][6][7]. In recent years, new techniques have been developed for biofuel or biogas production using crop residue as primary materials [8][9][10]. Unfortunately, due to low productivity and high cost, these techniques have not been widely used in practical production [11,12].…”

A new strategy was proposed to improve the utilization rate of corn straw by making non-ruminant feed products. The corn straw was ball milled, and the crushed straw was subjected to solid-state fermentation. After ball milling, the particle size of corn straw decreased significantly from 4.85 ± 0.07 cm to 10-100 μm, the content of neutral detergent fiber and acid detergent fiber decreased by 1.3% and 3.5%, respectively, and the total soluble sugar content increased by 16.2 mg/g. At the same time, the straw treated by ball milling as substrate could promote the rapid growth of Pediococcus acidilactici R30, the increase of organic acid production and further improvement of other nutrients during solid-state fermentation. In conclusion, the fermented straw products after ball milling could significantly improve the performance of pig feed in terms of digestibility and nutritional value, and better meet the feed needs of non-ruminant animals while saving resources.
