Summary

Researchers studied how periodic water supplementation affects the enzyme activity and fungal communities in sheep manure composting on the arid Qinghai-Tibet Plateau. More frequent watering improved fungal metabolic function and enzyme activity, speeding up decomposition. These findings help optimize composting protocols in dry climates for better agricultural waste management.

The dry climate characteristics of the Qinghai-Tibet Plateau will seriously affect microbial metabolism during composting. In this study, we aimed to investigate the effects of regular water supplementation on the fungal and enzymatic activities of sheep manure composting in the Qinghai-Tibet Plateau. The experiment set up the treatments of water replenishment once every 7 days(T2) and 3.5 days (T3) days, and no water supplementation was used as the control (T1). The results showed that regular water supplementation increased the activities of various enzymes during composting, and the activities of protease, cellulase, peroxidase and polyphenol oxidase in T3 were higher than those in T2. Regular water supplementation increased the relative abundance of Remersonia and Mycothermus, which were significantly positively correlated with the germination index, and degradation of organic components. Regular water supplementation could enrich fungi carbohydrate, protein, and nucleotide metabolisms, and T3 had a better effect. A redundancy analysis showed that environmental factors could significantly affect the fungal community; among them, moisture content (76.9%, p = 0.002) was the greatest contributor. In conclusion, regular water supplementation can improve the key enzyme activities and fungal metabolic function of sheep manure composting, and water replenishment once every 3.5 days had the best effect.

Effects of turning frequency on fermentation efficiency and microbial community metabolic function of sheep manure composting on the Qinghai–Tibet Plateau

Researchers tested five different turning frequencies during sheep manure composting on the high-altitude Qinghai-Tibet Plateau, finding that turning every two days produced the best compost quality — including highest temperatures, best seed germination rates, and most active microbial metabolism. The findings offer practical guidance for improving agricultural composting practices in cold, high-elevation environments.

Effects of biochar carried microbial agent on compost quality, greenhouse gas emission and bacterial community during sheep manure composting

Researchers found that combining biochar (a carbon-rich soil amendment) with beneficial microbes as a composting additive significantly improved compost quality while cutting methane, nitrous oxide, and ammonia emissions by 65%, 69%, and 42%, respectively, during sheep manure composting. The approach offers a practical way to make agricultural waste management both more productive and lower-emission.

Ecological and Microbial Processes in Green Waste Co-composting for Pathogen Control and Evaluation of Compost Quality Index (CQI) Toward Agricultural Biosafety

Researchers studied the process of co-composting green garden waste with sheep manure under semi-arid conditions in Morocco. They found that the composting process effectively eliminated pathogens, including harmful bacteria and parasite eggs, while producing quality compost. The study demonstrates that properly managed composting can turn organic waste into a safe soil amendment for agriculture.
