Compost with spent mushroom substrate and chicken manure enhances rice seedling quality and reduces soil-borne pathogens

Abstract

This study was carried out to determine the impacts co-compost of Pleurotus geesteranus spent mushroom substrate and chicken manure (SMC) on seedling quality, rhizosphere microbial characteristics, as well as fungal pathogens in rice seedling substrates. Results showed that incorporating SMC within the substrate, especially 50% volume (R2), increased rice seedling growth and vitality without external fertilization at the seedling growth stage. Moreover, SMC amendment increased microbial activity, and promoted rice seedling recruitment of plant growth-promoting rhizobacteria (PGPR) and fungi (PGPF), and signi cantly reduced the abundance of pathogenic fungi, especially Magnaporthe grisea, and thus reducing soil-borne diseases. It is conducive to the sustainable development of cultivated land and agricultural waste recycling.

Application of microbial agents in organic solid waste composting: a review

“…At present, ultra-low-temperature composting technologies for OSW treatment are still in the exploration stage. 91,94 Although it is still in the research stage and faces some challenges, ultra-low-temperature composting has great potential and development prospects in colder climates. As the research field progresses, ultra-low-temperature composting can be improved and optimized, and it is expected to play a greater role in solving the problems of OSW treatment if it can be combined with other technologies.…”
