Microbiological study of effects of solid organic waste (chicken droppings and sheep manure) decomposed in the soil used for Pisum sativum cultivation

摘要

Organic agriculture uses biofertilisers which can increase yields and enhance qualities of foodstuffs. This present work examines the composting of chicken droppings and sheep manure and their effects on Pisum sativum cultivation. The biodiversity of chicken droppings' filamentous fungi is different from that of sheep manure. In addition, filamentous fungi associated with the decomposition of chicken droppings in the soil were mainly pathogenic and phytopathogenic fungal species. The study has shown that sheep manure is a good biofertiliser to improve crop yield and quality. The use of chicken droppings as biofertilisers without maturation may cause risks to the environment and public health.
