Partial substitution of chemical fertilizers with maize straw: Seeking long‐term improvement of rice yield by raising quality indicators of a red paddy soil
Abstract:Straw application increases crop yield, but the underlying mechanisms of strawsubstitution for chemical fertilizer on yield is not completely understood. We hypothesized that straw application improves crop yield by improving soil quality. In order to clarify how partial substitution of chemical fertilizers with maize straw affects soil properties and the specific contribution of soil properties to double-cropping rice yield, we selected a long-term positioning test station operated since 1982 and designed thr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
