Long‐term rotation diversity and nitrogen effects on soil organic carbon and nitrogen stocks

Autor: Marty R. Schmer, Virginia L. Jin, Brian J. Wienhold, Sophia M. Becker, Gary E. Varvel

Publikováno v: Agrosystems, Geosciences & Environment, Vol 3, Iss 1, Pp n/a-n/a (2020)

Abstract Understanding the impacts of long‐term fertilizer management and rotation diversity on soil C and N is needed under a changing climate. The objective of this study was to evaluate the effects of N fertilizer level and crop rotation diversi
