Repeated use of green-manure catch crops in organic cereal production - grain yields and nitrogen supply [PDF]
, 2011 By restricted access to manure, nitrogen (N) supply in organic agriculture relies on biological N-fixation. This study compares grain yields after one full-season green manure (FSGM) to yields with repeated use of a green-manure catch crop.
