Le résumé fourni par la source

Field experiments conducted at the Centre of Estonian Rural Research and Knowledge evaluated six leguminous green manure crops grown as independent crops within an organic crop rotation. The pre-incorporation biomass (dry matter t/ha) and the corresponding plant nutrients (N, C, P, K kg/ha) were determined. The fertilizing value of green manure was assessed on spring cereals (barley, spring wheat, oats, two varieties of each) in the year following incorporation, based on the changes in yield, yield quality and thein contribution to the realizable market value per hectare. The experimental results showed that all green manure species significantly increased spring cereal yields per hectare and improved most of the quality indicators, to an extent that allowed spring wheat and oats to be marketed as food grain, thereby enabling a higher sale price. Variety choice was an important factor. Spring wheat and barley responded well to red and pink clover used as green manure, with yield increases of approximately 60%, while annual, biennial and perennial legumes sown as green manure had a similar fertilizing effect on oats, resulting in yield increase of 30–40%.
