Yields and greenhouse gas emissions of cultivation of red clover-grass leys as assessed by LCA when fertilised with organic or mineral fertilisers.

Summary

Red clover-grass leys were fertilized with cow manure or with chemical fertilizers. The yields were lower with organic fertilizers, but nevertheless the GHG emissions were lower per tonne of biomass in organic than in conventional conditions, even when the extra need for cultivation area to gain equal amounts of yield was considered. Results of a 4 year field experiment in Southern Finland.
