Reduced nitrogen losses from drained temperate agricultural peatland after mineral soil coverage
Draining peatlands for agriculture induces peat decomposition, subsidence, and carbon (C) and nitrogen (N) losses, thereby contributing to soil...
-
Nitrogen supply by cut-and-carry biomass for vegetable crops and subsequent cereals
Green manure legumes represent an important nitrogen (N) source potentially reducing the need for fertilizer inputs. Organic vegetable production...
