Summary
High nitrous oxide emissions are reported in literature when grass-clover is mulched in stockless farming systems. In our study, we measured similar emission rates especially after intensive rainfall when shoot biomass of grass-clover is transferred to maize and celeriac as a source of plant available nitrogen. Inefficient use of nitrogen bound in this mulch may furthermore result in nitrate leaching, especially if harvest is late and bare fallow over winter unavoidable.
