Earthworm abundance, biomass and species composition in mixed and stockless organic farming systems: evidence after a six-year crop rotation

Perennial legume-grass leys and organic fertilizers are essential for soil fertility in organic farming. In stockless systems, inputs such as compost or biogas residues replace livestock manure, but their effects on soil fauna remain unclear. This study evaluated earthworm abundance, biomass and species composition in three farm types: mixed farm (MF) with two-year leys and […]
