In recent years, the interest in subsoil has increased, since it can hold immense reservoirs of nutrients, organic matter and water. The subsoil can therefore provide important ecosystem services for the agricultural production system and beyond. This paper assesses the sustainability of two subsoil management measures with regard to the delivery of soil-related ecosystem services: a) the cultivation of deep-rooted pre-crops (biological approach) and b) stripwise mechanical subsoil loosening in combination with the incorporation of...

The aim of the study was to determine the effect of belowground plant-derived carbohydrates on P uptake, P concentrations and enzymes activities related to P mobilization in roots, ectomycorrhizas and soil and on the abundances of P-related genes in soil bacteria. We report data from a girdling experiment in two temperate beech forest with contrasting soil phosphorus concentrations. We used soil cores and the fractions of the organic layer and mineral topsoil separately one and...
