Abstract
Abstract The objective of this study was to understand how eight decades of tillage affected soil element dynamics. We measured soil chemical properties and the 14C:12C ratio (Δ14C) of organic carbon in one of the oldest cropland experiments in Europe with different levels of phosphorus addition. So...
