Influence of long-term neglect of liming and P-fertilization, different plowing depths, organic fertilization and crop rotations on soil fertility and yield performance of silty sandy soil.
The long-term experiment D III was set up by Kurt Opitz in 1923 on a newly established test field in Berlin-Dahlem to provide evidence of the mobilization of soil phosphoric acid through purely agricultural measures (greater plowing depth, regular liming) and to investigate the effectiveness of differentiated P fertilization under these conditions. The importance of organic fertilization for humus supply and the yield level of the sandy soil was later investigated by additionally introducing the experimental factor "manure fertilization" in 1939. In 2014 the experiment was uniformly sown to grass

Design period: (1923—2014)

The experiment has undergone several changes. In the original set up, the trial contained six systematically arranged (unrandomised) replications. The three original treatments were tillage, liming and phosphate fertilizer. Plots have been further split to add new treatments for FYM (1939) and crop rotation (1967). Detailed information about the crop rotations and cropping before 1967 has not been found from the published literature, although winter wheat, potatoes and fodder beet have been identified.
