Data underlying the publication: Positive effects of various organic amendments on soil life in a multi-year field experiment

In this study we investigated the microbial and nematode soil life, indicators for overall soil health, after application of different organic products, and compared this to the use of different dosages of artificial fertilizers and an conventional treatment over three years. In the fourth year we studied the dynamics of the same parameters over one growing season. Although crop yield was lower compared to the conventional treatment, several products, especially a bokashi and fresh clippings, enhanced soil bacterial and fungal abundance as well as the abundance of nematodes. These effects were stable over several years. Moreover, we could demonstrate that timepoint of measurement over the growing season did not affect the observed effect of the treatment in spite of strong temporal fluctuations. <br>Two datatsets were used in this study. One contains the phospholipid fatty acid (PLFA) measurements and soil nematode counts and indices of one sampling timepoint each in 2021, 2022, and 2023. Four randomized blocks of plots treated with one of the 11 products were sampled and product treatment was the same for each block over the years. All treatment details and timepoint of sampling are described in the publication. The other dataset contains the PLFA measurements and nematode counts and indices of several sampling timepoints in 2024. Samples for PLFA were taken at 7 timepoints. Samples for nematodes were taken at 4 timepoints. Moreover, in 2024, only a subset of 4 product treatments was sampled.
