Influence of long-term fertilization on soil and endophytic microbial communities
Published data were used in a project that was focused on the influence of long-term fertilization treatment on microbial communities in soil and potato tubers. Sample collection was performed in September 2017 at two locations called Humpolec and Suchdol, both in the Czech republic. Since 1996, the field-plots have been periodically fertilized with sewage sludge, sewage sludge, cow manure, NPK. Unfertilized soil (CF) was used as a negative control. Potato (Solanum tuberosum L.), winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.) have been rotated in these fields every three years, respectively. According to typical agricultural practice, organic fertilizers (MF, SF, SF3x) were applied on the soil before potato plowing, while chemical fertilizer (NPK) was applied regularly throughout the rotation cycle. The application rate of fertilizers was calculated based on the total nitrogen input into the soil for the whole three-year rotation period.
