The effect of cattle liquid manure fertilization on alternating grassland and some groups of soil mesofauna

The influence of different doses of cattle liquid manure, with or without the VG agent, on the crop of green forage of alternating grassland, and on the density of mites, springtails and enchytraeids was investigated. Fertilizer without VG increased both the crop and density of mites, springtails and enchytraeids. The mites reacted positively to higher dose of liquid manure, especially with 2%VG (bactericidal). Liquid manure increased the density of Oribatida, especially the lower dose with and without 1%VG (fungicidal). Springtails responded to liquid manure positively, and their density increased with the doses of fertilizer, especially with 1%VG. The enchytraeids reacted positively to liquid manure with and without 2%VG, while fertilizer with 1%VG reduced their density, compared to the control plot. Fertilizer also caused the migration of some enchytracids from the soil to lower parts of plants, compared to the control plot.
