Abstract The results of the study of the impact of long-term use of different norms of fertilizers and fertilization in field crop rotation on the density and permeability compilation podzolic chernozem vazhkosuhlynkovoho Right-Bank Forest-Steppe of Ukraine. In the stationary experiment the Department of Soil Science and Agricultural Chemistry, which founded in 1964 with mineral, organic and organo- mineral fertilization in crop rotation systems at three levels batteries of field crops, the influence of fertilizers on the density and permeability of the soil at the link rotation pea - winter wheat - corn silage. Found that with increasing standards of fertilizers at the beginning of growing season growing peas as compared to control density and reduced permeability of the soil. Organic fertilizers positively affect agrophysical soil properties, particularly at higher standards manure 18 t/ha in the 20-30 cm layer density versus controls decreased by 0.07, but against the triple standards of fertilizers to 0.13 g/cm3, permeability for the first hour of study increased respectively by 220 and 210 mm. For organo-mineral system of organic fertilizer reduces the negative impact of mineral fertilizer and maintain density and permeability podzolic chernozem optimal parameters. During the growing season as a result of natural and anthropogenic degradation occurred deformation valuable agronomic fraction of the structure and density and soil permeability with depth, and reducing its permeability, which can be explained by the processes of dispersion of the colloidal fraction.
Key words black soil ashed vazhkosuhlynkovy, agrophysical properties of soil, taking the density, permeability, organic fertilizer, fertilizer
