The search for technical means and methods for the use of liquid and solid fractions of compozed organic fertilizers to improve soil fertility and technological equipment is valuable and necessary scientific material. The problem of using the liquid residue of the organic matter after fermentation in the biogas plant is to limit the periods of permitted entry into the field, and as a consequence, requires the need for buildings for the accumulation of raw materials, and high productivity
Of the means for its preparation and distribution by field, or application to the soil. Along with the positive indicators of a potential fertility of the soil, there are a large number of indicators that adversely affect the environment. This: pollution of natural reservoirs; Air pollution. Alteration of microbiological activity of soil; Deterioration of the phytosanitary condition of soil; Microbiological and bacterial contamination of the soil; Soil contamination with heavy metals.
The research program included determining the hydrological properties of the soil in relation to different fractions and determination of sorptive soil capacity on nitrate and ammonium nitrogen. The definition and calculation of filtration properties was ensured by the A minimum of water absorption in model diagrams of up to 700 cm3 and a constant pressure of the water column on the surface of filtration (7 cm). Determined coefficients of the distribution of adsorption and diffusion. The method of measuring the distribution coefficients of organic compound is by a method of eluate wave or frontal filtration in a column.
The original method of calculating indicators was developed. The obtained results showed the efficiency of method by definition of quantitative estimation of sortation of nitrate and ammonium nitrogen of liquid and solid fraction, allows to estimate mobility by coefficient of diffusion and distribution. Conclusion that distribution and distribution of compounds in The top layer of soil should be 25...50 cm, which prevents filtration to the groundwater level, with a norm application of 55...75 t/ha. This will get the fertility of low-productive soils-up to 70-80 с/ha of wheat.
