METHOD OF CONTROLLING STATE OF GROUND WATERS DURING LIVESTOCK WASTE IRRIGATION

摘要

FIELD: ecology.;SUBSTANCE: method includes ecological monitoring of ground waters using wastewater for the irrigation of lands by sprinkling machines to cultivate perennial grasses. The method includes irrigation fields for utilisation of manure-containing flows in the formed irrigation pattern. For this purpose, observation hydroregime wells are arranged for each individual field at the boundary on the side of the open bounded reservoir and the inflow of drainage water into it. And the measurement is carried out in the site at the boundary of the water bearing stratum, the heterogeneity of the soil cover and the profile. In the study of ground waters samples are taken twice - prior to the irrigation season and after the irrigation season. In this case, the studies of the taken samples are carried out in the agrochemical laboratory by analytical analysis to determine the chemical composition of the water bearing stratum, the values of biochemical values such as pH, NH₄, N_org, P₂O₅, K₂O, Ca, Mg, Na, C₁, SO₄, the quantity of mobile potassium, phosphorus and nitrogen nitrates are measured. Based on the results of the biochemical analysis prior to irrigation and after irrigation of the taken samples from the water bearing stratum for each regime well, the ecological safety of the utilisation of livestock waste is estimated by the content of biogenic elements. In this case, the measurement of the level and values of the biochemical indicators of the water bearing stratum is carried out in the regime wells, the top of the pipe of which is placed above the ground surface and the pipes are placed inside the metal casing in the form of a pipe with a lid.;EFFECT: method makes it possible to estimate the degree of ground water contamination for each site from the use of liquid manure from industrial livestock enterprises.;2 cl, 2 dwg, 1 tbl
