INFLUENCE OF MANURE STORAGE AND PROCESSING TECHNOLOGIES ON THE CHEMICAL PARAMETERS OF WATER

Abstract

Studies to study the impact of various options for storing and processing manure on the content of chemical compounds in the catchment area of farms were carried out in two farms in the Kyiv region with loose housing of cows. At AIS LLC, animals are kept in an easy-to-collect room, and manure is stored in a room with a deep, long-changing straw litter separately from waste from the milking and dairy block. In Terezine ALC, cows are kept in an easily assembled room with boxes. At the same time, manure is stored and processed in a bioreactor-fermenter. Water sampling for analysis on farms, springs within a radius of 1 km from farms, and in the nearest natural reservoirs (Ros and Protoka rivers, Bila Tserkva district, Kyiv region) was carried out during the second decade of September 2021. With the option of storage and processing of manure in a bioreactor-fermenter, the concentration of chlorides was 16.36 mg/dm3 higher compared to the option of storage and processing of manure in a room with deep, long-lasting straw litter. The sulfate and phosphate content was also higher – by 11.97 and 0.01 mg/dm3 Under. The content of chlorides, phosphates, and sulfites in water samples taken within a radius of 1 km from farms was 17.22 higher than the option of storage and processing of manure in a bioreactor-fermenter; 0.02 and 11.27 mg/dm 3. The content of chlorides, phosphates, and sulfites in drinking water samples taken from drinking bowls for animals was also slightly higher for the option of storage and processing of manure in a bioreactor-fermenter by 17.22; 0.02 and 12.91 mg/dm 3. In samples of drinking water taken from drinking bowls for animals under the option of storage and processing of manure in a room with deep, long-changing straw litter, The ammonium content was slightly higher than the indicators obtained from the farm where manure processing takes place in a bioreactor-fermenter (by 0.05 mg/dm3). So, with the option of storing and processing manure in a room with a deep, long-lasting straw litter, wastewater after washing milking equipment does not get into organic waste but settles and is disposed of. With this technology, the concentration of chemical compounds in the drinking water of the farm and the springs used by the population within a radius of 1 km from the research object and in the nearest natural reservoirs with running water is lower than in the case when the water after washing the milking equipment enters the general storage of manure (bioreactor-fermenter).
