Method of obtaining pure organo-mineral fertilizer and its ecological investigation of the influence on soil fertility

Abstract

The article discusses the soil-improving properties of an environmentally friendly organo-mineral fertilizer (OMF) obtained on a scientific basis at the Institute of Chemistry of the Academy of Sciences of Turkmenistan. The main goal of the study is to obtain an environmentally friendly OMF from chicken manure, which accumulates in large quantities on poultry farms and pollutes the environment, as well as to study the effect of the resulting fertilizer on the humus composition of the soil. Broiler chicken manure, microbiological preparation Nourivit Plus and phosphorite ores from the deposit of the Magdanly-Kugitan region of the Durnaly site were used as raw materials and their chemical compositions were determined (humidity, ash content, total organic matter, total nitrogen, phosphorus, and potassium and pH environment). The composition of bird droppings was found to contain a sufficient amount of organic substances and such important nutrients as nitrogen, phosphorus, and potassium. Under laboratory conditions, a scientific method for obtaining an environmentally friendly OMF was studied. Chicken manure used as raw material was neutralized from weed seeds and helminth eggs. Processing on the basis of waste-free technology of waste generated in poultry farms, an environmentally friendly, cost-effective, soil-improving OMF was obtained. The soil-strengthening properties of the obtained OMFs were studied at the Turkmen Agricultural University named after SA Niyazov on 3 plots of agricultural land measuring 1 x 6 meters. Samples were taken for analysis from each of the 3 soils before and after the application of OMF. An agrochemical analysis of the soil and a quantitative analysis of substances soluble in it were carried out. As a result, the elemental and humus composition of soil samples was determined before and after fertilization, and as a result it was proved that it is possible to increase the amount of humus in the soil from 0.12% to 2.17%.
