The article considers the accelerated reprocessing technology for recycling pig manure into organic fertilizer. Today, closely relevant is the matter of environmentally friendly technologies for cattle manure utilization. Export of wastes in its pure form to agricultural land cannot be applied, because disease causing and chemical compound penetrated the soil, entered the groundwater and contaminated many water sources. Experiments for the accelerated reprocessing of the pig manure into organic fertilizer were conducted on the basis of PCF No. 2 of the APC "Maryanskaya" in the Krasnoarmeisky district. With the aim of eliminating the filtering of pollutants in soil and groundwater, the experiment was performed in a concreted area, located within a farm. For the test, we used pig manure of animals, whose age was 2-8 months. The total weight of used manure was 40 t. The accumulation of manure was carried out in containers, containing 4 tons; the total time for the accumulation of necessary amount of manure for 2 months. Comparing the quality of compost obtained by the proposed technology recommended for industrial applications, control, we found differences in the chemical and biological properties. Overall, the conducted experiment has allowed to establish that the best option, given the speed of the flow of chemical and biological processes, demands environmental protection, is composting manure with straw, adding a biological product "Tamir" at the rate of 0.5 l/t. The Obtained results are comparable with data of previous years and indicate the possibility of reducing the quantity of a biological product from 1 to 0.5 l/t of waste without reducing the efficiency of the process of accelerated decomposition of nitrogenous organic compounds

We have conducted a research on the poultry farm of the commodity farm of the educational and experimental farm Kuban of the Kuban State Agrarian University. The chemical analysis of various organic fertilizers is considered in the article. Also agrochemical characteristics of organic fertilizers are given. The composition and properties of the bird droppings of the farm under study were determined for comparison with other organic fertilizers: manure of cattle and pig manure. Since straw is used as the main moisture-absorbing material for composting in the farm under study, straw analyzes were carried out in terms of chemical composition and nutritional content. A chemical analysis of the content of plant nutrients in straw has been carried out. Bird droppings is valuable, a fast full fertilizer. Of all organic fertilizers, bird droppings are the most valuable, both in nutrient content and in their accessibility to plants. The nutrient content in the litter varies depending on the species of the bird, the breed, the age, the method of keeping and feeding, the type of feed and other factors. The chicken manure contains morephosphorus, nitrogen and potassium, than manure of cattle and pigs. The advantage of organic fertilizers in comparison with mineral fertilizers is their long after-effect. As fertilizer a bird droppings surpasses manure at 8-10 times and almost don't concede to equal amount of nutrients of mineral fertilizers by action on productivity of cultures. The norm of introduction of bird droppings is up to 30 times lower, than norm of introduction of manure. Agricultural areas where introduction of organic fertilizers, the list of crops under which fertilizers are introduced were considered. The received results confirm the value of organic fertilizers (bird droppings), and their application enriches the soil with necessary nutrients, increases productivity and quality of grown-up crops

The results of the study farm «Zavet Ilyicha» JSC, Leningrad district of Krasnodar region, are presented in article to study the role of rolling phosphorus in soil samples, organic fertilizers and grain output of winter wheat. We examined the relationship between the content of phosphorus in the soil and fertilizers are introduced and subsequently with the quality of the harvest of grain. To receive high harvests of crops, primarily need adequate amounts of phosphorus in soils in an accessible form. The next important step is the use of different fertilizers (mineral and organic) under crops. Without the use of fertilizers cannot return key for plants of nutrients, such as phosphorus, nitrogen and sodium in the soil, since agricultural products makes the nutrients. What dose of fertilizer use and profitable forms of these fertilizers, solves every household depending on culture, soil, climate and economy. We received during the research the following results: for 4 year average contents of phosphorus in soils of agro-landscape in General, au pairs amounted to 27.2–31.4 mg/kg. Average levels of phosphorus in the soils crop rotation fields amounted to 26.9 and 30.9 mg/kg. Maximum values amounted to 115.0 mg/kg, while the minimum is about 3.0 mg/kg. Also conducted analyses on the contents of rolling phosphorus in manure polupereprevshem pigs and cattle. Marked by a very significant gap in content of phosphorus, which is associated with significant differences in their feeding. In grain of winter wheat for 4 years, phosphorus content accounted for at an average of 3.41 g/kg; minimum and maximum performance from 2.35 to 4.47 g/kg, in 2012. Compared with 2012 phosphorus concentrations in grain of winter wheat has gradually increased to 2015, and accounted for 3.47 g/kg with minimum and maximum thresholds ranging from 2.05 to 4.89 g/kg
