In article the current problem of agriculture – utilization of livestock waste is considered. Heads of the enterprises are interested in introduction of the low-cost schemes of utilization allowing to process into short terms waste in safe products. In this work it is considered the possibility of processing of waste by means of the Mefosfon dietary supplement representing melamine salt encore (oxymethyl) of fosfinovy acid. The possibility of acceleration of process of "maturing" of navoz due to stimulation of microbic activity in waste is supposed. Results of a research of fermentation of a bespodstilochny chicken dung and dung are given in an opilochny laying with Mefosfon's addition and Baikal-EM1. The intensity of process of biodestruction of nitrogen-containing connections was estimated on change of maintenance of ions of ammonium (NH4+) which was determined by a photocolorimetric method by Romashkevich. Acceleration of processes of ammonification at addition in medicine Mefosfon waste is shown. Reduction of concentration of ammoniyny nitrogen in the samples processed by Melafen in combination with the microbic medicine Baikal-EM1 up to 30% in 4 months of an experiment is recorded. Biotesting of experimental tests has shown decrease in toxicity of a dung with III to the IV class. At the same time it was noted that the negative impact on hydrobionts of the tests processed by medicines was lower than 1,5-2 times of control tests without processing medicines.

The laboratory vegetative chronic experiments, on the example of spring wheat, showed that reclaimed drill cuttings can be used for deoxidizing (liming) acidic soils, increasing the biomass yield in growing agricultural crops. Doses of drill cuttings providing long-term maintenance of optimum acidity of investigated soils are defined.

In connection with the necessity to speed up the composting process and preserve the nutrients in chicken droppings, this paper considers the possibility of its processing with the help of the biologically active additive “Mefosfon”, the preparations “Gorynych”, “Tamir”, “Udachnuy”, “Doctor Robik” and hydrogen peroxide . The object of the study was the droppings-free chicken manure of the III danger class of “Yaratel’ poultry farm of “Ak Bars Poultry Production Company” branch. The experiments were carried out in the open air in 50 liter insulated polyethylene containers for 2/3 filled with chicken droppings for 45 days (July-August 2018). The doses of the drugs being applied were determined by the instructions for their use or by the results of previously conducted experiments. Control served as a litter without drugs. When conducting model tests, the temperature of the substrate was monitored, the smell level of the test substrate, the initial and final humidity of the chicken manure, the presence of pathogenic microflora in the resulting product were determined. Recycled chicken droppings in all experimental variants and control belonged to the IV class of danger to the environment. Microbiological analysis carried out at the end of the experiment showed that, in the variant containing “Mefosfon” preparation, the content of enterococci and coliform bacteria was the lowest and amounted to 4% and 2%, respectively, of the final content in the control samples, indicating the promise of using “Mefosfon” to reduce the time of maturation and neutralization of chicken manure.
