This article explores the possibility and effectiveness of using chicken manure as an organic fertilizer “Soil Improver (UP-1)”, obtained by using the drug “Mephosphon” for growing crops and producing organic products. Under laboratory conditions, experiments on the fermentation of manure were carried out, measurements of the ammonium ion were carried out, and the levels of toxicity of extracts from chicken manure were studied using test objects Ceriodaphnia affinis and Paramecium caudatum, followed by determining the hazard class of chicken manure. Field tests were carried out on soddy-podzolic medium loamy soils of the Pestrechinsky district near the village. Khodyashevo. The total sowing area was 72 ha (1 ha - background, 19 ha - control, 52 ha - experimental field). The background field was without chicken manure, the control field was composted chicken manure, and the experimental field was with UP-1 fertilizer. 130 tons of chicken manure were applied per 1 ha. Organic compost “Soil Improver (UP-1)” was obtained from poultry wastes of OJSC “Agrofirm “Ak Bars – Pestretsy” branch of poultry farm of Pestrechinsky district of the Republic of Tatarstan. Biometric analysis of the growth and development of winter wheat was carried out from April 29 to June 1, 2021. The stem height of plants in the experimental variant is 14% higher than in the background, and 6.8 - 8.9% higher than in the control variant. According to the average weight of the raw and dry stem, the experimental group has the advantage, while surpassing the control in all periods of the growing season by 0.1-2.9 pieces. and 0.1-1.4 pcs. The obtained experimental data show that the use of organic compost “Soil Improver (UP-1)” as a fertilizer in the cultivation of winter wheat provides a higher yield compared to the background by 56.6%, and compared to the control by 55.5% . At the same time, 146.64 tons of organic winter wheat were obtained

The article presents the possibilities of obtaining useful products from poultry and oil industry wastes using Mephosphon biologically active agent. The use of an aqueous solution of the Mephosphone preparation in ultra-low concentrations (10−6–10−8%) allowed obtaining the Compost UP-1 product from chicken manure and the Meliorant product from drilling waste. The Compost UP-1 belongs to the 4th hazard class in terms of physico-chemical and sanitary-biological characteristics, and the Meliorant product in terms of pollutant content belongs to the 5th hazard class. Studies on the influence of useful products derived from waste were carried out in the field in the experimental fields of the Laishevsky district of the Republic of Tatarstan. The Compost UP-1 and Meliorant products were introduced during pre-sowing cultivation in an amount of 26 t/ha and 1.3 t/ha, respectively. For comparison, during the research, reference plots were organized (Reference). The seeds were spring wheat of the Yoldyz variety (Compost UP-1) and Idelle (Meliorant). The analysis of growth and productivity indicators of plants grown in different areas showed that the use of the obtained products improved soil fertility: the introduction of the Meliorant product optimizes soil pH, activates mass transfer processes, and the introduction of the Compost UP-1 product increases the content of nutrients (N, P, K). So at the tillering stage in the section with Compost UP-1, the average phytomass per unit length of plants was 1.8 times higher than in the Reference. The use of Compost UP-1 leads to a significant improvement in grain quality: the mass fraction of protein increased by 32 %, vitreous content by 60 %, and the content of crude gluten by 34 %. Productivity increased and amounted to 42 kg/ha, which is 14 kg more than in the Reference. The use of the Meliorant also activated the growth of plants, and led to an improvement in the quality of grain.

The article considers utilization of organic waste from poultry farming being an urgent problem of agriculture. Leaders of large poultry farms are interested in using low-cost recycling schemes aimed to process waste into safe products in a short time. This paper considers the possibility of using an organic fertilizer “Soil Improver (UP-1)” obtained by processing poultry waste by using a biologically active additive Mefosfon, which is a melamine salt of bis (oxymethyl) phosphinic acid. Field tests were carried out in 2019-2020 on the lands of OAO “Agrofirma “Ak Bars-Pestretsy” being the branch of the Poultry farm of the Pestrechinsky district of the Republic of Tatarstan. The object of the study was the recognized variety of soft winter wheat “Scepter” ES (elite variety). The rate of application of chicken compost and organic product UP-1 in the control and experimental plots was 56 tons per 1 ha. The experimental data show that wheat cultivated with the application of UP-1 compost was distinguished by higher rates of field germination (increased by 13 %); the length of secondary roots was 11.2 % greater compared to control. The grain produced in this variant had higher hardness (control – 62 %, UP-1 – 72 %) and the quality of crud gluten (74.0, 78.0 %, respectively), the yield of winter wheat grain – by 0.06–0.12 t/ha (1.2–2.5 %), which indicates the feasibility of using fertilizer from poultry manure in crops cultivation.

The article presents the results of the practical application of products obtained from waste from poultry farming and the oil industry using the biologically active drug “Mefosfon”. Field tests using an aqueous solution of “Mefosfon” at extremely low concentrations (10-6 - 10-8%) made it possible to obtain “Kompost UP-1” product of IV hazard class from chicken manure, and “Meliorant” product of V hazard class from drilling waste. Field studies to study the effect of products on spring wheat growth were carried out in the experimental fields of the Laishevsky district of the Republic of Tatarstan. “Kompost UP-1” and “Meliorant” were introduced under pre-sowing cultivation in the amount of 50 tons per hectare and 1.3 tons per hectare, respectively. For comparison, control plots were organized (Control). The seeds used were spring wheat of Yoldyz variety (“Kompost UP-1”) and Idelle (Meliorant). Analysis of growth and productivity indicators of plants grown in different areas showed that the application of “Meliorant” optimizes soil pH, activates mass transfer processes, and the application of “Kompost UP-1” helps to increase the content of nutrients (N, P, K). At the stage of tillering of plants in the area with “Kompost UP-1”, the average phytomass per unit length of plants was 1.8 times higher than in the control. The use of “Kompost UP-1” leads to a significant improvement in grain quality: the mass fraction of protein increased by 32%, vitreous content by 60%, and the content of crude gluten by 34%. Productivity increased and amounted to 42 kg/ha, which is 14 kg more than in the control.

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.
