Introduction. According to «Soyuzmoloko» in 2016, Russia's level of self-sufficiency in dairy products amounted to 8 1.5%. By 2020, according to the Doctrine of Food Security of the Russian Federation, this standard should be 90%. The production of commercial milk amounted to 20.7 million tons and increased by 2.8%. Milk productivity of cows increased by 2.1%. Milk processing and finished goods production grew by 1%. The organization of the farming economy of cattle contributes to the implementation of this Doctrine [1. p. 11]. Agriculture in the Irkutsk region is engaged in 190 agricultural organizations, 3,3 thousand farms, 349 thousand personal subsidiary farms, 120 cooperatives [2. p. 40]. The purpose of the study is to organize a farmer economy to produce high-quality meat products and milk products, with the next retail sale in the Irkutsk region market.

As part of fixed assets are farm, cowshed, truck, bulls, land. In the composition of working capital are food, equipment, lining.

Project analysis. The planning of the production of peasant farms is based on production capacity. Production capacities are limited by labor resources, production areas, natural components. The general management of the peasant farm will be carried out by the entrepreneur. The working staff will consist of 3 replaceable basic workers. The salary at the enterprise is time-based. The sales plan is calculated on the fact of receipt of proceeds from the sale of products. The farm will start farming activities from the 1Y. The sales plan is presented in Table 6.

Calculation of depreciation is carried out proceeding from the fact that the service life of a barn and a tractor is 10 years. Depreciation is accrued on a straight-line basis. Depreciation charges amount to 188 000 rubles in year.

The cost of production includes conditionally variable and conditionally fixed costs. Commercial expenses are represented by expenses for the purchase of fuels and lubricants (fuels and lubricants), which are accounted for at constant costs, and management costs in the management salaries.

Formation of the price for production of Individual Entrepreneur. The farmer is based on a costly and market approach. The price covers the costs of production, but does not exceed the price of competitors. Production indicators according to the plan of the economy: indicator milk yield from 1 cow per year - 4400 kg. Conditional variable costs include animal feed. The amount of feed intake is affected by the age of the animals, lactation and weight. The variable costs in accordance with the production plan are presented in Table 7.

The cost of purchasing food increases in accordance with the increase in the herd number from 15 to 56 head of cattle. The farmer sells livestock products. Farmer activity is a profitable type of business, as evidenced by statistics on the breeding of cattle in the Irkutsk region.

The products are fully sold in the agricultural markets of the Irkutsk region. Cattle breeding refers to agricultural activities, so the calculation uses a single agricultural tax (6%), in addition to which mandatory contributions to the pension fund of the Russian Federation and the social insurance fund (30%) are paid. These taxes are included in fixed costs. The need for non-current assets arises in the first year. They are related to the acquisition of agricultural machinery. The total need for non-current assets will amount to 1 880 000 rubles, including: grant funds - 1 500 000 rubles. And own means of the farmer - 380 000 rubles.

In Tables 7-8, reflecting costs, revenue and net profit. According to calculated data, it is clear that from 3Q 1Y to 2Q 2Y, the net profit is negative for months.

Thus, the amount of this profit and will be a need for current assets in 1Y.

The need for current assets of the project will be 340 500 rubles. As a result of unfavorable weather conditions, about 70% of the losses in the national economy fall on agricultural production [10. р. 94]. When analyzing risks, it was revealed that many factors influence the efficiency of work. One of the most important is the incidence of bull-calves, which can lead to the death of animals. The main obstacles that can place project implementation are poor climatic conditions - low yields resulting in a shortage of feed.

Conclusion. The project is based on the organization of peasant farming of cattle and ensuring the quality of meat and milk products. The production program is presented. The project of cattle farm cost-effective and practical to implement.

Аннотация

В полевом опыте, в условиях Смоленской области, на дерново-подзолистой легкосуглинистой почве с различной обеспеченностью подвижным фосфором, изучали действие доз минеральных удобрений на урожайность и качество зерна озимой пшеницы сорта «Московская 39». Наиболее рационально представленные в настоящей статье системы минеральных удобрений применять на фосфатных фонах Рф600 и Рф]200ь созданных посредством внесения фосфоритной муки. На этих фонах были получены наибольшая урожайность и показатели качества зерна при совместном внесении азотно-калийных удобрений с суперфосфатом. Однако наблюдалась тенденция к снижению сырого белка и клейковины в зерне озимой пшеницы при повышении дозы фосфорных удобрений.

Ключевые слова: озимая пшеница, минеральные удобрения, фосфоритная мука, урожайность, качество.

Abstract

The effect of doses of mineral fertilizers on the yield and quality of winter wheat of the "Moscow 39 " variety was studied in the field experiment in the Smolensk region on soddy-podzolic light loamy soil with varying availability of mobile phosphorus. Mineral fertilizer systems, presented in this article, are the most rationally to use on phosphate phone of Rf600 and Rf1200, created by applying phosphate flour. The highest yields and grain quality indicators on these phones were obtained with the joint application of nitrogen-potassium fertilizers with superphosphate. However, there was a tendency to reduce the crude protein and gluten in the grain of winter wheat with an increase in the dose ofphosphorus fertilizers.

Keywords: winter wheat, mineral fertilizers, phosphorite flour, yield, quality.

Во многих регионах России фосфор лимитирует рост продуктивности земледелия. В этой связи необходимым у словием его повышения является создание в почвах оптимального фосфатного уровня [1, С. 31], [2, С. 28], [3, С. 166]. В условиях дефицита фосфора в нашей стране представляют интерес исследования наиболее эффективного использования фосфоритной муки, как самого дешёвого, низкозатратного, технологически очень простого фосфорного удобрения, которое по своей эффективности близко к действию суперфосфата на урожай сельскохозяйственных культур [4, С. 88], [5, С. 99], [6, С. 31].

Длительное применение фосфоритной муки приводит к существенным изменениям в почвенном поглощающем комплексе, следствием чего является обогащение почвы подвижными формами фосфора и питательными веществами, в частности обменным кальцием и магнием, а также кремнием, натрием и микроэлементами [7, С. 57], [8, С. 25]. Несмотря на исключительную актуальность процесс формирования фосфатного уровня почв до настоящего времени пока ещё мало изучен и требует дальнейшего уточнения.

Цель работы. Разработать систему наиболее эффективного применения разных видов фосфорных удобрений на почвах с различным уровнем содержания подвижных фосфатов для условий Центрального района Нечернозёмной зоны.
