The article titles the role of mineral nutrition in the formation of the potato crop of Aroza variety on gray forest soils. During the research years the highest tuber yield on average was obtained 22.56 tons per hectare while treatment by ZHUSS -1 for the treatment of tubers before planting and ZHUSS -2 for conjunction with foliar fertilizers at a dose N150, P150, K150. The yield increased in this variant to 12.89 tons per hectare. The significant fluctuations in productivity of potato Aroza variety were revealed on gray forest soils due to climatic factors. In 2010 dry year the yield ranged from 7.10 tons per hectare up to 12.10 tons per hectare against 80 tons per hectare of organic fertilizers. In humid provided 2012 year, it amounted up 11.43 tons per hectare to 28.87 tons per hectare in the way of application of ZHUSS-1 for the treatment of tubers before planting and ZHUSS-2 in conjunction with foliar fertilizers at a dose N150, P150, K150. 16.90% of nitrogen, 8.27% of phosphorus and 20.03% of potassium were used from the potato plant soil. The fertilizer, depending on the dose were introduced at the following amount: 43,05-43,74% of nitrogen, 15,68-18,06 % of phosphorus, 70,05-75,26 % of potassium. As for the organic fertilizer, the plants have learned 17,34-20,28% of nitrogen, 15,19-17,38% of phosphorus and 25,68-31,31% of potassium. Despite the increase in costs with increasing doses of fertilizers, the highest net income 73001 rubles per hectare and the level of profitability - 106.65% were obtained at the option of applying ZHUSS -1 for the treatment of tubers before planting and ZHUSS -2 in conjunction with foliar fertilizers in N150, P150, K150 dose . In this version there was the lowest cost - 3034 rubles per ton.

High Yielding Varieties

Realization of the potential yield of potatoes at the level of 30-40 t / ha of tubers in a forest of the Middle Volga is only possible when using high-yielding varieties for planting, as well as science-based agricultural technology of their cultivation. We examined the role of area and balance of mineral nutrition in the formation of the potato harvest of two maturity groups: early maturing Vineta and medium-maturing Kurazh on gray forest soils. In the course of our research we found that these varieties are highly productive and to create optimal conditions for the background and the area of power plants in the Middle Volga steppe realizes its potential productivity. The possibility of producing tuber crop varieties was determined: Vineta 30-35 ton per hectare, Courage - 35-40 tons per hectart.

The results of long-term research on the influence of main indicators on their agro-resource potential are summarized on gray forest soils of the upper Volga region. For the conditions of the Vladimir Opolie, the probable yield of biomass and the main products of field crops were calculated at different coefficients ofphotosynthetic active radiation (FAR) use. Calculations of the main product yields are made taking into account the distribution of biomass to by-products and crop-root residues. For field crops of the studied crop rotations, the coefficients of precipitation utilization are estimated. They varied from 44 to 71%, depending on the crop rotation culture. On the slope of the southern exposure when cultivating winter cereals and perennial grasses, the main moisture losses were observed in the spring during snowmelt, when growing spring crops and potatoes, they were close in the autumn and spring periods. The sizes of moisture use by crops depending on the fertilizer systems for the creation of 1 C of grain units (g.u.) and from sub-arable layers are determined. In comparison with the liming background, the use of organic fertilizers reduced the water consumption coefficient from 9.6 to 8.5 mm/C g.u., their combination with a single dose of NPK - up to 7.3, and with a double dose - up to 6.8 mm / C g.u. Based on the amount of moisture used by crops, their possible yields are calculated. In spring crops, the amount of precipitation consumed (326-356 mm) corresponds to the use of 2.7-3% of the FAR and provides 54-60 C/ha of grain, in winter rye and wheat - about 4% of the FAR (yield 71-80 C/ha). In perennial grasses for 2 mowing, the moisture consumed is enough to use about 3% of the FAR., in potatoes -1.5%.

Introduction. Nowadays, in front of large cities, there is an acute problem for finding ways of environmentally safely dispose of accumulated sewage sludge and the possibility of its use. The most profitable way to utilize sewage sludge is to use them as organic fertilizers in agricultural production due to the high content of biogenic elements (nitrogen, phosphorus, potassium) and organic substances in their composition. However, the presence of heavy metals, pathogens, and other toxicants necessitates the study at the regional level the possibility of using these sediments as fertilizers. In each specific case, it is necessary to apply a scientific approach to the use of sewage sludge, since their composition is characterized by a qualitative and quantitative variation of chemical compounds. The purpose of the study was a hygienic justification for the possibility of using sludge for wastewater treatment from the municipal facilities in agricultural production as an organic fertilizer. Material and methods. The object of the study was sludge after treatment with flocculants and centrifugation and sludge stored on the sites of Lviv municipal facilities for 1, 6 and 18 months. In the experiment, the distribution of sludge components in the “plant-soil” dynamic system, as well as the degree of their accumulation in test plants, was determined. Quantitative determination of the of chemical elements content in samples of sludge and phytomass was carried out by atomic absorption spectrophotometry. Results. The effectiveness of the use of sludge from the municipal facilities for wastewater treatment in agricultural production as an organic fertilizer has been studied. It was found that the sludge dose of 50 tons/ha, using immediately after centrifuge, can not be used in the fields as a fertilizer. This dose caused a high phytotoxic effect on plants. The dose of used sludge (30 tons/ha after 1.5 years of maturing on silty areas) had a less pronounced phytotoxic effect, but the fact of fluorine, lead, cadmium, arsenic, mercury and manganese translocation from soil into the plants in high quantities was observed. This dose also cannot be used in the fields as a fertilizer. The use of a smaller dose should be justified by additional experiments.

The implementation of potato potential yield (30-40 tons per hectare) in the forest-steppe zone of the Middle Volga is possible with the introduction of highly adapted varieties, the use of evidence-based farming cultivation. The authors studied the efficiency of promising new varieties of potatoes on gray forest soils in the Republic of Tatarstan. It was founded that when treating by calculated dozes of fertilizer potatoes of Rozhdestvenskiy, Impala, Sprint, Feloks, Red Skarlet varieties on gray forest soils of the Middle Volga steppe on average for three years the planned harvest tubers 40 or more tons per hectare was formed. The yield of Aroza, Nevskiy, Adretta varieties was 36,51-37,30 tons per hectare. In the more favorable moisture 2009 year, the high yields of tubers were formed by varieties: early-maturing Impala (58.35 tons per hectare), Red Skarlet (57.02 tons per hectare), Feloks (55.83 tons per hectare), middle-maturing Adretta (57,22 tons per hectare), Rozhdestvenskiy (56.13 tons per hectare). In drought 2010 year, in the application of irrigation higher yields of tubers formed early-maturing varieties: Sprint (21.52 tons per hectare), Red Skarlet (21.06 tons per hectare), Impala (20.59 tons per hectare) and Aroza (20.53 tons per hectare) and middle-maturing variety Nevskiy (21.74 tons per hectare). Less yields in 2010 were such varieties as Adretta - middle-maturing (14.58 tons per hectare) early-maturing Rokko (13.67 tons per hectare). The difference in yield of these varieties in this year reached 7.16 tons per hectare, the higher yield more than 20 tons per hectare was provided by 5 species of 9 studied (20,53-21,74 tons per hectare).

The efficacy of using the calculated doses of fertilizers for upcoming harvests potatoes was studied. As a result of studies of the potato leaf area formation dynamics on gray forest soils of the Middle Volga steppe, its dependence on mineral nutrition level was revealed. Their impact on productivity and quality of potato tubers was identified. The efficacy of calculated doses of fertilizers for upcoming potato harvests were studied. Fertilizing crops by scheduled doses, counted by cash- balance method for upcoming yields of 25-40 tons per hectare, provided the formation of 90,5-98,0% of the target yield. The nitrate content in all versions of the experiment was below the maximum admissible concentration. However, with increasing fertilizers amount, their content was increased in 1,24-1,73 times (without fertilizers - 41 mg / kg of wet weight). As a result of studies of the dynamics of potato leaf area formation on gray forest soils of the Middle Volga steppe, we revealed its dependence on mineral nutrition level. The photosynthetic potential (PP) during the growing season of potato Udacha, was in the first version without fertilizers 2.173, the second 2.520, in the third 2.910, fourth 3.196 and fifth 3.575 million square meter per hectare * days, i.e. with an increase in fertilization rates, the photosynthetic potential increased accordingly to 0.347-1.402 million units, for every thousand units of photosynthetic potential we obtained from 7.2 to 10.8 kg potato tubers. A starch content varied from a few of fertilizers. The maximum starch content (14 %) was obtained in the second way, calculated on the tuber yield of 25 tons per hectare. A further increase in the background was led to some of its decline.

This paper is the first of a series of works devoted to the general issues of organic fertilizer spreading machines. Although the working process of solid organic fertilizer machines does not contain a large number of random constituents, however, the basic component, the material administered, gives the random characteristic of the process. In addition, another random component that influences the working process of the machine is the interaction of the work organ that performs the tearing and distribution of the scattered material with this material, as well as the movement of the fragments of material onto the surface of the device. A third random component is the movement of the material scattered into the atmosphere. The fragments of scattered material exhibit shape irregularities due to fragments during dislocation from the mass of feed material and due to particle collisions while moving into air until the contact with the soil. Therefore, the phenomenon of spraying the organic fertilizer on the layer from the soil surface is, as a whole, a random process. Consequently, it is logical to have experimental research prioritized in the study of the work on the distribution of solid organic fertilizers. The role of this article is to present the experimental results, some conclusions and to prefigure several theoretical or theoretical-empirical research directions. The results contained in this article are basics in all the other essays related to the topic machine.

Information dissemination through agricultural extension workers can increase knowledge, can change behavior, and attitudes of farmers, especially regarding the use of organic fertilizers. Changes in behavior and attitudes can be seen from the participation of farmers in using organic fertilizers. Participation through the participation of farmers can be a more efficient way to achieve the stated goals. The aim of this study was to examine the role of agricultural extension agents in the use of organic fertilizers in the Province of South Kalimantan. Measurement of the role of agricultural extension agents in the use of organic fertilizer using the median score. The role of agricultural extension agents in the use of organic fertilizers includes: the role of agricultural extension agents as motivators, mediators and supervisors. The role of agricultural extension agents as motivators in the use of organic fertilizers gets a median score of 4, which means that agricultural instructors are eager to encourage farmers to use organic fertilizers due to a fairly good farmer response so that extension workers can motivate farmers to use organic fertilizer. The role of agricultural extension agents as mediators in the use of organic fertilizers gets a median score of 4, meaning that the tasks of agricultural extension agents as mediators have been carried out well. Information or policies from related government or extension agencies are delivered by extension agents to farmers, both through regular meetings and incidental meetings. While the role of agricultural extension agents as supervisors in the use of organic fertilizers has a median score of 5 which means that the role of agricultural extension agents has been carried out to the maximum seen from the frequency of implementation of guidance by extension agents.

The analysis of ascariasis prevalence in the Chuvash Republic for the period 1997-2017 was carried out depending on natural and anthropogenic environmental factors. As a result of multiple regression analysis including 61 factors integrated into the matrix for regression analysis, 19 factors were selected which were statistically significantly associated with the incidence of ascariasis depending on the administrative-territorial structure of the Republic. The chosen factors are divided into six groups: group 1 – factors reflecting the characteristics of water balance and the distribution of water masses in the area: (a) average annual flow (coefficient = 0.761), determining the amount of water flowing along river beds per year; b) the number of drilled wells (coefficient = 0.5133); c) the average snow cover height (coefficient = 0.2940); d) 4) the average amount of precipitation for the winter period (coefficient = 0.0073); e) the average number of sources whoch do not conform to sanitary standards and regulations (coefficient = -0.3309); f) drainage network density in km per km2 (coefficient = –0.0152), i.e. water balance and distribution of water masses in the territory of the region determine the direct impact on the incidence of ascariasis; group 2 – factors created by agricultural human activities related to soil: (a) the average annual number of poultry per 100 hectares of crops (coefficient = 0.2265); b) the specific weight of agricultural livestock areas in the entire area of agricultural land,% (coefficient = 0.2537); c) sheep stock per 100 hectares of agricultural land (coefficient = 0.1838), as it is known, livestock objects maintain viable helminth eggs for a long time; group 3 – ecological-climatic factors: a) fluctuations within the limits of baseline radiation background (coefficient = -0.2537); b) average year-round temperature (coefficient = –0,1103); c) depth of soil freezing (coefficient = –0.0412) – this group of factors is a deterrent in the spread of ascariasis because it directly affects to slow down the maturation of eggs and contributes to the early loss of vitality. As a result of cartography, a high incidence of ascariasis is noted in areas with prevalence of typical gray forest soils in combination with light gray and dark gray forest soils, in areas with gray cespitose- cryptopodzol soils. It is Krasnochetaisky region – 171,17±108,36 cases per 100 thousand population, Alikovsky region – 118,5±74.4 and Shumerlinsky region – 70,5±47,8. The minimum morbidity is in Yalchiksky region – 12,10±9,14. Conclusions: 1) the incidence of ascariasis in the territory of the Chuvash Republic is of a mosaic character. The incidence of ascariasis prevails in administrative-territorial regions located in the western part of the Chuvash Republic; 2) it is statistically proved that such a hydro-geological feature of the territory as annual runoff, including spring flooding, has a significant negative impact on morbidity; 3) such environmental and climatic factors as annual average temperature and the depth of soil freezing, have a deterrent effect on the incidence of ascariasis.
