ACCELERATED REPROCESSING TECHNOLOGY FOR RECYCLING PIG MANURE INTO ORGANIC FERTILIZER
06.00.00 Agricultural sciences
DescriptionThe 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

DescriptionThe article examines the creation of the expert system in the development of epiphytotics in winter bread wheat sowing. Increasing the accuracy of the forecast epiphytotics should be based on the improvement forecasting of move daily temperature (minimum, maximum and average). In this case, the calculation algorithm must not be cumbersome. In the algorithm, there are indicators of cyclical annual variations of temperature, i.e. the change in average daily temperatures for the year. For the treatment method of local forecast of daily average temperatures during the year used data of meteorological station for 9 years. Having considered the main issues to epidemics of brown rust and its influence on the production of wheat cenoses, you can proceed to the modeling expert logic. The analysis includes the following indicators: cultivated variety; agricultural machinery (predecessor, fertilizer, pre-processing, and others.); general condition of sowing; phase of plant development at the time of the field survey; date of onset of the disease (if selected); prevalence of sowing at the time of observation. Installed that the purposeful creation of varieties of winter wheat resistant to the pathogen, it is necessary to carry out environmental testing stability as a latent breeding and recommended sources and sustainability of donors, which will allow to plan economic occupancy resistant genotypes of winter wheat

DescriptionThe experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%.

DescriptionAn experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance

DescriptionThe article presents the data of 40-year-old variety-trial cultivation of hybrid black poplar and balsamic sections, as a result of which addressed issues of selection range of appropriate varieties, their cultivation technology, aspects of agrotechnology and protection against pests. At the same time, it absorbed and non-forest land reclamation funds, in particular sandy and shell, lowhumus, floodplain soils. As a result, the five-year variety trials found that under the conditions of the Eastern Azov on humus shell rock underlain by low-mineralized groundwater on accessible depth for roots (up to 150 cm), the most highly productive and are stable clones of Euro-American poplar: Brabantika-175, Sanrau-59, a Moshnyi-236 and 195 , Bahel, ZS-33 Vernirubens, 60001/1, Caroline-162. In terms of growth, they are superior to the local Canadian poplar and other varieties of poplars. Resistance to environmental and biological factors of the environment most highly productive species and varieties of poplars are much higher than the low productivity. Culture of poplar planting might create unrooted plants directly on the silvicultural area, which reduces the cost of rooting plants at the nursery, their digging and transportation and provides a high survival rate. Culture of poplar are used for the afforestation of poor sandy forest-steppe zone arrays, often introduced as the main breed at shelterbelt afforestation
