COGNITIVE TECHNOLOGIES FOR SIMULATING OF A SYSTEM OF IRRIGATED FARMING OF REGION
DescriptionIt is suggested to realize simulating of a system of irrigated farming by means of cognitive technologies. A cognitive map for interaction of irrigated farming system with the environment is developed. Re¬search principles for scenarios of system behavior of a simu-lation model are stated

Description
The article contains a scientifically based approach to assessing and improving the reliability of DMU "Frigate" in the conditions of the Rostov region. The studied parameters for the elements with the lowest resource were: mean time between failure, mean time to repair, probability of failure, the parameter flow of failures, failure rate, actual and allowable factors of readiness. The analysis of the main faults of DMU "Frigate", identified nodes and elements, characterized by the low reliability, for which the dependences of probabilities of failure-free operation, as well as the dependence and developed the procedure for calculating the optimal duration of recovery of failed elements, to ensure acceptable availability. Statistics on major faults refuse items were collected over the three irrigation seasons from 2013 to 2015, were investigated failures due to wear of the elements for 17 irrigation machines. As a result of the research we developed mathematical apparatus of calculation and the comparative assessment of the readiness of the parks sprinklers of various farms to perform their processing functions at the same and different number of machines. We obtained the dependence for determining the allowable duration of the recovery elements that will allow you to determine the main directions of improving the reliability of DMU "Frigate" during the operational phase

LINEAR CONTOUR PARAMETERS HUMIDIFIED AT DRIP IRRIGATION
DescriptionThe article considers technique of field and laboratory studies contours humidification under drip irrigation, from which they were derived depending determining of geometric parameters of these contours. Such as depth contour humidification and radius. Describes the comparison of calculated results with experimental mathematical equations and laboratory data. Materials recommended articles used in the design drip irrigation fruit and grapes gardens, vegetable gardens

06.00.00 Agricultural sciences
DescriptionThe purpose of the research is to assess the ability of reclamation plantations of walnut and black nut on the accumulation of heavy metals in their phytomass – leaves, shoots, and fruit. The studies were conducted in the Rostov region, the Krasnodar and the Stavropol regions. In the samples of vegetative aboveground and soil (under the canopy nuts) we have defined qualitative content of total forms of heavy metals of Cu, Ni, Co, Zn, Mn, Pb, Cd, Cr. This ability is the accumulation of heavy metals in leaves, shoots and fruit that fall from the atmosphere. Later, the bulk forms of these metals with the annual litter come to litter, and then – into the soil
