PROBABILISTIC MODEL OF THE PROCESS OF REDUCTION OF THE PRICE FOR PLANNED ACTIONS

abstract 1321708026 issue 132 pp. 324 – 334 31.10.2017 ru 383
The soil fertility increase issues are very relevant now. Intensive development of agriculture cannot be made effectively without complex actions for farmlands protection from different types of degradations. On the one hand, it is necessary to ensure the maximum harvest of crops, and to preserve and increase the fertility of the soil and prevent negative anthropogenic impact on the environment on the other. For an extended reproduction of soil fertility, a system of measures is necessary for introduction of mineral and organic fertilizers into the soil, agrotechnical and reclamation methods, stimulation of humus formation processes, and so on. Therefore, methods are important that allow us to estimate the planned measures in advance to improve soil fertility and to eliminate environmental damage. In the article, the estimated parameters are treated by random variables. This allows us to consider the uncertainty in terms of probability distributions. It is offered a probabilistic model of the process of reducing the price of the proposed activity. Mathematical expectation, variance, distribution density of the considered random variable probabilities as the main characteristics of the object state price are calculated. The model can be used to address issues of rational use of land, scientifically based land management organization, when drafting land reclamation project

PROBABILITY OF ESTIMATION OF AMELIORATIVE CONDITION OF IRRIGATED FIELD WHEN USING BIOTECHNOLOGY

abstract 1211607110 issue 121 pp. 1778 – 1786 30.09.2016 ru 381
The biotechnology (year - round utilization of livestock and spirit wastages) was developed for the protection of farmlands and water objects. Technology of processing of organic wastages by means of earthworms (vermicomposting) gives the chance to use wastages of livestock complexes, to make a sewage disposal at minimum energy consumption. In the field experiment which was made in the training farm called "Kuban" for the detailed studying of influence of the held events there were put the platforms. The technique of probability of estimation of ameliorative condition of an irrigated field is given in the article. The nonparametric statistical assessment of degree of soil compliance to the normative conditions is defined

THE MATHEMATICAL MODEL OF ECOLOGICAL SITUATION ON THE RICE IRRIGATION SYSTEM

abstract 0440810003 issue 44 pp. 48 – 64 25.12.2008 ru 3196
Solving of problems of the influence of irrigation on ecological situation and creation of optimum land-reclamation conditions are impassible without using of the mathematical modeling methods. The work provides the idea of solving of the land-reclamations problems with the using of systematic-cognitive analysis.
