Use of diagnostic value of signs of soil quality at its ecological control

Abstract

This study addresses the possibility of solving the problem of integrated land quality management in the organization of its control in order to meet environmental standards and predictive tasks of obtaining maximum yield, strategic management of technological processes to reduce dehumidification, organization of land cadastre and ordering the land in terms of agricultural management.

The strategic direction of land resources use in the future determines its further nature of use, selection of crop rotations, application of optimal technological processes, terms of seeding and harvesting, etc. ...

The necessary link for this is the quality control of field work, physical, chemical and biological indicators of anthropogenic impact.

A mathematical model is proposed for the possibility of diagnosing a control object and further generalizing its quality (soil). Diagnostic value of features (indicators of chemical and physical state of the earth, results of estimation of quality of cultivation, chemical reclamation, quality of works on fertilization, sowing, application of herbicides, carrying out quality control of measures of pest control, harvesting works, etc.), development of analytical dependencies of criteria, is considered the ability to diagnose the object and obtain further generalizations of the quality of control. The experimental data are obtained according to the regulatory requirements within the specified time limits.

The diagnosis at the probabilistic methods of recognition is as follows. A decisive rule is constructed by which the set of diagnosed features is assigned to one of the possible conditions (diagnoses). The likelihood of a decision being made and the degree of risk of a wrong decision are estimated. The quantitative determination of the diagnostic value of an individual trait, complex of traits or generalizations is based on information theory

The diagnostic value of a trait is determined by the fraction of the amount of information that the trait brings to the status recognition system. Most features (difficult) in assessing the condition of soils determine the presence of a number of gradations - diagnostic intervals, as it is always possible to quantify clearly how thresholds are.

The results of the study can be used to formalize the assessment of soil conditions in order to streamline land and cadastre, solve common diagnostic problems of strategic and ongoing adjustment and improve the quality of land to obtain effective and optimal solutions for improving yields.
