A mathematical model for evaluating the diagnostic value of signs in soil quality control tasks

Abstract

The article deals with the solution of the problem the integrated management of land quality control agricultural use in order to fulfill the norms of the natural usage and solving the predicted maximum yield and strategic management of technological processes in order to reduce dehumification. The strategic direction the use of land resources in future determines the nature of its further use, the choice of crop rotation, the use of optimal technological processes, sowing time and harvest, etc. An essential element for this is the quality control of field work, physical, chemical and biological indicators of human impact. A mathematical model for the diagnosis of an object of verification capabilities to give further generalizing the soil quality indicators. Is considered diagnostic value of signs (indicators of chemical and physical condition of the land, the quality of treatment results of the evaluation, chemical reclamation, quality of work fertilization, conducted by seeding, herbicide application, inspection of quality measures for pest control, harvesting, and so on.). Analytical dependence criteria with the possibility of diagnosing the object and obtain further general indicators of quality control are developed. Experimental data obtained in accordance with the regulatory requirements within a specified time. Spend diagnosis using probabilistic pattern recognition methods. Obtained decision rule by which, the totality of symptoms diagnosed, classified as one of the possible states (diagnoses). It estimates the probability of the decision and the risk of erroneous decisions. Quantitative determination of the diagnostic value of a single attribute, the complex features or features generalizing conducted on the basis of information theory. The diagnostic value of signs is determined by the proportion of the amount of information that has brought this feature, the status detection system. The results of research can be used to formalize the assessment of ground conditions with the aim of organizing land management and cadastre, address common diagnostic problems of strategic and current correction and improvement of the quality of land, to produce an effective and optimal solutions to increase yield.
