Linear and nonlinear models in soil quality evaluation
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 102, Issue
Abstract
The article presents the results of research on the development of pedotransfer models of the linear and nonlinear (quadratic) type constructed on the basis of samples from the database "Ukrainian Soil Properties". With the help of these models a dependence of soil quality expressed in soil rating points on the basic properties of soils was obtained. The role of agrophysical and agrochemical properties of soil in the change of soil rating was traced, their statistical estimation was made. Pedotransfer models of crop yield dependence on soil properties have been constructed, their processing allowed determining correction factors considering soil fertility decline under the effects of negative factors.
