Information and energy assessment of the creation of soils with specified properties

The paper considers the information and energy assessment of soil fertility. It is shown that soil cultivation is accompanied by an increase in soil humus content, absorption capacity, content of biophilic elements, accumulation of energy in the soil, optimization of information relationships in the soil. Thus, the energy content in poorly and well cultivated sod-podzolic soils was 351.7 and 510.7 million kcal/ha, respectively. When cultivating soils, the content of mobile forms of biophilic elements in them increased, the relationship between soil properties and crop yield became more stable. It is shown that on more cultivated soils it is more profitable to grow crops that are more demanding of fertility, accumulating more energy on these soils than crops that are less demanding of fertility. The change of optimal soil properties for individual crops depending on the level of intensification of production is shown.
