New approaches to the assessment of genetic potential of fertility of authomorfic sod-podzol natural soils taking into consideration the energy humus supply are shown in the conditions of the Republic of Belarus. New methods of evaluation of different extent cultivated soils of various genesis such as sandy, loamy sandy and light loamy of granulometric composition, and also hortic anthrosols are examined. Internal energy of humus in a 0-50 cm layer of natural sod-podzol soils of different genesis and granulometric composition is calculated. Differences between internal energy of humus in 0-50 cm layer of natural sod-podzol soils and continuous-cultivated soils are shown. It is shown that the amount of internal energy of humus in the 0–50 cm layer of natural authomorfic sod-podzol soils can be used for the assessment of their natural fertility, in agronatural analogues this index can be used for the effective assessment of fertility, and in hortic anthrosols - for the assessment of the rate of potential fertility of soils.
