Temperature regime of agrosoddy-podzolic soils on slopes of different steepness

Soil temperature regime at the depth of 20 cm may vary considerably on different parts of a given slope. This variation may be related to the position of the particular site on the slope and to the geomorphic features of the slope, including its surface inclination. The soils of the upper steep part of the slope of southern aspect are subjected to more active warming in the spring. They are characterized by higher cumulative temperatures above 10°C. The degree of this difference depends on the particular weather conditions. The differences in the soil temperature regimes may be the reason for the unequal crop yields on the different parts of the slope.
