Abstract: Prior to sowing seeds of agricultural crops, awareness of the thermal, water, and light regimes of the land is of great importance. In this article, we studied the thermal and temperature conditions of flat and inclined lands through the heat transfer equations in the soil. At the same time, the temperature invariance at a certain depth from the soil surface was mainly obtained, on the basis of which a formula for calculating the soil temperature from the sediment was derived by the method of harmonic analysis. In addition, formulas for flat Land and temperature regimes of 10˚, 20˚, 30˚ slopes relative to the horizon for southern and northern surfaces have been released. Theoretical calculations have shown that the temperature on the slopes is higher than on the flat lands compared to the experimental results. This suggests that agricultural workers are creating conditions for sowing plant seeds in the ground in early spring.
