Different tillage methods have varying effects on crop residue distribution in the cultivated layer. This leads to uneven development of soil microorganisms in the 0-10, 10-20, and 20-30 cm soil layers. Azotobacter developed better with moldboard plowing to a depth of 20-22 cm, while cellulolytic microorganisms showed greater activity when crop residues were incorporated to a depth of 28-30 cm.
