Our research has shown that abiotic factors have a significant impact on the distribution of the earthworm Aporrectodea caliginosa
trapezoides, which is distributed in the agrocenoses of the Sangzor Valley. We found that Aporrectodea caliginosa trapezoides is
distributed in the agrocenoses near the city of Jizzakh. Its average body length is 60-166 mm, its thickness is 4-8 mm, the number
of rings is from 109 to 230, its skin is brown, sometimes colorless. The cross-section of its body is round or slightly flattened. The
belt consists of 26-36 rings. As a result of the influence of abiotic factors in the soil, earthworms were observed to migrate from
one layer to another.
