The results of studies on the development of a population of rain compost worms in a substrate of crushed lawn grass and remnants of herbs are presented. This problem is of scientific interest and is of great practical importance in connection with the disposal of urban organic waste in the conditions of the region. One of the objectives is the recycling of urban organic waste, which have several important aspects. Urban organic contains some mineral elements in hard-to-reach (low soluble) form. Vermicomposting greatly facilitates the process of extracting these substances and their absorption by plants. The aim of the work is to study the characteristic features of the development of the compost worms population in the substrate of the remains of herbs when vermicomposting under the conditions of the Tyumen region. The findings of studies studying the characteristic features of the development of a population of earthworm compost worms in a substrate of lawn grass and grasses remind that the peak of worms' reproductive activity begins after two weeks of adaptation to a new substrate and the second cocoon number increases after the fifteenth week of development, and the juvenile stages hatch begins after the fourth week of development and a sharp rise in numbers after the seventeenth week. The rise in the number of adults begins after eleven weeks of cocoon development and juvenile stages. After five weeks of development, adults began to lay cocoons. This is marked by a sharp increase in the number of cocoons, and then the juvenile stages.
