Abstract
The farm attached to the Zafarabad district of the Jizzakh region of the Republic of Uzbekistan is the most important part that ensures the fertility of the humus soil with 1270 samples of 6350 hectares of land. It contains the main plant nutrients (carbon, nitrogen, phosphorus, etc.). Simple compounds are formed from plant decay. It absorbs calcium, magnesium and other chemical elements and keeps them in the soil, binds the mineral part of the soil with each other and creates granularity. As a result, a strong, water-resistant composition of the soil is formed. Accumulation of humus is a process determined by the amount of organic residues (roots) falling into the soil every year, their biological and chemical changes, and the nature of the soil microflora (fungal, bacterial, anaerobic or aerobic).
