THE SPATIAL VARIATION OF HUMUS CONTENT IN THE SOILS WITH DIFFERENT ANTHROPOGENIC LOAD

An assessment was made of the spatial variation of humus content in soils of lands of different agricultural use. The objects were the soils of the cultivated field and fallow land for more than 15 years. It was established that the humus content in the soils on the arable land was 1.4-3.5% (V = 15.5-33.9%), fallow land - 1.6-3.3% (V = 17.0-34.8%). Taking a field out of production for 15 years does not lead to mathematically proven changes in the humus content in soils.
