FIELD: measurement equipment.
SUBSTANCE: method to determine coefficient of filtration of soil, by which water flow is sent via a soil sample. A sinker is placed on the surface of the soil sample, the start of sinker submersion is recorded. Then parameters of the sample and the water flow are measured. Then the soil filtration coefficient is calculated using the measured indices. At the same time they additionally record the value of humic acid concentration in a flow of water that has passed via the soil sample, and as the value of concentration reduces by more than 10% of the initial value, solution of humic acid is introduced into a flow of water sent into the soil sample, thus restoring the value of concentration of humic acid in a water flow that has passed via the soil sample, to the initial value.
EFFECT: expansion of functional capabilities of filtration coefficient determination in soil exposed to humic acid, in black soil area.
