FIELD: agriculture.
SUBSTANCE: on the upper surface of the soil sample a weight is placed. The water flow is passed through the sample. Alkyldimethylbenzylammonium chloride concentration in the flow of water is registered, which passes through the sample of the soil. The beginning of the weight immersion is registered, the parameters of the sample and the water flow are measured, the filtration coefficient of soil is calculated from the measured indicators. In the water flow passed through the soil sample the value of alkyldimethylbenzylammonium chloride concentration is registered, and in reducing the concentration value greater than 6% of the initial value, to the water flow, directed into the soil sample, the solution of alkyldimethylbenzylammonium chloride is added, restoring the value of alkyldimethylbenzylammonium chloride concentration in the water flow, which has passed through the soil sample, to the initial value.
EFFECT: increase in reliability of determining.
