METHOD TO REGISTER WATER EROSION OF SOIL Russian patent published in 2012 - IPC G01N33/24 

FIELD: measurement equipment.

SUBSTANCE: invention refers to agriculture, with regard to assessment of efficiency of anti-erosion actions. The method includes measurement of drain volume with portions with the help of a jack pump, water sampling with a slot water separator with a water separation ratio K₁, measurement and analysis of samples for content of solid residue, besides, the drain from the water separator is directed into an accumulation reservoir during the entire drain period, and upon its completion, the accumulated volume is stirred up and repeatedly sent via the jack pump and the water separator with a water separation coefficient K₂, besides, the coefficient K₂ is established to produce one final sample from the accumulated volume for analysis in the form of a weight average sample with reduction of drain volume, and the analysis result - weight of solid residue - is divided into the product of K₁ and K₂ coefficients, and the total weight of the washed soil is produced.

EFFECT: invention provides for achievement of registration accuracy and simplification of soil loss.
