FIELD: agriculture. SUBSTANCE: investigated area is profiled electrically by a non-contact method and remotely sounded. The degree of salinization is found by correlation of measured electric resistance at a given point and the data of sample analyses at reference points. Ground water level is determined by divergence of electrical resistance values registered at one point along the course and perpendicularly to the course of ground structures. EFFECT: higher efficiency. 3 dwg
