METHOD OF DETERMINING TIME OF REGULAR VEGETATION IRRIGATIONS Russian patent published in 2015 - IPC A01G25/00 G01N33/24 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of land reclamation, particularly to irrigated agriculture. In the method the timing of the regular vegetation irrigation under conditions of the Northern Caucasus is determined using the sensor. On the irrigated field in the soil, to half the depth of the active layer of the soil, the probe-sensor is inserted, made in the form of a bayonet with transverse grooves at its end and a scale of depth of immersion with 5 cm graduations from 0 to 50 cm. Upon reaching the middle of the active layer for each individual plant species the probe-sensor is removed from the soil and at its end with the grooves the degree of humidity of the soil and the time of regular vegetation irrigation is visually determined, which is settled if on the end with the grooves of the probe-sensor there are no traces of moisture and clumps of wet soil, which corresponds to average moisture content of the active layer of soil 75-85% of field capacity (FC). At that the place for inserting the probe-sensor should be in the middle of a row of plants, in the wetting contour zone located in the middle of the section, it should not be compacted from the surface by agricultural machines, devices and people.

EFFECT: method enables to simplify the timing of regular vegetation irrigation and provide plants with soil moisture.
