METHOD OF INTRASOIL TREATMENT, TILLAGE, AERATION, IRRIGATION, FERTILIZATION OF ROOT LAYERS OF SOIL Russian patent published in 2024 - IPC A01B79/02 A01C21/00 

FIELD: agriculture.

SUBSTANCE: method includes treatment, aeration, irrigation, fertilization of root layers of soil, which are carried out by compressed air pulses inside soil by means of pneumatic hydrodrills, vertically immersed into soil to a depth corresponding to thickness of root layer, characteristics of soil and type of plants, propulsor, made in the form of a closed continuous elastic band, due to the pneumatic cylinders working force and the vibration effect, overcome the penetration force of the root layers of the soil and simultaneously convert the deformation of the elastic element of the tensometric force sensor of the penetrometer into an electrical signal, value of which is directly proportional to the value of soil penetration force. Depending on value of electric signal by air electropneumatic valve, frequency and value of pressure of compressed air pulses are set. After supply of compressed air pulses to soil, tillage and aeration, solutions of hydrogel and fertilizers are supplied to formed soil pores, cavities and micro cavities under pressure set by electropneumatic valve for liquid depending on value of electric signal of penetrometer. Pressure of compressed air and solutions is stabilized, plants are irrigated and root system fertilized directly. Belt covers the soil surface, prevents damage to the root system of plants, loss of compressed air and solutions; in the course of movement of the belt, pneumatic hydraulic drills are removed from the soil.

EFFECT: method increases quality and efficiency of treatment, aeration, irrigation and additional fertilization of root layers of soil, reducing power consumption with maximum preservation of biological and environmental parameters of soil, providing high mobility and energy efficiency of treatment of the root system of plants.
