METHOD OF INTRODUCING BIOPREPARATION INTO UPPER SOIL LAYER Russian patent published in 2020 - IPC A01G25/06 A01C23/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Method consists in pulsed discreet subsurface irrigation using syringe element (1) under pressure. Injection starts from the moment the syringe element submerged into soil (2), and the injection is completed at the moment of its extraction from the soil. Watering is performed successively first with a biopreparation solution and then with water. Biopreparation solution is introduced at depth of 0.02–0.05 m with pitch 0.20–0.25 m so that diameter of cylinder treated with biopreparation solution of soil and lower surface of plant residue located on soil is 0.10–0.15 m. Water is introduced 3–5 days after application of biopreparation solution 3–4 times with period of 3–7 days to depth of 0.05–0.10 m so that cylinder diameter of soil moistened with water makes 0.07–0.11 m.

EFFECT: improved conditions for development of biological objects contained in the biopreparation.
