METHOD OF APPLYING CHEMICALS MIXED WITH IRRIGATION WATER Russian patent published in 2001 - IPC

FIELD: agriculture. SUBSTANCE: method involves preparing required volume of chemical solution and introducing it into portion of irrigation water while it is accumulating in vessel. Mentioned operations are performed in succession and independently one of the other. Designed dose of chemicals is added into irrigation water in accordance with number of cycles, concentration and volume of dosed solution at dependence of K=K1 [0.01(100-V)] ⁿ, where K is concentration of mother liquor after dosing cycle (cycles), when its volume reaches basic value, %; K1 is basic concentration of mother liquor, %; V is volume of dosed solution for one cycle at the rate of 100 ml, ml; n is number of dosing or irrigation cycles. Method is used for multi-purpose employment of discrete irrigation systems for applying mineral fertilizers and soil pesticides. EFFECT: increased efficiency and uniform distribution of chemicals over field. 1 tbl, 1 ex
