Theoretical foundations of calculating the system for the organic fertilizers introduction in suction pipelines of pumping stations for fertilizing irrigation agricultural crops

Purpose: to substantiate theoretically the calculation of system for introducing organic fertilizers into suction pipelines pumping stations during fertilizing irrigation agricultural crops. Materials and methods. The foundations calculating are developed on basis literary sources authors’ research. If there is a composition nutrients in manure cattle (CM), horse, pig or sheep planned harvest adopted crop, one-time annual application amounts most toxic element – nitrogen calculated. It indicated that case deficiency phosphorus potassium, an additional mineral introduction carried out. Results. An example amount mixture corn silage when removing with accepted green mass 500 q/ha provided. determined by: rate, cubic meters/ha; content kg/ha; volume mixture, 0.15 %. In example, performed possible presence drains according two variants technological schemes: without using mixer, from storage tank directly pipeline; pipe mixer. For calculation, initial data hydraulic parameters given, consumption humidity 92–95 % taken as main parameter. Conclusions: theoretical allows determining rate fertilizer input jet
