چکیده
Abstract Liquid mineral fertilizers (LMF) have a high sorption ability, can be metered precisely, and the intra-soil application of LMF is relevant. However, agricultural equipment for this process that introduces liquid fertilizer under processed soil layer in form wide band has not yet been proposed. The purpose study to evaluate performance 102 mm rectangular discharge microchannel proposed tillage knife designed deep influence length ( L ) slot height h on uniformity discharge. Solidworks Flow Simulation ® was used during investigations, simulation results were compared with experiment results. It determined effective water at V i = 3–4 m·s −1 0.1 (±0.01) mm, an 20 (±2) depends . Sheet thickness will change distance 10–15 b ). Fall angle 0–5°. In conclusion, asymmetrical feed applicable LMF, surface tension effect considered. A way enhancing sheet geometrical modification channel shape.
