agricultural engineering. SUBSTANCE: share for subsurface broadcasting of seeds and fertilizer has hoe, hollow tine-material guide, and seed distributor made in the form of truncated cone with larger upper base having diameter equal to that of tine-material guide. Pneumatic material guide is tangentially connected to tine-material guide. Air discharge branch pipe is extending along axis of tine-material guide. Lower cut of air discharge branch pipe is positioned below pneumatic material guide and tine-material guide junction zone. Share of such construction provides uniform distribution of material over the whole area of subsurface layer. EFFECT: increased efficiency and simplified construction. 2 cl, 2 dwg
