AGRICULTURAL IMPLEMENT

摘要

"AGRICULTURAL IMPLEMENT" An implement (10) and method of its operation used to modify soil drainage and acidity. The implement (10) includes rotating disk slot cutters (40) which are drawn through the soil so as to cut a slot in the soil without substantially disturbing the surrounding soil. Gypsum and/or lime is supplied at a controlled rate into the slot formed in the soil before the soil removed in forming the slot is returned by shrouds (52) partly enclosing the disks (40). The controlled supply of the gypsum and/or lime is affected by a plurality of augers (90) held within the base of a hopper (14) filled with gypsum and/or lime. The augers include auger flights (93) immediately above hopper outlets (87) and a plurality of spaced radially extending pegs (97) along the remaining length of the augers (90).
