This invention provides for a single replaceable point to be used in the furrowing of the soil and the simultaneous creation of separate and distinct seed and fertilizer beds. This point attaches to a main body plate that, in turn, attaches to the seeding unit. In this way a minimum amount of effort is required to replace worn or broken points. The integrated side banding seeding assembly attaches to the soil contact end of hoe drills, air drills or air seeders for agricultural use. It allows for the separate placement of seed and fertilizer in one farm operation. Two separate knife-like edges on the soil contact surface act in a cutting fashion to create two openings in the ground. The seed is placed first. The fertilizer placement is offset below and to the side of the seed placement. The layer of earth between the two products creates maximum separation. This device may incorporate an air vent apparatus to reduce the air pressure applied to the products being distributed and reduce the speed of the products as they strike the ground. Placement of fertilizer below and to the left or below and to the right of the seed is achieved through opposite, or mirror image, points. |
