Abstract

A seeding apparatus includes a trailing arm pivotally attached to an implement frame and a bias element exerting a downward bias force on the trailing arm. Fertilizer and seed furrow openers are attached to the trailing arm such that a seed furrow has a seed furrow depth less than a fertilizer furrow depth of a fertilizer furrow. A packer wheel is rotatably attached to a rear end of the trailing arm. A furrow controller is selectively operative to change the relative positions of the seed furrow opener, the fertilizer furrow opener, and the packer wheel to attain a desired one of a plurality of configurations where in each configuration the seed furrow has a seed furrow depth less than the fertilizer furrow depth to provide a separation distance. The seed depth and separation distance is quickly and conveniently increased in adverse soil conditions and decreased in favorable soil conditions.

Abstract

A method of improving crop yields by optimizing seed depth and a separation distance between seeds and fertilizer during planting into a field surface as soil conditions change between negative field portions and positive field portions of the field surface and the transitional field portion lying between the negative and positive field portions wherein the seed depth and separation distance between seeds and fertilizer is increased in adverse soil conditions and decreased in favorable soil conditions.

Abstract

A product distribution system for an air seeder includes a plurality of furrow openers and a plurality of product distributors mounted on an implement frame. Each product distributor comprises a seed container and a plurality of seed delivery conduits extending radially outward from the seed container. A seed meter apparatus is connected to receive the seed product from the seed container and operative to meter seeds of the seed product into each of the seed delivery conduits. A seed product dispenser is operative to convey a seed product from a seed product tank into each seed container, and is operative to maintain a level of the seed product in each seed container above a selected level. The product distributors are spaced across the width of the implement frame.
