ABSTRACT:
A multi-function draft implement for opening, seeding, and fertilizing is disclosed. The implement provides a vertical knife opener for creating a vertical trench in the ground, a horizontal sweep for opening a horizontal swath in the ground and creating a seed-supporting shelf. The seed-supporting shelf thus created allows the seeds to be deposited on the shelf on either side of the vertical trench. Fertilizer can be placed in the vertical trench and the ground is replaced over the shelf-supported seed and fertilizer. In one embodiment, the vertical knife is biased with respect to the horizontal sweep and depth-controlling ground-engaging wheels are provided for controlling the depth of the planting sweep. In another embodiment, the vertical knife and the horizontal sweep are in adjustable fixed relation. The implement allows for no till, minimum till, and conventional till planting operations with precise seed placement and a single-pass multiple ground preparation seeding, fertilizing, and herbicide application. The planting sweep allows seed placement in parallel paired rows in proper position with the deposited fertilizer in the trench between the rows to maximize yield. Depth control is provided with parallel linkage and the use of ground-engaging packer wheels, colter wheel, or a combination. Methods of single-pass and minimum tillage fertilizing and paired row planting are also disclosed.
