  • Patent number: 10219429
    Abstract: Liquid nutrients are continuously applied to a first group of rows of standing crops by pulling a drag hose from a reel located at one end of a field and between two crop rows with a boom having one end pivotally connected to an applicator and a tractor. The boom provides a liquid supply line from the drag hose to the center or one end of the applicator. At the opposite end of the field, the tractor and applicator turn 180° while the boom pivots to project from one end of the applicator to the drag hose. The tractor returns down adjacent rows back to the first end of the field with the boom projecting to the drag hose while the reel simultaneously retracts the hose between the two crop rows. The reel is moved axially to a third group of rows, and the steps are repeated.

    Abstract: The present invention relates to a knife for and a method of zero till or minimum till seeding and fertilizing. The knife is particularly adapted for dry land conditions producing minimum solid disturbance and very shallow operation. The knife has a high penetration angle preferably of 45 degrees which permits the blade to enter high trash surface cover with little tendency to plug due to trash accumulation. The blade has a forward angle of attack, the lower cutting edge advancing before the upper cutting edge, serving to make a clean cut in the soil surface without accumulating trash. Seed and/or fertilizer conduits are attached to or incorporated in the trailing face of the blade in which the outlets may be spaced for controlled placement of the materials. By the method a furrow is cut having a substantial transverse component in an operation with a substantial forward component.

  • Patent number: 7290491
    Abstract: The present invention relates to a knife for and a method of zero till or minimum till seeding and fertilizing. The knife is particularly adapted for dry land conditions producing minimum solid disturbance and very shallow operation. The knife has a high penetration angle preferably of 45 degrees which permits the blade to enter high trash surface cover with little tendency to plug due to trash accumulation. The blade has a forward angle of attack, the lower cutting edge advancing before the upper cutting edge, serving to make a clean cut in the soil surface without accumulating trash. Seed and/or fertilizer conduits are attached to or incorporated in the trailing face of the blade in which the outlets may be spaced for controlled placement of the materials. By the method a furrow is cut having a substantial transverse component in an operation with a substantial forward component.

  • Patent number: 7255049
    Abstract: A method for the subsurface application of fertilizers, biologicals, fumigants, non-fumigant pesticides or other chemicals to soil with reduced application rates. Discrete amounts of the materials are injected into the soil at numerous sites along a path during a pass through the soil. At the injection sites, the materials form diffusion patterns which may touch or overlapping with diffusion patterns of adjacent soil injections. The application of materials to soil in this manner maintains optimum efficacy with the use of the least amount of materials necessary per acre of soil.

  • Patent number: 7213523
    Abstract: A ground working apparatus for dispensing an agricultural additive to the soil is provided. The apparatus is mounted to a tool bar that is operable to be towed across an agricultural field. The apparatus includes a coulter blade in combination with a knife element, and a conduit attached thereto operable to dispense the agricultural additive in the soil. The knife element and the coulter blade characterize a gap therebetween. The gap is defined by a forward edge of the knife element having a radius of curvature that is less than a radius of curvature of the coulter blade. The conduit in interchangeably attached by at least one conduit mount plate at the knife element.

  • Patent number: 7152539
    Abstract: Disc openers (14) for use with an air seeder (10) are configured for seeding and fertilizing a field (G). The opener (14b) broadly includes a coulter disc (20), a seed boot (24), and a fertilizer injector wing (26). The fertilizer injector wing (26) is configured for fixed attachment to the seed boot (24) and broadly includes a body (48), including an angled outboard portion (56), a toxic fertilizer injector (50), and a non-toxic fertilizer injector (52). The opener (14b) with the fertilizer injector wing (26) is configured to place the seed row (S) and the dedicated fertilizer band (DB) at an optimum geometric positional alignment relative to the seed row (S), in a single, low soil disturbing planting pass without disrupting the seed bed (BS). In alternative wings (300 and 400), the sufficiently safe geometric positioning is accomplished by the force of delivery of the fertilizers (N and P) coupled with an offset angle (OA) defined between a fertilizer injection axis (AF) and a seed outlet axis (AO).

  • Patent number: 6966270
    Abstract: A seeding tool for depositing seeds and fertilizer within a furrow including a knife opener having a liquid wing projecting from the side thereof for providing and maintaining spacing between the seeds and fertilizer. Preferably, the liquid wing is a tungsten carbide insert secured to the side of the knife opener, and has a wing shaped structure which is shaped and sized to space the fertilizer apart from the seeds, to protect the end of the tube from which fertilizer is dispensed, and to present a small leading surface which displaces the soil easily and presents minimal resistance. Preferably, the largest, side surface of the liquid wing insert is inclined toward the side of the knife opener from a widest lower, rear member adjacent the end of the fertilizer tube to a narrower top, front member near a leading end of the knife opener.
