| 41 | Minimum Till Seeding Knife | US11556904 | 2006-11-06 | US20070056488A1 | 2007-03-15 | Terry Summach; Bradley Summach |
| 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. A preferred embodiment includes a horizontal extension blade for cutting a horizontal swath at a shallow depth through weed growth. Conduits may be secured to the extension to allow greater separation and control of material placement. The knives may be arranged in overlapping configuration on the draw bar to affect weed cutting, seeding and fertilizing of a complete with of soil in a single pass. | ||||||

| 46 | Frozen topsoil plow | US09522941 | 2000-03-10 | US06328114B1 | 2001-12-11 | Allan Mason Ritchie; Ronald George Ritchie |
| A plowing implement particularly adapted for breaking up frozen topsoil to a desired and controllable depth includes a backer plate and scraping blade which are both at a swept-back angle to the direction of travel. The scraping blade is preferably made up of a plurality of chisel plates which are spaced apart in a staggered fashion. The implement includes depth control means comprising a depth control shoe that is vertically adjustable. | ||||||
| 47 | Process and apparatus for killing soil pathogens | US513206 | 1995-08-10 | US5622123A | 1997-04-22 | A.H.J. Rajamannan |
| A process and apparatus for sterilizing soil includes an implement including a plurality of subsurface tools having hot water nozzles mounted thereon and connected to a source of hot water. Hot water is injected into the top layer of soil as the implement is moved over a field. Stirrer tools are mounted on the implement rearwardly of the subsurface tools and extend into the ground for mixing the soil and hot water to thereby provide a uniform temperature to the soil. A foam applying system applies an insulating foam to the surface of the soil immediately after the injection of hot water into the soil. | ||||||
| 48 | Method of laying subsoil membranes | US734174 | 1976-10-20 | US4098089A | 1978-07-04 | Dan Zaslavsky; Gideon Sinai; Giora Biran |
| A method for laying subsoil membranes includes dragging a hollow cutting blade through the soil at a predetermined depth, providing a supply of sheeting to the interior of the blade and feeding the sheeting from the interior of the blade through an opening therein. The hollow blade has a cutting edge, a rear edge and an upper section having an upwardly sloping front portion and a downwardly sloping rear portion connected by a center portion. The bottom portion of the blade slopes in an upward direction from its front to form a release angle. The sheet material is fed out of an opening in the rear of the blade. | ||||||
| 49 | Combined plow and fertilizer dispenser | US429786 | 1974-01-02 | US3990662A | 1976-11-09 | Roy H. Wallace |
| A combined plow and anhydrous ammonia fertilizer dispenser wherein the ammonia tank is connected to the plow so as to be drawn over unplowed ground. Hose means lead from the tank to the individual plow blades and dispense fertilizer beneath the soil being turned over in the furrows. The hoses are held in position by novel wear-reducing clamps. A further embodiment combines a chisel plow and fertilizer dispenser. The plow blades have hoses mounted thereon by clamps. Some of the plow blades which are located rearwardly of other plow blades push the dirt into the furrows cut by the forwardly located plow blades and also cover the exhaust end of the hoses with dirt causing the fertilizer to be retained in the soil. | ||||||
