Subsurface soil injection method
First Claim
1. A method for applying a discrete, predetermined amount of a material into soil at each of a plurality of predetermined points in the soil, comprising:
- pressurizing the material in a storage tank;
providing an electrical signal to a switch, wherein responsive to the electrical signal the switch releases the predetermined amount of the material from the storage tank; and
injecting the predetermined amount of the material into the soil using a shank positioned at one of the plurality of predetermined points,wherein the switch is maintained in a closed state when the shank is positioned between the predetermined points in the soil, andwherein the material diffusing into the soil from each of the plurality of predetermined points provides a desired diffusion pattern of the material in the soil.

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.
