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.
