1. A method for applying a fumigant to soil, comprising the steps of:
- maintaining a diffusion product in a storage tank;
repetitively priming a reservoir with a predetermined amount of the diffusion product from the storage tank, and between priming steps, injecting the predetermined amount of the diffusion product into the soil through a plurality of injectors, wherein the number of injectors, the quantity of the predetermined amount of the diffusion product and the interval between priming steps is calculated to obtain a predetermined diffusion pattern of the diffusion product 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.
