ABSTRACT:
This invention relates to a method and apparatus for injecting agrochemicals into the subsurface of the soil without tilling of the soil. A high pressure pump delivers the solution to be injected to a series of injection nozzles. The injection nozzles cause liquid jets to be formed which have sufficient velocity and narrow cross-section to inject into the soil. The injection nozzles are supported by a shield-pan which rides on the surface of the soil. The apparatus causes continuous injection from a plurality of nozzles. The shield-pan minimizes clogging of the nozzles. In the preferred embodiment, a second low pressure system is incorporated to broadcast spray the soil surface. This is a low-pressure system utilizing a boom with broadcast nozzles.
