Abstract
A field crop treatment system, characterized by a first treatment pipe submerged under the root system of growing field crops, and a second drain pipe submerged under the treatment pipe. The system is connected in such a manner that it can operate in several modes. Among the modes are a drainage mode wherein both pipes drain the water from a wet field; and an irrigation mode wherein the top pipe is used to irrigate at the underground level. In addition, the system may be used in various modes between complete drainage and complete irrigation to allow underground application of chemicals, herbicides and the like.
