ABSTRACT:
A field tank-vehicle has a large reservoir for holding water or plant nutrients in water solution and/or suspension, and a plurality of relatively small auxiliary containers for holding water solutions and/or suspensions of herbicides, insecticides, hormones and other soil-treating chemicals. The apparatus includes vehicle-speed-responsive means for insuring uniform mixture application, and positive-action pumps for each feed line to insure accurate metering of each liquid to a mixer in the main line leading to a conventional sprayer boom. Each pump is driven from the vehicle-speed-responsive means by a variable-ratio speed-changer for metering the several liquids being combined, in desired proportions.
