ABSTRACT:
A mobile agricultural sprayer having a control system for controlling the amount of chemical additive added to a water stream from a mobile storage tank in response to a chemical additive concentration detector is disclosed. The mobile sprayer utilizes a mobile water storage tank and at least one chemical additive tank which communicates with the water to be sprayed at a point between the tank and the sprinkler heads. A pump draws water from the storage tank and directs it under pressure to the sprinkler heads. The chemical additive is typically added in liquid form, such as a solution or a slurry, at a point preferably upstream of the pump inlet while concentration is measured at a point between the point of addition of the chemicals and the sprinkler heads and preferably before the inlet of the pump. The concentration detector transmits information to a monitor which controls the amount of chemical introduced into the water to be sprayed.
