Abstract: The improved sprayer system of the present invention utilizes a docking drogue and probe assembly to quickly and easily allow refilling of the sprayer tanks with a material from an enlarged nurse tank. The coupling of the drogue and probe allows for fluid communication, as well as electronic transmission of material data to a processor in the prime mover. This processor software also receives input regarding field data and crop data, as well as feedback data from the sprayer regarding the material application. A GPS system on the prime mover allows for tracking the spraying operation, while a time stamp in the processor software tracks the timing of the spraying operation. This system thus allows for accurate accountability and traceability for the use of materials during the spraying operation.

Abstract: A system for automating the growing of crops, such as grapevines. Combinations of data from sensors local to a vineyard, and from optional remote stations and sensors, is combined with a control system to accurately control the dispensing of water and chemicals such as insecticides, disease prevention fungicides and fertilizers.
