Sunnyvale, Calif.-Trimble said June 5 that it has acquired privately-held NTech Industries, Ukiah, Utah. NTech is a leading provider of crop-sensing technology that allows farmers to reduce costs and environmental impact by controlling the application of nitrogen, herbicide, and other crop inputs. The acquisition further expands Trimble’s ability to offer innovative field applications for farmers. Financial terms were not disclosed. NTech products use optical sensing and variable rate application to apply only the inputs needed to maximize crop yield. The GreenSeeker® nitrogen application system determines the health of a plant in real time and delivers the optimum amount of nitrogen. The WeedSeeker® automatic spot-spray system senses the presence of living plants, allowing targeted and controlled herbicide application. The systems are typically utilized with Global Positioning System (GPS) solutions and flow and application control products, both of which are supported by Trimble’s precision agricultural portfolio of products.
