This year Trimble purchased Entek, the company who manufactures GreenSeeker Technology.
Jack Gerhardt discussed the history of remote sensing.
GreenSeeker is a sensor technology that is mounted on a machine passing over the field. It has its own light source and provides instant geo-referencing enabling a sprayer (for example) to apply a variable rate product through a variable rate controller.
Dr Guy Lafond with IHARF at Indian Head, SK has been developing the alogrithims we have been using to vary the N rate on wheat. There are now 7 different alogrithims now available for Canadian crops.
We have had a few farmers working with GreenSeeker for several years. The technology has some advantages because cloud cover is not an issue and the maps are generated in real time.
Jack mentioned the GreenSeeker has been used for top dressing of N, rescue Nitrogen, Fungicides, Desiccants and 2 Step Zone Rx’s as well as other real-time apps for farmers.
The RT150 is a up to 3 sensors…while the RT200 4 or more sensors enables variable boom shut off and allows an applicator to perform Real Time VR.
We featured an article on GreenSeeker in the May/June 2009 issue of The agAdvance. Check it out at www.TheagAdvance.com.
The GreenSeeker is available in Canada through Pattison Liquid Systems of Lemberg, SK.
