Efficient and effective placement of crop inputs is an integral part of building and maintaining soil health and soil productivity. With the development of in-field guidance and variable rate technologies, tillage and crop input placement is manageable by the inch and pound, year after year. Zone tillage is a soil management and crop production system that fully incorporates these technologies to combine efficient use of resources with the high levels of productivity. To take full advantage of the ETS Zone Tillage™ system, in-field guidance is a necessity. Zone tillage, directed fertilizer application, and seed placement require reliable and repeatable positioning.
