RTK

Since 2005, we have been using Global Positioning Systems (GPS) on our tractors, sprayer, and combine.  There are different levels of accuracy and the highest level is called RTK.  RTK is sub-inch accuracy pass to pass.  RTK stands for Real Time Kinematic satellite navigation.   Since going to this level of automatic guidance we have seen many improvements in yields, reduction of inputs, and increased efficiencies.  Having auto-steer also allows the driver to be much less fatigued at the end of the day and spend his time monitoring the planter more closely instead of driving.    In combination with this technology, we also implemented auto row and nozzle shut-off.  This technology allows the planter or sprayer to quit planting seed or applying fertilizer once it crosses into a area that has been previously planted or fertilized.  With the high prices of fertilizer and seed this saves us and our land-owners a substantial amount of money over the planting season by eliminating overlap.  Another benefit with the guidance is having controlled traffic in the field which helps to control compaction caused by multiple trips over the field.
