On-farm Evaluation of Potassium Chloride using Combine Yield Monitors

The addition of potassium (K) fertilizer to starter fertilizer blends is becoming a common practice in many areas of western Canada with high soil test K levels. Specific crops, such as malting barley and high yielding spring wheat, are commonly cited as examples of crops that benefit from this starter K. On-farm replicated strip trial projects were initiated to evaluate crop response to starter potassium chloride (KCl) application with the use of combine yield monitors.

    Work with farmers who have yield monitors and GPS to establish K strips in high and low K fields and monitor them over a period of time to determine when and where responses may be obtained.
