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.
