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.

Objectives
- 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.
