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.

Project Description
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. However, there are no research results to support this practice or recommendation by fertilizer dealers. It is argued that this type of crop response reported by farmers and dealers indicates that the current soil testing methods may need to be reassessed on these soils. 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.
