To determine the frequency of soybean yield response to potassium fertilizer across a range of soil test potassium levels and soil types; to assess the effectiveness of different combinations of potassium fertilizer rates and placements for increasing soybean seed yields; to investigate the capacity of Manitoba soils to retain applied potassium in non-exchangeable forms that might not be available to crops.
