With recent increases in price and increasing interest integrating new crops into our cropping systems, Oklahoma has seen a drastic increase in soybean acres. Additionally, with higher commodity prices many producers are pushing yields to levels not previously obtained. This has resulted in increased nutrient deficiencies in soybean production, potassium in particular. With this project, locations will be identified throughout the state that have low soil potassium. Additional sites will be found that possess high soil test K levels to use as a testing and application check. Trials will be applied that evaluate pre-plant granular applications compared to in-season foliar herbicides and in-season granular fertilizers.
