Soybean School: How soil test P and K impact yield

We know that phosphorus (P) and potassium (K) are needed in soybeans to achieve those high yields. But, what's the right soil test level of each of these macronutrients, what happens when there's too much or too little, and how does that level affect soybean yield?

To answer these questions, RealAg's Bernard Tobin was joined by Dr. Laura Lindsey, of Ohio State University, who recently presented on the subject at Ontario Agricultural Conference, earlier this month.
