University studies show that 40-60% of yield increases are the result of soil fertility management. This includes applying the right product at the right rate in the right place at the right time – commonly referred to as the 4R's of nutrient management.
Dan Froehlich, Ph. D. Director of Agronomy explains the need for balanced crop nutrition: "We look at the soil as a big bank account. You put nutrients in and as the crop grows it's removing those, you take the grain off and it removes different nutrients and if you take out more than you put in, eventually you're gonna have to replace that so mining the soil is when you're taking more out than what you're putting back on."
