Key Growing States Facing a Potassium and Phosphorus Deficit

Robert Mullen Ph.D.

In a recent update to the industry’s only nutrient balance analysis, Dr. Mullen reveals that over the last 40-plus years, nutrient removal trends have outpaced consumption across much of the country. As a result, many key growing states now face a K and P balance trend deficit. The record yields many growers have recently enjoyed may make the warning signs appear less urgent. However, Dr. Mullen emphasizes this is an issue to be mindful of today, cautioning growers that if these trends continue, future yields and income-per-acre could be compromised.
