Use K to Improve N Efficiency
Interactions among nutrients are extremely important. A summary of 4 years of Dr. Jay Johnson’s work at Ohio State University shows that increasing soil test K levels helps increase the amount of N taken up by the corn crop, leading to higher corn yields and leaving less of the N in the soil at the end of the season. This means more profit for the farmer, more return on investment in N, and less N available to cause problems in water supplies. Higher K means more efficient N use at all N rates tested. Encourage farmers to maintain high K soil tests as a way to maintain profits and reduce environmental problems. Everyone wins on this one!
