1995 Annual Interpretive Summary
Potassium cycling in the wheat/corn soil/plant system, 1995
Plant available soil K was increased by 24 percent and 38 to 55 percent after being amended with 113 and 225 kg K2O/ha, respectively. The K input/output balances for the wheat/corn rotation showed that with the crop removing 261 kg K/ha, there were soil K deficits of 95 and 48 kg K/ha for the 113 and 225 kg K2O/ha potash treatments, respectively.
