Single vs. Split Potassium Applications for Coastal Bermudagrass1

Splitting potash applications, however, consistently increased available potassium in the soil over single applications. Luxury consumption of potassium can be reduced by making split applications of potash at no more than half the nitrogen rates on soils kept low in available potassium.
