While potassium is in tremendous supply within most soils, just a small fraction of one percent is plant-available. This means that for most turf a frequent application of soluble, plant-available potassium is required to maximize turf growth. Proper potassium nutrition is critical for plants for water movement, energy production and the activation of enzymes that promote overall plant strength. The combination of ionic potassium with phosphorus in K&P provides the optimum solution for strong turf and crops.
