A chlorine and hydroxide-free liquid potassium solution. 2-1-6 has two major applications, it is readily combined with 9-24-3 to produce a complete planter time fertilizer and it is very effective as a foliar applied nutrient. Its usability provides immediate response, whereas conventional potash becomes available very slowly and cannot be used as a starter due to its high salt index. A major advantage of 2-1-6 is that it remains in solution until frozen.

Salt index is 6.8 compared to potassium chloride at 116; and potassium sulfate at 50.

Application rate:

4 US gallons per 100 pounds of potassium chloride or potassium sulfate.
