The advantages of potassium nitrate
Haifa Bonus™ formulas are based on Haifa’s Multi-K™ potassium nitrate. Potassium nitrate contains 100% plant macronutrients: potassium (K) and nitrate-nitrogen (N-NO3). Plants absorb both the potassium and the nitrate rapidly, in a balanced manner. The similar uptake rates of these two ions improve the movement of both potassium and nitrogen in the plant, thus enhancing plant nutrition. Potassium nitrate is free of chloride, sodium and any other elements which are detrimental to plants.
