Jay-Mar - 0-52-34 Mono-Potassium Phosphate - 50 LB Bag

Multi-MKP is a fully water-soluble mono-potassium phosphate fertilizer, a highly efficient source of phosphorus and potassium for plants. As a nitrogen-free fertilizer, Multi-MKP is the preferred source of phosphorus and potassium when nitrogen fertilization should be limited. A common case is at early growing season, when phosphorus and potassium are needed at high rates for the establishment of root system. Application of Multi-MKP at the productive stages of sugar-rich fruit crops helps to increase sugar content and to improve the quality of these.

Multi-MKP can be applied in combination with other fertilizers to meet crop nutritional needs throughout the growth cycle. Its high purity and water-solubility make Multi-MKP an ideal fertilizer for fertigation and for foliar application. Additionally, Multi-MKP is suitable for preparation of fertilizer blends and production of liquid fertilizers. When applied as foliar spray, Multi-MKP acts as a suppressor of powdery mildew.

Application

It is recommended to use Multi-MKP as a source of phosphorus and potassium where nitrogen levels should be kept low. Because of its unique characteristics, Multi-MKP can be applied through any irrigation system and on any growth medium. Unlike phosphoric acid, Multi-MKP is moderately acidic (see table on the 1st page of spec sheet). Therefore, it is not corrosive to fertilizer pumps or to irrigation equipment.

Compatibility - Multi-MKP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++) or magnesium (Mg++). To apply Multi-MKP in combination with calcium or magnesium fertilizers, use two fertilizer tanks. If only a single fertilizer tank is available, apply those fertilizers at different times.

Quantitative Nutrition - Each kilogram of Multi-MKP in the tank provides 520 grams of P2O5 (230g P) and 340 grams of K2O (280g K).

Proportional Nutrigation - The phosphorus and potassium concentration in the irrigation water depends on the quantity of Multi-MKP in the tank mix, and on the injection ratio. Use the following table to calculate the quantity of Multi-MKP and the injection ratio needed to reach your target concentration in the irrigation water.
