It is recommended to use MKP as a source of phosphorus and potassium where nitrogen levels should be kept low. Because of its unique characteristics, MKP can be applied through any irrigation system and on any growth medium. Unlike phosphoric acid, MKP is moderately acidic. Therefore, it is not corrosive to fertilizer pumps or to irrigation equipment.
MKP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++) or magnesium (Mg++). To apply 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.
Field-crops and vegetables: On young leaves, spray 14.3kg/Ha. MKP is recommended in most crops. On mature leaves and more tolerant crops, spray 21.4 kg/Ha. May be applied.
|Citrus||23.8-28.6kg/ha.||2-3 successive monthly sprays at early fruit development, starting 1 month after fruit-set|
|Stone fruits||14.3-21.4kg/ha.||2-4 applications from fruit-set to fruit coloring|
|grapes||14.3-21.4kg/ha.||1 application during fruit-set, 1 during ripening|
|Bananas||14.3-21.4kg/ha.||2-6 applications with the application of pesticides|
|Olives||23.8-28.6kg/ha.||application in early spring for flower induction and fruit setting,|
