Buy Monopotassium phosphate Fertilizer

Buy Monopotassium phosphate Fertilizer. Monopotassium phosphate (MKP) for sale (also, potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH2PO4. Together with dipotassium phosphate (K2HPO4.(H2O)x) it is often used as a fertilizer, food additive, and buffering agent. The salt often cocrystallizes with the dipotassium salt as well as with phosphoric acid. Single crystals are paraelectric at room temperature. At temperatures below −150 °C (−238 °F), they become ferroelectric.

 Monopotassium phosphate Fertilizer suppliers

We are suppliers of Monopotassium Phosphate (MKP) Horticultural Grade is a highly pure Phosphate fertilizer, which dissolves rapidly and completely. Our product has a limited caking sensitivity and is recommended during root and shoot development in early stages, up until flowering and early fruit set. The high level of Phosphate in our formula increases cell division and development of new plant tissue. The presence of Potassium plays an important role in protecting the plant from early stress, as well as providing a good support for the fruits in early fruit set.

Monopotassium phosphate Fertilizer Improves root and shoot growth Limits vegetative growth as of fruit setting Developed for fertigation in open field and greenhouses. Also suitable for foliar application monopotassium phosphate Efficient source of phosphorus and potassium for plants

Buy Monopotassium phosphate Fertilizer is Fully water-soluble Consists of 100% plant nutrients
Free of chloride, sodium and other detrimental elements for plants Safe for plants and humans: has a moderately low pH and low salt index Suitable for the Nutrigation, foliar application and fertilizer blends

 Monopotassium phosphate Fertilizer wholesalers

We are wholesalers of  nitrogen-free fertilizer, Buy MKP  fertilizer is the preferred source of phosphorus and potassium when nitrogen fertilization should be limited. For example, early in the growing season, when phosphorus and potassium are needed at high rates for the establishment of root system. Application of MKP fertilizer at the productive stages of sugar-rich fruit crops helps to increase sugar content and to improve the quality of these.

 Monopotassium phosphate Fertilizer for sale

We have MKP fertilizer for sale and can be applied in combination with other fertilizers to meet crop nutritional needs throughout the growth cycle. Its high purity and water-solubility make MKP an ideal fertilizer for Nutrigation (Fertigation) and for foliar application.

Additionally, MKP is suitable for preparation of fertilizer blends and production of liquid fertilizers.

Monopotassium phosphate Fertilizer Application Recommendations

Nutrigation Of MKP
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.

Compatibility of MKP
MKP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca++) or magnesium (Mg++). To apply Haifa MKP in combination with calcium or magnesium fertilizers, use two fertilizer tanks. If the system includes only one tank, apply the fertilizers at different times.

Quantitative Nutrigation of MKP
Each kilogram of Haifa MKP™ in the tank provides 520 grams of P2O5 (230g P) and 340 grams of K2O (280g K).

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

g/1000 liter water

Foliar Nutrition of MKP

Foliar application of  MKP is an optional supplement to soil fertilization at growth stages when high levels of phosphorus and potassium are required. An early season foliar application with  MKP promotes the establishment of a healthy root system.

MKP is an efficient suppressor of powdery mildew in susceptible crops (deciduous, vineyards, mango, cucumbers, melons, roses and others). Application of 1%  MKP mixed with systemic fungicides improves the fungicide efficiency and allows it to be used at reduced application rates.

MKP is compatible with most commonly used pesticides and fertilizers. However, it should not be mixed with calcium or magnesium fertilizers. Iron, manganese, zinc and copper must be in the form of chelates.

Field-crops and vegetables: On young leaves, spray concentration of 1.0%  MKP is recommended in most crops. On mature leaves and more tolerant crops, concentration of 2.0% may be applied.

Fruit trees:MKP

Crop Conc. Timing
Citrus 1-3% 2-3 successive monthly sprays at early fruit development, starting 1 month after fruit-set
Stone fruits 1-2% 2-4 applications from fruit-set to fruit coloring
Table grapes 1-2% 1 application during fruit-set, 1 during ripening
Bananas 1-2% 2-6 applications with the application of pesticides
Vineyards 2% 1 application during fruit-set, 1 during ripening
1% Every 2 weeks, starting when twigs are 10-14cm long until veraison, alternated with proper fungicide.
Olives 3-5% 1 application in early spring for flower induction and fruit setting,
2 applications during fruit development,
1 application on September during sizing and oil filling.
