Grade selection

Is MKP 0-52-34 the right grade for your formulation?

Monopotassium phosphate is a fully water-soluble P-K fertilizer raw material, KH2PO4, CAS 7778-77-0. The white crystal has typical P2O5 52% and K2O 34% values, contains no added nitrogen and is chloride-free. Its 1% solution has a typical pH of about 4.6.

  • Choose MKP when the formulation needs phosphorus and potassium without extra nitrogen, including flowering and fruit-filling programs.
  • Compare MAP 12-61-0 when the formulation also needs N 12% and a higher typical P2O5 value for rooting or earlier stages.
  • Confirm the lot with the current batch COA. Website figures are typical screening values, not guaranteed shipment values.

Applications

Where Monopotassium Phosphate fits

Confirm crop, rate, compatibility, and local label requirements before application.

Fertigation P-K

A core phosphorus-potassium source for drip and sprinkler fertigation, dissolving fully without residue at label rates.

Foliar sprays

Chloride-free with a mildly acidic 1% solution pH of about 4.6, commonly used in foliar programs at low concentrations.

Flowering & fruiting

The nitrogen-free 0-52-34 analysis supports flower bud differentiation, fruit set, and sugar and colour development.

Chloride-sensitive crops

Suits grapes, strawberries, tobacco, potatoes, and other crops where chloride-based potassium is restricted.

Compare with MAP

MAP 12-61-0 supplies N 12% with P2O5 61% for rooting and early stages; switch to MKP when nitrogen is not wanted.

Batch documents

TDS, COA, and SDS support procurement and formulation review.

Buyer FAQ

MKP 0-52-34 sourcing questions

When should I choose MKP 0-52-34 instead of MAP 12-61-0?
Choose monopotassium phosphate (0-52-34) when the crop needs phosphorus and potassium without extra nitrogen, typically from flowering through fruit filling when surplus nitrogen would push vegetative growth. MAP 12-61-0 supplies N 12% with P2O5 61% and fits rooting and early vegetative stages. Many fertigation programs start with MAP and switch to MKP at flowering.
Is monopotassium phosphate suitable for fertigation and foliar spraying?
Yes. MKP 0-52-34 is fully water-soluble and chloride-free, and a 1% solution has a mildly acidic pH of about 4.6, which suits drip, sprinkler, and soilless systems. For foliar use it is commonly applied at low label rates; confirm crop-specific rates and tank-mix compatibility with your local agronomist before spraying.
Is MKP safe for chloride-sensitive crops?
Monopotassium phosphate is a chloride-free potassium source, so it is widely used on chloride-sensitive crops such as grapes, strawberries, tobacco, and potatoes. With K2O 34% and no sodium ballast, it also keeps the salt load low in recirculating and soilless systems.
Are the P2O5 and K2O values guaranteed?
No. The P2O5 52% and K2O 34% figures shown here are typical specification values for buyer screening. The current batch certificate of analysis (COA) confirms the final assay, appearance, and quality values for the lot you receive; TDS and SDS are also available on request.
What should I include in an MKP 0-52-34 request for quotation?
Send the target grade, annual volume, destination port or market, packaging preference, and intended formulation or application route. RunziChem can reply with the current specification, available document set, and a quotation.
