What it is / When to use

Chloride-free P-K source for fertigation and foliar programs

Monopotassium phosphate (MKP 0-52-34) is a fully water-soluble phosphorus-potassium fertilizer raw material, KH2PO4, CAS 7778-77-0, supplying P2O5 52% and K2O 34%. The white crystal is chloride-free with a mildly acidic 1% solution pH of about 4.6, making it a core P-K source for fertigation and foliar programs during flowering and fruit development.

  • What it is Monopotassium phosphate (KH2PO4, CAS 7778-77-0), a 0-52-34 fully water-soluble P-K raw material.
  • When to use Use it from flowering through fruit filling when the crop needs phosphorus and potassium without extra nitrogen; compare MAP 12-61-0 for vegetative stages.
  • Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.

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

Monopotassium Phosphate 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.
