What Makes This Product Stand Out
If you need a potassium fertiliser that can be used in a variety of application techniques and you don’t want to risk crop harm, this product is the answer.
The high quality (≥98%) guarantees that you obtain the highest possible potassium absorption with the lowest possible contaminants. It competes head-to-head with traditional potassium sources at >50% potassium concentration – but without the chlorine that is detrimental to chlorine-sensitive crops such as citrus and tea.
The product has low salt index (about 90) and low electrical conductivity (EC) and may be used in larger doses without causing salt stress. This is a great benefit when dealing with sensitive crops or soils prone to salinity.
By anti-caking technology the agglomeration rate below 5% is possible, which solves one of the most prevalent concerns in storage. The uniform particle size also guarantees consistent batch to batch spreading outcomes.
Application Scenarios
High Value Crop Foliar Spraying
Potassium formate foliar fertiliser is commonly used for grapes, cotton and greenhouse vegetables. It may be sprayed at 0.2%–0.5% dilution (50–100 g per mu) without the danger of phytotoxicity due to its low EC value.
Apply 2–3 times in the blooming and fruit growth periods. This is particularly good for increasing Brix (sugar content) and enhancing fruit colour – key quality criteria for export-class fruit.
Drip Irrigation & Fertigation System
This device works well with drip irrigation systems for precision agriculture, particularly in dry or saline environments. Dilution: 1%-2%. Application: 10-20 kg / mu, once every 10-15 days.
It will not cause clogging of emitters with different water hardness unlike the calcium sulphate generating fertilisers. It also remains totally in solution at sub-freezing temperatures, making it a reliable choice for early season cold-soil applications.
Manufacturing of Liquid Fertilisers
It is the basic raw ingredient for clear liquid fertilisers such as 0-0-30 or 0-0-40 formulations in B2B manufacture. Its solubility enables producers to generate super-concentrated solutions that are stable under temperature variations, unlike low-solubility alternatives like K₂SO₄.
Blending of Compound Fertilisers
5%–10% by weight in complex fertiliser mixtures. It is compatible with nitrogen and phosphorus components, combines uniformly, and does not react or separate. This adaptability makes it a suitable raw material for fertiliser producers that are building bespoke NPK formulations.

FAQ
Q: How much potassium does your product contain?
A: The concentration of potassium is > 50%, and the total purity is ≥ 98%. It is one of the most concentrated sources of chlorine free potassium accessible for agricultural application.
Q: What is the price difference between potassium formate fertiliser and traditional potassium sulphate?
A: Potassium formate fertiliser is often in the mid-to-premium class, because to its greater purity, chlorine-free composition, and better cold-water solubility. But the high potassium concentration and its compatibility with fertigation systems may help minimise the total application cost. Please contact us for a formal price depending on your volume needs.
Q: Is this product acceptable as a water soluble potassium formate for the manufacturing of liquid fertiliser?
A: Yes. As a water soluble potassium formate it is fully soluble without leaving any trace, even at high concentrations. It is also frequently used as a basic ingredient for the manufacture of 0-0-30 and 0-0-40 clear liquid fertiliser formulations and stays stable even at sub-zero temperatures.
Q: Can it be used as a foliar fertiliser of potassium formate without burning the leaves?
A: Yes. Its salt index is low and the EC is low which make it acceptable for foliar application at 0.2% - 0.5% concentration. It is especially useful for delicate crops such as grapes, citrus, tea and greenhouse vegetables during blooming and fruiting phases.
Q: How many pieces is the minimum order quantity and lead time?
A: Standard orders are generally available within 5-7 working days. Stock products will be delivered within 24 hours. Please contact us to check availability and MOQ for your intended market.
Q: Do you provide OEM packaging and bespoke documentation?
A: Yes. Custom packaging, OEM labelling and multilingual compliance documentation (COA, MSDS, conformance certifications) are all available as per your specifications.
