Agricultural Solid Potassium Formate

Agricultural Solid Potassium Formate — Chloride-Free Potassium Fertilizer for High-Efficiency Crop Nutrition

Agricultural Solid Potassium Formate (CAS No. 590-29-4, molecular formula HCOOK) is a high purity potassium fertiliser without chloride, developed to suit the needs of contemporary and sustainable agriculture. Produced by Shanxi Zhaoyi Chemical Co., Ltd. — A producer with over 30 years of expertise in the business and 150,000 tons of yearly production capacity – this product has potassium content ≥50% and purity ≥98%. It has a 0% chloride ion content and highly water soluble, providing a dependable potassium formate fertilizer grade solution to crop producers, fertilizer formulators and agricultural distributors worldwide.

Technical Specifications

What Makes This Product Different from Standard Potassium Fertilizers

Potassium chloride and other potassium fertilizers are frequently utilized, although they have a well-known drawback of chlorine build-up in the soil. Excess chloride ions may cause root burn, yellowing of leaves and severe production reduction for chlorine sensitive crops such as strawberries, grapes, tobacco, tea and potatoes.

Potassium formate for crops avoids this problem altogether. There are no chloride ions at all. It helps to create strong roots and consistent nutrient absorption without the chemical stress of chloride based alternatives.

In addition to safety, the formate anion provides a source of carbon energy that supports the activity of soil bacteria. Over time, this helps to improve soil structure and lessen the compaction that tends to come with long-term use of traditional fertilisers.

Key Product Characteristics

This chloride-free potassium fertilizer formate stands apart for several reasons that matter at both the field and formulation level.

High potassium bioavailability. The fertilizer has a potassium level of ≥50% and is completely water soluble therefore is readily accessible to the plant. Studies and field comments show that crop absorption efficacy might be 30% greater than the typical potassium fertilizer, which means you receive better benefits with the same application rate.

Very low impurity profile and very pure. Iron content is limited to ≤0.001%. Heavy metals (like Pb) ≤0.001%. This maintains the soil chemistry pure and helps you to meet organic agricultural requirements.

Increased resilience to stress. It has been shown that regular use also enhances the crop’s resistance to drought, cold and disease. Growers claim a 10-15% output boost when included into organized fertilization programs.

Neutral to mildly alkaline pH. aqueous solution has a pH of 7.0 to 8.5 which is non-corrosive to soil and will not interfere with natural soil ecology.

Low moisture content. The product has a viscosity of ≤0.5% and has good fluidity, does not clump during storage and handling, and is appropriate for manual and mechanical application methods.

Application Methods and Crop Suitability

One of the practical advantages of this product is its versatility. You can apply it through multiple methods depending on your irrigation setup and crop type.

• Foliar spraying — Quick correction of potassium deficiency, effective within 24–48 hours
• Drip irrigation / fertigation — Precise nutrient delivery directly to the root zone, suitable for high-value crops
• Flush application — Efficient for field crops and large-scale planting operations

It is totally soluble and leaves no contaminants, so it will flow smoothly through drip lines and sprinkler systems without clogging.

It is especially suitable for chlorine sensitive crops such as tobacco, grapes, strawberries, citrus, tea, potatoes and green vegetables. It is also compatible with organic fertilizer components and may be used into compound fertilizer formulas without compatibility problems.

Q: Which crops are most affected by potassium formate for crops?

A: Tobacco, grape, strawberry, tea, potato and citrus are best suited – those crops that are sensitive to chlorine. This is a safer and more effective option for these crops, which are sensitive to chlorine toxicity from standard potassium chloride fertilizers.

Q: How does the product compare with potassium chloride?

A: There are no chloride ions in this product unlike potassium chloride hence there is no danger of root burn or leaf yellowing in sensitive crops. It also has 30% greater absorption efficiency and does not promote soil compaction with continued usage.

Q: Is this product suitable for organic farming?

A：Yes. It meets national organic agricultural fertilizer standards and supports third-party organic certification testing. Its high purity (≥98%) and near-zero impurity profile make it compatible with organic production systems.

Q: Can this chloride-free potassium fertilizer formate be mixed with other fertilizers?

A：It is compatible with most organic fertilizer components and can be compounded into blended fertilizer formulations. It is recommended to conduct a small-scale compatibility test before large-scale mixing.

Q: What is the minimum order quantity, and can I request a sample?

A：Small-batch packaging (1 kg/bag) is available for trial evaluation. Normal packaging for commercial orders is 25 kg or 1,000 kg. Get in touch with us personally to talk about your specific volume requirements.

Q: How can I store the goods to maintain the quality?

A: Store in a cool, dry, well-ventilated warehouse away from heat and moisture. Avoid direct sunshine and hazardous substances. Shelf life 12 months under proper storage conditions.The low moisture content (≤0.5%) gives an excellent stability of the product over this time.
