Diamond K KMS 0-0-21.5 Solution Grade Potassium

Water-Soluble Potassium, Magnesium and Sulfur in One Input - 0-0-21.5 Analysis

Soils low in magnesium that lose nutrients to leaching are hard to feed with fast-dissolving sources. Diamond K KMS is a solution-grade potassium magnesium sulfate that dissolves more slowly than other magnesium and potassium sources. It supplies all three nutrients in sulfate form, with a 0-0-21.5 analysis and low chloride.

Each unit is sold individually, with a minimum order of 30 units. That makes it a fit for growers who run ground sprayers or irrigation injection on a regular schedule and buy in volume. Smaller operations should plan around the order minimum.

Key Features & Benefits

• 325 mesh grind — fine particles suit ground spray equipment and irrigation injection systems.
• Potassium, magnesium and sulfur together — one input covers three nutrients, at 21% potassium, 11% magnesium and 22% sulfur.
• Low chloride — a good match for crops that are sensitive to chloride but need magnesium.
• Listed for organic crop production — carries OMRI, CDFA and WSDA listings.

Who Should Use Diamond K KMS

Growers applying nutrients to soil through sprayers or injection systems, especially where magnesium is low and leaching is a concern. It is a soil-application product and is not described for hydroponic reservoirs.

Frequently Asked Questions

Q: What does 0-0-21.5 mean?
A: The three numbers show nitrogen, phosphate and potash content. This product has no nitrogen or phosphate and 21.5 in the potash position. It also supplies magnesium and sulfur.

Q: How is it applied?
A: It is designed for ground spray equipment or irrigation injection systems in soil applications. Follow the label and the technical data sheet for rates.

Q: Will it change my soil pH?
A: The manufacturer describes it as neutral in pH when applied to soil. It does not add acidity or alkalinity.

Q: Why does chloride matter?
A: Some crops are sensitive to chloride. This product has low chloride, so it can supply potassium and magnesium with less of that concern.

Q: Is it certified for organic production?
A: It is listed for use in organic crop production and carries OMRI, CDFA and WSDA certifications. Check current listings with your certifier before use.

Q: What does solution grade mean?
A: It means the product is ground fine enough to be mixed into liquid for spraying or injection. Here the grind is 325 mesh.
