• Solution-Grade 200 Mesh Powder — Ultra-fine 200 mesh powder for rapid dissolution and suspension in water.
• Provides Potassium and Sulfur — Delivers two essential plant nutrients together in a single application.
• Designed for Fertigation and Drip Irrigation — Formulated for use in reservoirs, fertigation systems, drip irrigation, and spray applications.

Who Should Use Down to Earth Potassium Sulfate 0-0-50

Potassium Sulfate 0-0-50 suits organic growers, market farmers, and home gardeners who apply potassium and sulfur through liquid delivery systems including drip irrigation, fertigation, and reservoir-based growing systems. It is particularly valuable for those who need water-soluble potassium and sulfur supplementation without switching to granular soil amendments.

Potassium and Sulfur as Plant Nutrients

Potassium is a primary macronutrient involved in water regulation, enzyme activation, and overall plant vigor. It plays a role in fruit quality and the movement of sugars within the plant. Sulfur is a secondary macronutrient required for amino acid synthesis, enzyme function, and chlorophyll formation. Potassium sulfate provides both nutrients together in a highly water-soluble form. The sulfate form of potassium does not raise soil salinity as sharply as potassium chloride (muriate of potash), making it preferred for salt-sensitive crops.

Frequently Asked Questions

What makes Potassium Sulfate 0-0-50 different from granular potassium amendments?

Potassium Sulfate 0-0-50 is a solution-grade 200 mesh powder designed for liquid delivery through reservoirs, fertigation, and drip irrigation. It dissolves in water for efficient delivery and immediate uptake, unlike granular amendments that are broadcast onto soil.

Is Down to Earth Potassium Sulfate 0-0-50 OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

Can it be applied through drip irrigation?

Yes. It is designed for use in drip irrigation, fertigation systems, and reservoir applications. The 200 mesh particle size allows it to dissolve and be delivered through irrigation lines.

What nutrients does Potassium Sulfate 0-0-50 provide?

It provides potassium (K) and sulfur (S) — both essential plant nutrients. Potassium supports plant vigor and fruit quality. Sulfur supports amino acid synthesis and enzyme function.

Can Potassium Sulfate 0-0-50 be used as a foliar spray?

Yes. It can be applied as a spray application in addition to fertigation and drip irrigation uses. Follow current label directions for rates and dilution by application method.
