Down to Earth Potassium Sulfate 0-0-50 | 1lb - OMRI Listed - (Case of 6)

200-Mesh Soluble Potassium Sulfate for Salt-Sensitive Crops, 1lb

Potassium chloride (muriate of potash) is the cheaper way to add potassium, but its chloride content raises soil salinity faster than some crops can tolerate. Down To Earth Potassium Sulfate 0-0-50 delivers the same potassium in a sulfate form instead, ground to 200 mesh for rapid dissolution in reservoirs, fertigation lines, and drip systems without the salinity concerns that come with chloride-based potash.

The 1lb size, sold as a case of six, is convenient for growers who apply potassium sulfate through irrigation or fertigation systems, or who want a concentrated supply for targeted potassium and sulfur delivery.

Key Features & Benefits

• 0-0-50 high potassium — provides 50% potassium in a highly water-soluble sulfate form.
• OMRI Listed — approved for certified organic production.
• Solution-grade 200 mesh powder — ultra-fine grind for rapid dissolution and suspension in water.
• Sulfate form reduces salinity concerns — delivers potassium without raising soil salinity as sharply as chloride-based potash.

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

This fits organic growers, market farmers, and home gardeners applying potassium and sulfur through liquid delivery systems who want water-soluble supplementation without switching to granular soil amendments or chloride-based potash.

About Down To Earth Potassium Sulfate 0-0-50

Potassium Sulfate is one of the solution-grade minerals Down To Earth Distributors packages at its Eugene, Oregon facility, part of an OMRI Listed catalog the company has built since 1977.

Frequently Asked Questions

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

It's a solution-grade 200 mesh powder designed for liquid delivery through reservoirs, fertigation, and drip irrigation, dissolving in water for immediate uptake. Granular amendments are broadcast onto soil instead.

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

Yes, this Potassium Sulfate carries an OMRI Listing, so it's an option for certified organic production. The listing applies to this solution-grade, 200-mesh formulation specifically.

How is it applied through drip irrigation?

Drip irrigation, fertigation, and reservoir application are all suited to this formula. Its 200 mesh grind lets it dissolve fully and move through irrigation lines without settling or clogging emitters.

Why choose potassium sulfate over potassium chloride (muriate of potash)?

The sulfate form doesn't raise soil salinity as sharply as potassium chloride, making it preferred for salt-sensitive crops. Both supply potassium, but the accompanying ion (sulfate versus chloride) makes the practical difference.

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

Yes, spray application is an option in addition to fertigation and drip irrigation use. Check the current label for the correct dilution and rate for whichever application method you choose.
