SOP Sulphate of Potash 0-0-48 is a supplement specifically designed to be spread on lawns.

Featured Benefits

  • One 24 lb bag covers up to 12,000 sq ft
  • Analysis is 0-0-48 :: N-P-K
  • Great for lawns that are deficient in potassium

If you have a soil test that shows you are deficient in potassium (K) this is the perfect product to move you in the right direction. It is not designed to change the color of the lawn.

Sulfate of Potash (SOP) is a naturally occurring mineral that aids in overall plant vigor, disease resistance, and stress recovery. The analysis is 0-0-48 Sulfate of Potash which provides potassium in a low salt formula. This is a slow-release product due to being polymer coated which also cuts down on the dust that you may find with other products like this.

This coating also adds an element of controlled release to the product. If you have looked at other Sulfate of Potash products online, you will find they are very dusty and many times are not prilled for easy lawn applications.

If you are looking to correct a severe deficiency, you do not have to correct this all in one month. Here are the steps we recommend:

  • Apply SOP every two to three weeks
  • Retest after the 2nd or 3rd application (wait 45 days after the last application before you retest)
  • If you still have a deficiency, apply more SOP 0-0-48 the following season

You can apply this on both cool-season and warm-season lawns any time of year as long as the ground is not frozen.

Analysis: 0-0-48

Sulfate of Potash can be used on all grass types, such as the following:

Does 0-0-48 SOP need to be watered in?

  • Yes. We recommend that Essential-G be applied before 0-0-48 fertilizer

  • Yes. We recommend applying granular products before liquids. So you would apply 0-0-48 and other granulars, followed by your liquid products.
