Unit price perPotassium (K) and sulfur (S) are two of the essential nutrients that plants require to achieve optimum growth and reach their maxi-mum potential. Nearly every major plant physiological function depends on one or both of these nutrients and here, in the highly available water-soluble sulfate form, we offer a high performance solution grade powder that growers can apply with confidence. Designed for efficient delivery and immediate uptake, this 200 mesh powder can be used in reservoirs, fertigation, drip irrigation or spray applications.
See package for application rates. Down To Earth Solution Grade Potassium Sulfate 0-0-50 is approved for use in organic crop production by the USDA National Organic Program (NOP). CDFA Organic Input Materials Registered and OMRI listed.
