Water-soluble potassium sulfate for nutrition of all crops.

Combines potassium and sulfur, two nutrients needed for plant growth. Haifa SOP is the recommended source of potassium in cases where soil pH needs to be lowered, sulfur is needed, or when nitrogen N dose limitation is required (e.g. at the end of the season). 

Provides concentrated nutrition available for plant absorption. Increases plant resistance to drought, frost, insects and diseases, thus improving yield and quality.
