Haifa SOP features high dissolution rate compared to other potassium sulfate products. At 20°C, typical quantity of 100kg per 1000 liter of water will dissolve in few minutes to yield a clear 10% solution, with virtually no insoluble residues.
Haifa SOP contains very low levels of chloride, which makes it ideal fertilizer for crops which are sensitive to this detrimental element. Haifa SOP, with its very low salt index (46 in index), is a recommended source of potassium where there is a risk of salinity build-up and in intensive cultivation systems, both protected and in open field.
Haifa SOP with its high sulfur content (18% S) is the fertilizer of choice for plants with high sulfur requirements, such as oilseed rape, sunflower, cabbage, onion, leek, and others.
Haifa SOP provides nitrogen-free potassium, which allows growers to schedule fertilization programs that match crop needs during stages of reduced nitrogen requirements.
