Haifa SOP fertilizer is a potassium sulphate fertilizer for Nutrigation™ of all crops. It combines potassium and sulfur, two nutrients essential for plant growth. Haifa SOP is a recommended source of potassium where soil pH needs to be lowered, when sulfur is required, or when N application rates should be limited (e.g. at the end of the season).
Providing concentrated nutrition, readily available for plant uptake. It enhances plant’s resistance to drought, frost, insects and diseases, thus improving yield and quality. Haifa SOP helps gaining higher nutritional value of crops, better taste and appearance, and improved suitability for transport and storage. Haifa SOP is a crystalline product, fast dissolving, highly soluble and virtually free of chloride.

Haifa SOP dissolves rapidly
Haifa SOP features high dissolution rate compared to other SOP 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 is ideal for salt-sensitive crops
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 is rich in sulfur
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 decreases the pH in the stock solution
Haifa SOP is a nitrogen-free source of potassium
Haifa SOP provides nitrogen-free potassium, which allows growers to schedule fertilization programs that match crop needs during stages of reduced nitrogen requirements.
