NPK 0:0:50 FAQs

Have questions about our NPK 0:0:50 (SOP)? Here are answers farmers ask us most often.

How Is SOP Different From MOP?
SOP (Sulphate of Potash) supplies potassium together with sulphur and contains no chloride, whereas MOP (Muriate of Potash) supplies potassium as potassium chloride. SOP is therefore preferred for chloride-sensitive and high-value crops.
Which Crops Benefit Most From SOP?
SOP is especially beneficial for chloride-sensitive, quality-focused crops such as grapes, pomegranate, potato, tobacco and vegetables, where it improves quality and yield.
Will It Improve Fruit Quality?
Yes. By supplying potassium and sulphur without chloride stress, SOP supports better fruit size, colour, sugar (Brix), firmness and shelf life.
Can I Use SOP In Drip Irrigation?
Yes. This water-soluble SOP grade dissolves cleanly and is well suited to drip fertigation as well as foliar application.
