Gafsa rock phosphate is generally accepted as being the best ground mineral phosphate available, containing valuable minerals and trace elements.

SFD’s new life range, which has been very successful to date, has now been complimented with the ‘Powercrop Range’ of PK fertilisers whereas our New Life range contains both water soluble phosphate and Gafsa steady release phosphate, ideal for grass re-seeds and winter cereals. The Powercrop range contains 100% Gafsa as the phosphate source.

Powercrop 1, 2 & 3 can be applied in the autumn to a variety of crops such as established silage and grazing fields, then in the spring nitrogen can be applied to complement the system.
