[...] Hopkins has shown that soluble phosphate can be got as a result of the normal processes of nitrification in presence of rock phosphate and although at present the practical application of this method has still to be worked out the obvious advantage of being able to dispense with the necessity of spending money on sulphur indicates the advisability of research into the possibilities of this alter
