Excerpt from The Southern Planter and Farmer: Devoted to Agriculture, Horticulture and the Mining, Mechanic and Household Arts; May, 1874 I have repeatedly found that on peaty soils, abounding in humic and similar organic acids, and showing an acid reaction when tested with blue litmus paper, and also on poor, purely sandy soils, the worst super-phosphates, that is to say, super-phosphate poor in solu ble phosphoric acid, have a decidedly better effect upon the crops to which they are applied, than super-phosphate rich in soluble phos photic acid. The latter, under these circumstances, indeed, sometimes do positive mischief. For all that, the business of treating raw phosphatic mineral materials with acid will not be revolutionized in a hurry; quite the contrary. It will grow as steadily in your country, and become more extensive from year to year, as it has in England and other countries of Europe.
