Abstract
THE extent to which the phosphatic fertilisers have dominated the outlook of farmers all the world over is well seen by the fact that when a country first embarks upon anything approaching a large scale use of artificial manures, it is the phosphatic fertilisers that are almost invariably employed, to the practical exclusion of all others. This is understandable, and within certain limits entirely reasonable: for when rainfall and sunshine are adequate, and where leguminous plants can thrive abundantly, a deficiency in phosphates is often the sole limiting factor to greatly increased production, and under these conditions phosphates frequently occasion results of such a pleasing magnitude that the farmer is, perhaps naturally, not in a hurry to look for methods of still further increasing his productivity—although, of course, it seldom happens that the addition of phosphates is all that is necessary to produce the highest yields obtainable.
