Excerpt from Fertilisers and Manures The use of some form of fertiliser is becoming more and more a mark of modern agriculture. Though many farmers, and among them some of our best, still profess to scorn all artificial manures and pin their faith on the dung made by their stock, they none the less are buying the elements of fertility - nitrogen, phosphoric acid, and potash - in the cakes and other feeding stuffs which they bring from some outside source and consume on their farms. It is the continual introduction of plant food from outside which distinguishes modern intensive methods of cultivation from the old farming. Prior to a period which roughly coincides with the foundation of the Royal Agricultural Society of England in 1838, the farmer, living on the inherent capital of the soil, was forced into a conservative system of cultivation, which by restoring in the dung the greater part of what had been taken from the soil by the crops, would reduce the losses from his land to a point where they would be more or less balanced by the natural recuperative processes at work in the soil. In consequence the level of production was low, and it was the discovery and introduction of artificial fertilisers and feeding stuffs - nitrate of soda, guano, the phosphates, cotton cake, maize, etc., - which enabled the British farmer to raise his output per acre by at least 50 per cent, during the reign of the late Queen.
