Excerpt from The Waste and Conservation of Plant Food From the foregoing summary Of the methods of waste of plant food it has been seen that in spite Of all the precautions of the farmer and the chemist, and in spite Of the selective absorption Of the soil, immense quantities of valuable plant food are carried into the sea, where apparently they are lost to agriculture for ever. But this is only an apparent loss. The economies of nature are so happily adjusted as to provide a means of grad ually returning in some form or other to the power of the farmer the plant food which has been apparently destroyed. It is true that this return will probably not be to the locality where the waste originally occurred, and it may not take place until after the lapse of thousands of years, but this is of no consequence. Provided arable lands in general receive in some way and at some time a certain return for the plant food removed, it is entirely immaterial whether this be the original plant food removed or other equally as good. The sea is the great sorting ground into which all this waste material is poured. The roller processes of nature, like the mills of the gods, grind exceedingly slow and small, and the sea becomes the bolting cloth by which the products of milling are separated and sorted out. As soon as this waste material is poured into the sea, the process of sorting at once begins. The carbonate of lime becomes deposited in vast layers, or by organic life is transformed into immense coral formations or into shells. Phosphoric acid is likewise sifted out into phosphatic deposits or passes into the organic life of the sea. Even the potash, solu ble as it is, becomes collected into mineral aggregates or passes into animal or vegetable growth. All these valuable materials are thus conserved and put into a shape in which they may be returned sooner or later, to the use Of man. In the great cos mic economy there is no such thing as escape from usefulness of any valuable material. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
