The Chinese are well aware of the importance of maintaining the fertility of the soil. Composting is a way of life as the Chinese save all organic matter to use as natural fertilizer or as animal fodder. In many instances a village farmer is assigned the task of gathering up deposits of manure from stray village animals and placing them in the communal compost bin. Through such care the Chinese have kept up the fertility of their soil which would otherwise have been depleted long ago by such intensive use.
