Dairy Farming

It is agreed that the conservation of the fertility of the soil is the greatest problem of agriculture. The fact is established that it is possible to maintain the fertility of the soil where grain crops are sold from the farm. It is, however, certain that it is seldom done. So far, in our American history, grain selling has meant selling fertility that has been stored up in the past ages; and it has been followed by farmed-out soils and unprofitable agriculture. On the other hand, we find farms in almost every locality — and even entire countries can be pointed out - where the fertility of the soil has been vastly increased by livestock farming.
