Albert Howard quotes:

The health of soil, plant, animal and man is one and indivisible.

Artificial manures lead inevitably to artificial nutrition, artificial food, artificial animals and finally to artificial men and women.

Fertility of the soil is the future of civilization.

The main characteristic of Nature's farming can therefore be summed up in a few words. Mother earth never attempts to farm without live stock; she always raises mixed crops; great pains are taken to preserve the soil and to prevent erosion; the mixed vegetable and animal wastes are converted into humus; there is no waste; the processes of growth and the processes of decay balance one another; ample provision is made to maintain large reserves of fertility; the greatest care is taken to store the rainfall; both plants and animals are left to protect themselves against disease.
