"When I add up the live weights, exclusive of roots, estimated by soil biologists, I find more living biomass below the ground than above it, amounting to the equivalent of 12 horses per acre. The soil organisms consume oxygen from the soil air and give off carbon dioxide, and the summation of the multitudes of respirations characterizes the metabolism of a soil individual. Hence I designate soil as a living system."
---(Hans Jenny, "My friend, the Soil", Journal of Soil and Water Conservation, 1984, p. 160)
