What He Said: P.V. Cardon

[Permanence in agriculture] is attainable – but only through the wise application of our expanding knowledge about the use of our land, capital, and labor in production and distribution.  It does not deny full use of the land to any generation of owners. It does require that each generation, in its turn, observe land-use practices that insure sustained production.  – P.V. Cardon  Our Aim: An Introduction in Grass The Yearbook of Agriculture 1948
