Professor William A. Albrecht’s enduring message preserved and presented for future generations. In this 1950s-era film, with introductory and closing remarks by Acres U.S.A. founder Charles Walters, Prof. Albrecht explains the high cost of inadequate and imbalanced soil fertility and how that “dumb animal,” the cow, always knows which plant is the healthier, even though we humans don’t see a difference with our eyes. A period film and is dated in style but timeless in message. Perfect for your group gathering. Copyright 1996, DVD, 26 minutes.
