  • For the First Time in History We Have the Power to Crush Our Environment ©2008 Rodale institute
  • Inspirational Wisdom • “ A nation that destroys its soil destroys itself.” Franklin Delano Roosevelt • “Despite all our pretensions, we still are totally dependent on 6 inches of top soil and the fact that it rains.” Confucius • “Nature is the greatest gift of all!” “Soil has the ability to regenerate itself” Robert Rodale ©2008 Rodale institute
  • Let’s Think About the Problems ©2008 Rodale institute

  • One Solution is Organic Production Supported by Statistics Supported by Science ©2008 Rodale institute
  • Same Resources…… Different Philosophy ©2008 Rodale institute
  • Soil Health & Fertility • Soil is a complex, multi-component system of interacting inorganic and organic materials, and the properties of soil result from the effect of all these interactions. Healthy soil management – emphasizes the conservation and increase of soil organic matter – by maximizing the contributions of on-farm resources Conservation - Prevents Erosion (loss of Organic Matter) Cover crops Green Manures Composts Animal Manures ©2008 Rodale institute

  • Soil in Organic Systems • Higher corn and soybean yields in drought years • Increased soil C and N • Higher water infiltration • Higher water holding cap. • Higher microbial activity ©2008 Rodale institute
  • Organic Corn - 1995 Drought Better infiltration, retention, and delivery to plants helps avoid drought damage Organic Conventional ©2008 Rodale institute
  • Where Does Organic Stand In The Agricultural World? According to The 2007 Census of Agriculture: • In 2008 organic farms had an average of $217,675 in sales compared to $134,807. • Census Conclusion: Adding in cost of production organic farms are more profitable. ©2008 Rodale institute

  • Each square represents one year’s global emissions of carbon dioxide, measured by the weight of carbon it contains. The size of each square is proportional to the amount of that year’s emissions.

  • Proven Carbon Sequestration Air Human nutrition and health starts in the soil, from Light is the which plants energy draw their source nutrients Plants The soil microbial community provides the nutritional Soil building blocks that plants need to grow and thrive The soil‘s microbial “labor force“ incoporates carbon into the soil structure www.rodaleinstitute.org ©2008 Rodale institute

  • Mycorrhizal Fungi • Extends plant root systems • Produces erosion- resistant, carbon enriched soil • Provides mechanisms for soil biological carbon fixation • Slows decay of organic matter ©2008 Rodale institute
  • NITROGEN Chemical synthetic N fertilizer • produced by the industrial Haber-Bosch process • requires huge amounts of energy to create the 2939 PSI and 842ºF of heat • needed to industrially extract N from the atmosphere and hydrogen from natural gas. • The production of 1 kg (2.2lbs) of chemical N fertilizer burns the equivalent of 1 L (1.05 Qt.) of oil and 17.6 cubic feet of natural gas, releasing a great deal of carbon and other greenhouse gasses into the atmosphere ©2008 Rodale institute

  • Published Research The Myth of Nitrogen Fertilization for Soil Carbon Sequestration S.A. Khan, R.L.Mulvaney, T.R.Ellsworth, and C.W.Boast Univ. of Ill Conclusion: A half century of N fertilization has played a crucial role in expanding worldwide grain production, but there has been a hidden cost to the soil resource: a net loss of native SOC and the residue C inputs. This cost has been exacerbated by the widespread use of yield-based systems for fertilizer N management, which are advocated for the sake of short-term economic gain rather then long term sustainability.
