  3. Total Soil Erosion per Cropland Acre Natural Resources Inventory, USDA (2003)

  4. U.S. Erosion Iowa’s Share: 139,000,000 Tons Average: 5.4 Tons/acre

  5. WATER EROSION – BUTLER COUNTY

  6. THE MISSISSIPPI RIVER ROOT RIVER AFTER 2” RAIN

  7. Partial Budget

  8. Statewide No-Till average: 174bu/acre Corn

  9. WATER EROSION – WINNESHIEK COUNTY

  10. WATER EROSION – CHICKASAW COUNTY

  11. NRCS Estimate What is the value of the lost soil functioning?

  12. “there was still a decrease in yield not corrected by the higher amount of N fertilizer added” Fenton (2005) Erosional impact on organic matter content and productivity of selected Iowa soils.

  13. Stover Removal

  14. WIND EROSION – HANCOCK COUNTY

  15. Stover Removal

  16. Erosion Estimate

  17. Other Revenue Opportunities • .6 Tons CO2/year Value of 1 ton = $3.80 to $7.50 Additional Profit = $2.28 to $4.50 • Requires commitment ~5 years • Strip Till Included • Current Programs: • Iowa Farm Bureau • National Farmer’s Union

  18. Economics of No Till • We have a problem • Partial budgeting • Soil has Value ($6-10) • Stover has value • Practices can prevent erosion – saving $$ • Do conservation, get paid

  19. Questions? Andy Herringshaw Bremer Co. Floyd Co.
