Nutrient Dense Grazing

  1. 1. Nutrient Dense GrazingLisa McCrory, Earthwise Farm and ForestBeginning Women Farmer ConferenceMarch 22 & 23, 2012
  2. 2. Landbase: 158 acres owned, 16 acres rentedOpen land = 24 acres; 23 pasture, 1 acre crop land
  3. 3. Hand-squeezed Raw Milk certified organic
  4. 4. Hand-squeezed right in the pasture
  5. 5. Draft Animals
  6. 6. Sows and Feeder Pigs
  7. 7. Poultry: Heritage Turkeys, Meat birds, Layers
  8. 8. Layers and Turkeyshatched on the farm
  9. 9. Off-Grid System
  10. 10. Renewable Energy
  11. 11. Organic Vegetables, Flowers
  12. 12. Grazing Management
  13. 13. Grazing has made tremendous improvements on our fields
  14. 14. Key Ingredients to a good grazing plan:Adequate rest in betweengrazingsClipping pastures whenneededProviding water in everypaddockMove the animals often(every 12-48 hours)Appropriate size of paddocks
  15. 15. InfrastructureImprovements• Water to every pasture (gravity feed), piping• Perimeter Fencing and other improvements through NRCS• Returning tree plantation back to pasture• Diverting water away from a pasture & barn and capturing it for use
  16. 16. Brontosaurus Hired in 2010 tochip up the debris(tree tops, stumps, shrubs on 4 acresor what was white and red pine
  17. 17. FieldManagementClipping when neededLime application Other amendments
  18. 18. Grazing was making a difference, But we wanted to ramp it up:• Become more self sufficient• Provide a more nutrient dense food for our livestock• Increase the biological activity in our soil
  19. 19. What I wanted to Address• Increase Disease & Pest Resistance• Increase Plant Species Diversity• Increase Forage Yields• Reduce Livestock Health Issues• Have longer growing season (productive life of plants)

  21. 21. Keeping Good Grazing Records :Forward planning and historical records
  22. 22. Important Conversions Important Conversion Values: PPM – Parts per million PPA = Pounds per Acre PPA = 2(PPM) There are 2 million lbs of soil in the top 6 inches of soil 500 lbs per acre = 11.5 lbs per 1000 sq feet 100 lbs per acre = 2.3 lbs per 1000 sq feet 20 lbs per acre = .46 lbs per 1000 sq feet 5 lbs per acre = 2 ounces per 1000 sq feet
  23. 23. Macro Nutrients available in natural forms: Magnesium Sulfate (epsom salts) = 20% Mg, 30% S Gypsum = 23% Ca, 19% S Sul-Po-Mag = 22%S, 22% K, 11% Mg Soft Rock Phosphate = 22% P, 20% Ca Hi Cal Lime = 38-40% Ca Dolomitic Lime = 30% Ca, 10% Mg P2O5: 75 PPM x 4.6 = 350 #/a
  24. 24. Micro NutrientsSolubor = 20% BoronBorax = 11% BoronCobalt Sulfate = 27% copperManganese Sulfate = 32% Manganese
  25. 25. Financials and Nutrients applied 18 tons lime @ $52/ton delivered = $940 2 ton SulPo Mag/Gypsum @ $550/ton = $1100 Micronutrients: Zinc Sulfate, Manganese Sulfate, Boron, Humates – applied at $75/acre = $750 Total amount invested on amendments for 2011 $2,790.00
  26. 26. Nutrients applied13 acres of pasture- 1 ton/acre lime10 Acres of pasture - 200# gypsum - 200# sulpomag - 10# solubor, 10# zinc sulfate, 15 # Manganesesulfate/acre, mixed with humates, (50% summer, 50%fall application
