Nutrient Dense Grazing
- 1. Nutrient Dense Grazing Lisa McCrory, Earthwise Farm and Forest Beginning Women Farmer Conference March 22 & 23, 2012
- 2. Landbase: 158 acres owned, 16 acres rented Open land = 24 acres; 23 pasture, 1 acre crop land
- 3. Hand-squeezed Raw Milk certified organic
- 4. Hand-squeezed right in the pasture
- 6. Sows and Feeder Pigs
- 7. Poultry: Heritage Turkeys, Meat birds, Layers
- 8. Layers and Turkeys hatched on the farm
- 10. Renewable Energy
- 13. Grazing has made tremendous improvements on our fields
- 14. Key Ingredients to a good grazing plan: Adequate rest in between grazings Clipping pastures when needed Providing water in every paddock Move the animals often (every 12-48 hours) Appropriate size of paddocks
- 15. Infrastructure Improvements • 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. Brontosaurus Hired in 2010 to chip up the debris (tree tops, stumps, shrubs on 4 acres or what was white and red pine
- 17. Field Management Clipping when needed Lime application Other amendments
- 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. 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. Keeping Good Grazing Records : Forward planning and historical records
- 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. 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. Micro Nutrients Solubor = 20% Boron Borax = 11% Boron Cobalt Sulfate = 27% copper Manganese Sulfate = 32% Manganese
- 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. Nutrients applied 13 acres of pasture - 1 ton/acre lime 10 Acres of pasture - 200# gypsum - 200# sulpomag - 10# solubor, 10# zinc sulfate, 15 # Manganese sulfate/acre, mixed with humates, (50% summer, 50% fall application
