  1. Manure Management • Each 1000 pound horse produces 9 tons/year • That’s equal to 50 lbs per day • Urine amounts of 6-10 gallons also add 50 lbs per day • Nutrient Value per Ton • Nitrogen-19 pounds • Phosphorus- 14 pounds • Potassium-36 pounds • One ton of horse manure equal to 50 lbs of 14-5-11 fertilizer

  2. Manure Management • Horse Management Programs • Graze full time on pasture with supplemental winter feed, manure is not collected, spread by harrow during growing season • Confined system with manure being removed from pens daily, manure is composted or stockpiled for later land application

  3. Manure Management • Grazing Management • Rotational Grazing benefits distribution • Harrowing spreads manure, reduces fly count and speeds decomposition of manure

  4. Manure Management • Daily Collection Options • Stockpile and apply to land require adequate storage area with runoff control and keep 150 feet away from stream or lake • Try not to apply to pasture to keep parasites down • Composting • Reduces volume by 40-60% • Take proper C:N ratio of 25:1 to 30:1

  5. Manure Management • Composting • Horse manure has a C:N ratio of 50:1 • Must add nitrogen to mix • Good sources are grass clippings, hay, or fertilizer sources of Nitrogen • Moisture balance is critical • Keep moist but not soggy • Aerate by turning regularly

  6. Manure Management • Composting • Apply compost to land at the rate of 10-15 ton per acre • Make sure internal temperature of compost pile reaches 145 degrees F. • Use compost bin • Construct from wood • Round bales • Use 5-gallon of fertile soil or mature compost to start • Should take 6 months to breakdown
