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