    Default Horse Manure compost

    Started screening the HM compost piles yesterday. Needed some exercise & having good weather. Still frozen down 6" but got the thawed 6" screened & stored. Piles are over 1 yr old, I covered with plastic & let it cook were mixed 4 or 5 times & re-covered after each mix.. They quit cooking in Sept & froze in Nov. It has rocks from the way the farm I got it from stacks it on a gravel pad. Screening is good either way, I get the gravel, hooves, knives & other big stuff out of it. Fluff it one more time before stored I covered.
    Out of 30 yards I get about 16 or 17 yds of good compost.
    Storage area

    10 loads of a 3 yd trailer stacked & covered & cooking

    That's fantastic, MB! I've been wanting to compost horse manure for awhile, but I'm kind of worried about weed seeds. I grow enough weeds without planting more with the manure. I assume that if I composted a big heap that it would wipe out any weed seeds -- is that correct? Thanks for the pictures!

    If you turn it, it should reach 150-160 degrees and cook most seeds.
    It ain't about the # of pounds of meat we bring back, nor about how much we spent to go do it. Its about seeing what no one else sees.

    If you get the stall bedding with the manure, (it absorbs the urine & is real high in nitrogen to generate heat) any pile over 3 feet deep & wide should generate allot of heat. Mine get around 150f. When they start to cool, I mix them , get the outside layer to the middle & give it a light mist/spray of water. It will heat up again. I also cover mine to keep in moisture & heat (& the odor)
    Pretty much weed free compost. I screen mine due to it having rocks (loading & mixing on gravel), but really it's good to go.
    Pile it up fresh, in about 3 weeks, mix. In another 3 weeks mix again. Should be good compost in 10 to 12 weeks.
    I started mine In April & May & had good "done" compost mid August. About a 40 to 50% shrinkage.
    Damp, not wet is key.
