I have just discovered a source for free horse manure, but I am afraid to use it. I have two small boys who love to 'help' me in the garden and I know that fresh manure can contain pathogens. However, the stall that I can get manure from isn't fresh, but I am also not sure how aged it is either. I only know it isn't fresh because he piles the manure and lets it sit there and the pile that I cam pull from doesn't stink and it is crumbly, but I can't say that it is 4 months or 6 months old nor that it ever heated up. What do you think? Is there a way to tell how aged horse manure is? Are there any signs that say its done and can now be used in the garden?
If you saw my post about carrots, then you know I can really use this manure. I have heavy clay soil and have been gradually amending it due to cost....so this free manure could be a great addition!
