How long until your horse manure is considered well aged or rotted enough to be used? I am new to all of this that is one reason for asking. I used to work for horse feed now its the other end product that I get, lol but seriously, I have one of those never ending supplies, some is spread out to dry up and some is hot composted with old hay or bad hay that can't be fed. There is no grain during the hot season in the feed so mostly its just grass hay. The cool season its alfalfa hay. Grain when feed is primarily oats and some bran. Wife founded a nonprofit for special needs kids and uses horses, etc. in her program. So the leavings arrive on a weekly basis. I might as well come out of retirement again and found a local manure movers union. Here I thought gardening for food would be easy. In the last three months have lost about four pant sizes, not that I had any to spare before. Anyway, would like to hear any advice about how long before the manure is considered good to use if it hasn't been composted. Thanks in advance.
