is my hay considered brown or green
A local horse owner occasionally brings me bags of hay for composting. I don't know much about it other than it is what they rake up around the where the horse(s) feed inside the stable. It has occasional manure mixed in but is mostly all hay. It's dry and sort of light green colored hay. I'm wondering if this is considered a brown or a green for my compost pile.
I plan on asking the horse owner what kind of hay it is. From what I've read, there are about three types of hay typically fed to horses: legume (alfalfa) hay, grass hay, and grain hay. Depending on what type of hay this ends up being, which would be considered a "brown" and which might be considered a "green" for my compost pile?
