How much manure per cubic yard of soil?
I plan to mix some manure in with my soil for my containers. The question I have is home much per cubic yard of soil. I read a lot regarding per square foot but not by volume.
I do not know from what the manure is from but probably horse or cow it is ages 1-3 years and not sure if it has straw or saw dust in it. The soil composition is pretty much, clay, sand, some peat, some vermiculite, small gravel, my towns compost which seems mainly of grass, leaves and ground up twigs and branches.
I probably have about 4-5 yards of soil, and I would like to put in an appropriate amount of manure but can't seem to get an accurate assessment.
If you have any thoughts I would really appreciate it.
