What Kind?
I recommend goat, sheep, cow, chicken, and turkey manure. NOT HORSE! Horses are not full ruminants like goat, sheep, and cow, and therefore can spread weed seed in their manure.
Goat and Sheep: manure is drier than cow or horse manure. It has less odor, is easier to spread, and composts more quickly. Goat manure is also higher in nitrogen than horse or cow manure. Goat and sheep manure is very easy to work with as it is not as chemically hot as poultry manure.
Chicken and Turkey: manure is very high in nitrogen and contains a good amount of potassium and phosphorus. The high nitrogen and balanced nutrients make chicken manure one of the best manures to use. Chicken and turkey manure should sit for 9-12 months before being used on food crops.
I mix goat and chicken manure in my beds at a 75/25 ratio… I find that this gets the best soil/compost after sitting over winter.
