If you have a place to store the manure, you can also employ what is called "sheet composting". That simply means that manure is applied to the garden or field by simply spreading it all over the soil, from October to February directly. Another method is to trench compost which is a long trench or trenches in the garden, approximately 6-9" deep into which the leaves, manure, etc are placed during the same off season time period. There are many alternative ways to accomplish the goal.
