We market garden and once the harvest is finished in late September, the manure gets spread directly unto the fields. We continue to spread all fall and winter, right from the chicken pens, directly to the soil. Once March comes, all applications of fresh manure must cease. The issue is pathogens. This is a serious concern.
During the the April thru September growing season, the manure is stockpiled, awaiting final harvest, then it too is spread and the cycle repeats itself.
Yes, manure can be "hot" for some plants, but pathogen safety needs to be of primary concern.
