You are right, up148. Using it isn't optimal. I have long had (via Cook College @ Rutgers U.) the understanding that the best manure for gardens and crops is horse manure = the "sweetest" (least acidic; least "hot") ; cow manure the next-best, kind of "sweet"; human and dog (because they eat, basically, what we eat) feces are far too "hot" to use, especially around seedlings and growing-plants, that putting manure too close to them will cause the plants to be burned.
The addition of manure as fertilizer to a garden belongs being done when first digging/plowing up the soil, so everything can be mixed together for more thorough assimilation (my word for the process) and creation of good soil.
When I authored and directed a Federal Govt. program, several decades ago, for the employment of inner-city youth, which involved clearing empty lots of debris and establishing community gardens, we had the custom of going to nearby
horse stables to gather
horse manure, since it was considered an optimum ingredient for soil we were trying to revive and enrich in empty lots around town.
Since I was a municipal official, we were able to open fire hydrants to water the gardens, using specific tools and adapters to connect to traditional garden hoses. The gardens were abundant, featuring Mustard Greens; Collard Greens; tomatoes; cucumbers, affording nearby residents more than one harvest and plenty of community pride and improved appearance. Temporary fencing constructed by the Parks Dept. kept kids playing, and critters and pets out sufficiently, as did vigilant neighbors.
