That is true. But I guess most “fresh” fertlizer has to be cured for a year or so before becoming useful. It’s too hot and burns up the vegetation.
Stupid side story...I bought some chicken manure at the nursery several years ago. It was in a plastic bag. The stupid part of the story is that I failed to get it out of the trunk of the car for 24 hours...during the summer. I really thought I was going to have to sell the car. The stench was horrible...and the plastic bad deteriorated!
I use fresh horse manure in my raised beds. The plants love it. Chicken manure definitely needs to be decomposed, and it's wise to let cow manure sit for a while or you'll end up with toadstools everywhere.
LOL We all learn some lessons the hard way..Horse, goat, sheep and probably a few others can be plowed under without waiting, but my neighbor had cows and he piled up cow manure for the following year....but cow pancakes are sloppy like mud pies....they would just drip off a shovel if real fresh....(I think) :o)
