Agree rabbit is better, used it a few xs myself, microbes galore! Will lifen up any plant party.
Rabbit manures are my fave too. I put 6 full feed sacks of rabbutmanure in my dep 42x8x2 bed every year. Super healthy. Takes care of all nitrogen needs for the season, since plants dont veg in there.
Now not all Nitrogen is the same. Hot, strong, composted etc? You guys sound like bro scientists!
The strongest manure by traditional fertilizer numbers that I can find is sea bird 12 12 0 or 11 0 0. Cow might top out at 6 sumthing sumthing followed by chx around 3-4 for fresh "hot". Rabbit is low numbers.
The factors to consider include plant size cause the nitrogen burn is really an extreme dehydration from a concentration gradient pulling water out of the plant.
Next is the actual types of molecular nitrogen compounds. Urea, ammonia or nitrate. They stimulate plants in different ways. Urea is hard to burn plants with, and there is organic sources of it too. Ammonia is the one to watch out for with younger plants. I stumbled upon a wet bag of bird guano, smelled like smelling salts. In the AACT it was more active, than using dry pellets. So I now activate the sea bird pellets before putting in the tea.
Nitrate usually doesn't cause burn. It will cause othet nutrient deficiency and is easy to build up in a season to toxic levels. Usually from going way overboard with cow or even horse. Nitrate isn't as easily made in the beginning of a fertilizer being used, nor the first form of nitrogen a plant would prefer. But it sticks well, adsorbs well to OM via CEC mode displacing fert cations. Microbes, especially bacteria grow and grow, the carbon rich fiber in cow or horse finally degraded to a point for mass consumption of microbes, who utilize the extra nitrate causing a massive population growth and a massive nitrate dump from their wastes.
So the best advice is know the size of your plant and its needs. Dont over do it. You can a lil more easier than dig out too much from your hole or pot.
