I really don't know about container plant soil. There are probably better people to ask.

But I know you can't go wrong with some well-aged horse poop.

Aged horse poop ( over one year old ) is good fertilizer. Fresh Horse poop is "too hot" (too high in nitrogen) and will kill fresh plants. In Northern colder climes , fresh horse poop is used under glass ( Cold Frames)to maintain heat and temperature
for late Fall/ winter season and early spring to over-winter plants .
Fresh horse is known for nitrogen and heat production.
Aged cow is known for gentler , gradual nitrogen release, and soil amendments, and breaking up hard /clay topsoil, or addes to sandy soils .
