One was amended with 25% compost. The other was just screened topsoil.
Both products had their own chemistry to start out. The company published the most recent analysis on their website so you had an idea of what you were starting with.
We also sold their straight compost. I would have never told a customer to grow in the 100% compost because you could see the soluble salts precipitating on the edges of the pile after a rain followed by sun and dry days for a week.
If you go with your straight compost, you are rolling the dice without an analysis on it.

Got the compost from the city public works dept. They sent it in for analysis, I have all the paperwork, I'll have to look. Here is the test results from last year:
