I was engaged in a lively discussion on another thread about the old topic of adjusting the pH of our nutrients. Their reasoning for
doing it seemed solely based on the fact that we grow in containers vs. growing in the field.
So, because I care about facts, I went searching for a study on the difference between field plants and plants in containers. Guess what...I found one!
Because we can't link to pdf files, I'm going to drop this research article here that (at least for peat-based growing media), the pH of the water also does not affect the plants GROWN IN CONTAINERS.
It states the following results:
1. "pH did not play a role in micronutrient availability from soilless mix components in containers."
2. "All species of plants in the mix with pH in the low 4 range were just as green and vigorous as those at 7.0 or approaching pH 10.0."
Don't believe the hype.
When I find a study like this for soil in containers I will let you know. Is there a reason the pH of the nutes would be
more important in soil than it is in peat mixes or even 80% sand?
