I'm doing a project testing the effects of the presence of ashes into soil as a way to provide the minerals and nutrients pinto beans need to grow and I got the idea from your website of measuring my plants' growth through the root to shoot ratio. Even though I've researched a lot, I have not yet fully understood the measurements that I have found that in theory my plants will have. In a paper that I found whilst researching, it stated that beans grown in P-deficient soil had 1.95:4.33 grams whilst those beans grown in soil with sufficient P resulted in 2.36:5.66 grams. I have not been able to find any video or website that can explain to me those numbers. Do you guys know how it works?
Thank you so much.
