The Daily Grind
- This publication/thesis shows that this red mud is very strong stuff, and can quickly change soil pH in small quantities. I will need to evaluate how it affects soil microbes and maize associated microbes. First, I think I will start a plant assay in magentas using similar amounts of the stuff mixed with both vermiculite/sand or normal EMBRAPA soil. Will try 0, 2, and 5 g (untreated) red mud /kg of EMRAPA soil OR sand/vermiculite mix tommorow to assay growth potential. 3 plants per magenta will be put in these combinations of soil to assay for survival.
