I have been looking into Manado, and I am starting to suspect that it is has a relatively poor CEC, based on the degradation to clays caused by fire as mentioned in <this paper>.
Leca (expanded clay balls) I would assume could have rather similar chemical properties.
Does firing clay have a significant impact on substrate CEC? Is this impact so profound that the substrate might as-well be inert?
What percentage CEC is lost during firing would you guess? Could it be 99% lost?
I was going to use it with my emergent plants. I have used it a few times before. All thoughts welcome.
Sorry if this has been asked before. Thank you 🙂
