Drainage layers really *do* reduce water retention

This has been a hot topic for a long time, but there have never been any formal experiments on the effects of drainage layers. I just had a piece of research published which found that drainage layers usually reduce water retention, and almost never make it worse. In short: they do work to improve drainage.

I hope it's okay for me to share the link to the research study (I don't make money from this, I just want people to have good information!)... https://doi.org/10.1371/journal.pone.0318716

Hey dear,

Can you please tell how you posted your question? I didn't find that option. I want to ask a few questions.

Thank you
