Published in the Journal of Plant Ecology, the study used X-ray technology to examine tiny channels or "macropores" in the ...

The research found that soils with more macropores facilitated easier water movement, which is especially beneficial for wetland environments. Lumeng Xie, principal author and a visiting Ph.D ...
