What is it about?
This article focuses on two aspects (a) water redistribution due to local changes in the particle sizes in soil and (b) how this configuration can be used to relate the physical water transport by roots to the stems and eventually to the leaves.

Why is it important?
This study is useful in understanding the redistribution of moisture transfer at the surface and sub-surface as well. The study can be used to model ground water flow. It can also be used to model root-soil moisture coupling.
Perspectives
This is a simple study but with a NOVEL idea. The particle size contrast was carefully chosen and investigated in order to mimic the root-soil water coupling. Smaller particles (few nanometers) mimicked roots (or root hairs) while larger particles mimicked sand. Depending on the depth of the smaller particles, we mimicked grass-type limited roots and plants-type deep roots.
