These create lots of small air gaps. Water drains through them easily so it usually feels dry. Clay soil is usually sticky and has small particles. They contain very few air gaps and water does ...

To test this hypothesis, an aeroponic system was built that contained Martian simulant (Mars Mojave Simulant-2; MMS-2), inert sand, and a no-filter control to evaluate the in-line filters for ...
