Thirsty Plants Keep Deserts’ Subsurface Dry
From Science Daily. New research to be published this week by hydrogeologists at the University of Texas, Austin, shows that vegetation has been drying out desert soil since the last glacial maximum. This research has some interesting implications: Plants that flourish in arid areas after rains, might reduce water accumulation in soil should the climate shift toward wetter conditions. […] Because plants can maintain dry conditions, minimizing leaching of wastes into underlying aquifers, important implications exist for radioactive and hazardous waste disposal.
