  • How does water move through soil?
    on May 16, 2016 at 5:07 pm

    In the basic water cycle, water falls on the land in some type of precipitation (rain or snow). It either is soaked into the ground or runs off into a body of water – storm water or natural. Eventually, it returns to the atmosphere. But the story about water movement in soil is complex. Soil scientists call this topic “soil hydrology.” Experts now explain how soil texture, soil structure, and gravity influence water movement. […]
