Discover Soils from the Ground Up!

Eath Week hands 2012.So what do you know about soil? Well, you’re about to know even more. Check out the following facts, then click on the hotlinks to get more information from NRCS soils specialists, plus your free downloads.
 

  • There are more individual organisms in a teaspoon of soil than there are people on earth.
  • There is a community of organisms called a soil food web that live all or parts of their lives in soil. See if you recognize them.
  • Tilling the soil is the equivalent of an earthquake, hurricane, tornado and forest fire occurring simultaneously in the world of soil organisms.
  • Many soils are held together by a glue made of a protein produced by fungi.
  • The size of soil particles and pores in the soil influence how water moves through the soil. See how water goes with the flow.
  • Water and warmth on hillsides can make layers of soil on hillsides thinner than soil layers on level land.
  • It can take as long as 1,000 years for an inch of soil to form. Want some perspective? See what happened in history in just half that time. (The poster makes great wallpaper!)
  • More farmers and ranchers are managing for soil health by disturbing their soil as little as possible, growing as many different species of plants as practical, keeping living plants in the soil as often as possible and keeping the soil covered constantly.
