Soil Information

Historically if you wanted to know what soil type and the description for it, it was necessary to go to the library, NRCS office or Coop Extension office to find the soil survey.  It is a book out of print now, but it has maps with outlines of the soils of that county and the descriptions that characterize those soils.  The USDA put the Soil Survey online about 10 years ago

and it is great unless the internet goes down. 

Toby O'Geen at UC Davis has taken the same information and repackaged it so that it is easier to use
