Official State Soil: Antigo 
February 29th 


Francis D. Hole, professor of soil science and geography at the University of Wisconsin, wrote many songs about soil including this one:

Darkle, Darkle 
Darkle, darkle little grain. 
I wonder how you entertain 
A thousand creatures microscopic. 
Grains like you from pole to tropic 
Support land life upon this planet.
I marvel at you, crumb of granite!
