Chapter 2 - Understanding the Basics: Buz's 'Fab-Five Facts of Healthy Soil' 

Just a comment on what I said around 0:50 that there are about 19,000 soil series in the US. I was reminded by friend and Soil Scientist Dave Hoover from the National soil Survey Center in Lincoln, Nebraska that there are now in fact 22,364 established soil series in the country!

Really appreciate what you do :)
