What are soil surveys important?
Soil surveys: produce maps and soil descriptions that compile information about soils and landscapes where they occur
What is soil composed of?
Composed of solid, liquid, and gas, and diverse community of living organisms Solid: minerals and organic matter Minerals: quartz, mica Liquid: contain chemicals dissolved from mineral phase or entered through soil surface Found in spaces between the solid particles Gas: dominant influence on heat, water, and chemical transport and retention processes
When did the US Soil Conservation Service begin assessing levels of erosion? Why is this significant?
1930s The assessment of erosion led to soil loss prediction equations for water and wind erosion If tolerable erosion levels are exceeded, the equations are used to ascertain what farming-system changes will reduce the erosion losses to acceptable levels
Pretty easy, overall.
Bridget Gonzalez is a new professor to UCLA. She has a background in Geomorphology and makes our Soil and Water Conservation class very entertaining and meaningful. Although the subject and textbook can get dry (pun intended), I recommend following her lectures and attending all lectures. Her tests cover what she mentions in class and are fairly easy. The tests are multiple choice questions mixed with short answer.
I learned more about the soil profile and how to conserve soil and water, keeping in mind of practices that prevent/slow down erosion.

Advice for students:
I advise you to memorize the main points of her lecture slides, which she posts each lecture
