Say that again...What gives our soils so much Diversity?
ClimateFor instance humid and moist conditions promote thicker deeper soils
Relief or TopographyThe topography can direct the water and sediments that change soil characteristics
TimeSome time it takes alot... sometimes not so much!

OrganismsMany type of soil organisms move soil nutrients and support soil quality
parent MaterialThe upper portions of the soil horizon is made form the Parent materil

Level 3 Elaborate: Measuring CO2 levels in soil measures nutrient level
After you have completed the lab assignment for this unit convert all the data you have collected into an excel or google slide document and make a line or bar graph and then export to a Word or Google Doc document. Explain what the graphs tell us about the soil health and nutrient levels. In addition, why did we use the CO2 ppm as a measure of soil health?
