4 soil formation processes tested?
I was wondering if the 4 soil formation processes will be tested? It wasn't covered during lecture but its in the soilweb200. Below are the 4 processes
1) Additions - the addition of organic material (i.e., addition of dead root mass in grassland ecosystems). 2) Transfers - the downward movement of soluble material in water (i.e., redistribution of calcium carbonate in a soil profile). Note that while the distribution of material with depth has changed, the material has not been completely lost from the soil. 3) Transformations - the weathering of primary minerals to secondary minerals, or the decomposition of organic matter. 4) Removals - the complete loss of material from the soil profile (i.e., the loss of calcium carbonate in a soil forming in a humid environment).
Celeste, these concepts will be included later in the course. For now, focus on the 5 factors of soil formation presented in lecture #3
