1. Determine the textural class for each foot of soil depth from the following data. 2. Bulk density (Db) samples were collected from both fields and all depths with a sampler whose measured volume was 300cm3. Samples were oven dried at 10 C for 48 hours, removed, and the soil dry weight (in g) determined. The follo data were obtained. Calculate Db (in g/cm3 ) for each of the 12 samples
