Question 2: Why there is a need for granules? Explain the compaction of granules in dry pressing. What would the fill density in the die cavity be, if granules fill the die cavity with random close packing. Assume that particle packing density of 50% within the granule.

Your soil is 3.3% organic matter and 18.8% clay. Of that 18.8% clay, 20% is kaolinite, 20% is vermiculite, 40% is smectite, and 20% is mica. It is 1.7% iron oxide. Your soil is at a pH of 7.    What is the total CEC of this soil in cmolc/kg? Please answer to one decimal.

When the water table is deep (like 30 to 100 feet deep) and the surface soil is at field capacity, the soil water potential at field capacity for loamy soils will be about: -31 bar ) -1,000 bar O -15 bar -0.01 bar O -1/3 bar
