To which soil groups do these four soils possibly belong?
A soil sample has the following size distribution;
4 to 2mm = 17%,
2 to 0.05 mm = 12%,
0.5 to 0.005 mm = 22%
0.005 to 0.002 mm = 10%
<0.002 mm = 39%
what are the percentages of clay, silt, and sand? Using USDA calssification what is the modifier and tetural classification
Enumerate the different classifications/categories of the saturated formation of earth materials which are of great importance in the aspect of groundwater utilization. Give a little description of each of them and cite one or more characteristic/s which differentiate them from each other
