Residual soils are directly derived from the parent rock through weathering, without being transported. As a result, the soil particles are not sorted as sedimentary soil deposits, and they tend to be heterogeneous. They also tend not to exhibit any direct relationship between void ratio and stress because the voids arise from the rock being chemically

Aug 24, 2012· Soil Properties and Application Rates. The pH level of the soil was basic (higher pH) and changed with depth slightly. EC values of the soil at 25 °C decreased with depth as the clay content decreased (Table 1 ). These considerable changes in soil properties with depth made this soil an interesting study area.
