Clay are soil particles consisting of mineral particles less than 0.002 mm in diameter. Many of the properties of soil depend on the type and quantity of clay particles in the soil. Cultivation is the mechanical preparation of the soil required for the growing of crops or pasture. Dispersible Soil is structurally unstable. Highly dispersible soils are extremely erodable and are associated with high exchangeable sodium and low soluble salt concentrations.
Artificial flocculation is required to help the settling process.
Soil dispersability can be determined by laboratory tests. Earth Bank and Channel a bank is a ridge or embankment of compacted earth. A channel is an excavated earth drainage ditch or path used to intercept and direct runoff to a desired location. Erosion is a natural process. Rain or wind detaches a soil particle and provides energy to move the particle.
