SOIL DEGRADATION: EFFECT ON THE ENRICHMENT RATE
Keywords:
soil composition, particulate matter, semiarid, wind erosionAbstract
The enrichment ratio (ER) is used to evaluate the relative loss of parameters such as clay, silt and organic C in water or wind eroded materials. As the soil degrades, their concentrations in the eroded material would increase, increasing ER. This was evaluated by analyzing concentrations of different parameters in three different textured soils, sampled at three different times, and in their particulate matter (PM). Contrary to expectations, the concentrations of the parameters remained relatively constant in PM, but ER increased. This was due to decreases in the concentrations in the soils and not to increases in PM.
