Desert
pavement is created as a result of deflation. Desert
pavement is formed by the process of deflation. Normally, small and fine
fragments are carried by wind since they are light in weight as the larger
compact particles are left behind. What remains is rocky, compact, and not
easily eroded, and it is what is commonly referred to as the desert pavement.
It is done so that the soil of farms is not used for only one set of nutrients. It helps in reducing soil erosion and increases soil fertility and crop yield.
