write the short note about the desert soil??
Answers
Explanation:
Desert soil is mostly sandy soil (90–95%) found in low-rainfall regions. It has a low content of nitrogen and organic matter with very high calcium carbonate and phosphate, thus making it infertile. ... This soil is susceptible to wind erosion and supports a low density of population.Since desert soils are dry, and support little vegetation, can desert soils be used for agriculture? Some desert soils support shrubs that goats and sheep enjoy for browse (eating). Desert soils may support some grasses, especially after a rain that animals can graze. Some desert soils are used by ranchers.
Answer:
DESERT SOILS
Desert soils are dry, and tend to have clumpy vegetation.
Desert soils form in areas where the demand for water by the atmosphere (evaporation) and plants (transpiration) is much greater than precipitation. Deserts cover 20 to 33% of the Earth’s land surface, and can be found in the tropics, at the poles, and in between.

Penguins live in deserts too! As Antarctica is one of the driest places on the planet.
Deserts are defined as being very dry. Not all of them are hot, or sandy. The antarctic continent is a dry, polar desert. At the south pole, it doesn't snow very often, though, blowing snow can accumulate up to 20 cm. Even though moisture levels are really low, deserts are prone to flash flooding when they recieve rain. This is what causes all of the interesting and colorful rock formations. The lack of soil moisture keeps minerals from leaching out of the soils, and can even create cement like horizons near the soil surface.
entisol
Dunes are sands blown into piles.
Most desert soils are called Aridisols (dry soil). However, in really dry regions of the Sahara and Australian outback, the soil orders are called Entisols. Entisols are new soils, like sand dunes, which are too dry for any major soil horizon development. They also occur in floodplains after a spring flood, which is why they can occur in the desert.
