Detailed explanation-1: -Most sand grains consist of quartz, but they can be of any mineral composition. Sand is also the textural class name of any soil that contains 85 percent or more sand and no more than 10 percent clay.

Detailed explanation-2: -Sandy Soil: Advantages and Disadvantages. Sandy soils are light and gritty to the touch. Because sandy soils have large particles, they dry out quickly, are often low in nutrients and acidic. Both water and fertilizer have a tendency to leach out of the soil-escaping to waterways before the plant can utilize them.

Detailed explanation-3: -Any particle falling within this range of sizes is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm by the latter system, and from 4.75 mm up to 75 mm in the former) and silt (particles smaller than 0.0625 mm down to 0.004 mm).

Detailed explanation-4: -Sandy soil has the largest particles among the different soil types. It is dry and gritty to the touch. The particles have huge spaces between them and so it can’t hold on to water.
