When rolled between the fingers, sandy soil feels gritty, and when you try to mold it into a ball or sausage shape, it falls apart. It is also generally pale in color. The benefits of sandy soils are that they are light and well drained, and easy to work. Mediterranean plants are happiest in sandy soil, because they never suffer from soggy roots. However, their poor water-holding capacity makes sandy soils prone to drought and lacking nutrients because nutrients are dissolved in water.
