Sandy soil feels gritty and grains, which consist of granite, limestone, quartz and shale, it is unlikely that size. If these particles are probably the largest are called gravel. It flows easily, and many of the nutrients through the filter of water. If enough organic matter is added, it is easy to grow. It is a tendency to over-drain and dry in summer and wet it is difficult to retain moisture and nutrients.
Silty soil has particles that are smaller than sand and larger than clay. If you rub between your fingers, it feels good. Drains more slowly than sand, but poor to hold together. It is made of high quality agricultural land, but erodes very easily and just high winds and even a dust storm. It is also the land that lies at the bottom of a river.
