Soil types and properties

HOW SOIL IS FORMED?
It is formed by the process called withering. By forces of wind, rain, earthquakes and volcanic eruptions, big rocks will be formed into small particles. Thus soil is formed. Also the lichens growing on big rocks releases some chemicals that make the rock to dissolve and soil.

TYPES OF SOIL

Sandy soil
The soil particles are very big. It will have many pores in between the particles. The water holding capacity of sandy soil will be very poor. They can hold up much air.

Clayey soil
The soil particles are very small. They doesn’t have pore spaces. Very tightly packed. The water holding capacity is very high. They can't hold much air.

Loamy soil
The particles of soil are big. But the space among the particles is very less. Thus they can hold large amounts of water. this type of soil is very much appropriate for many of the plants to grow.
