Soil Types 
? The soil is classified on the basis of the 
proportion of particles of various sizes.
? If soil contains greater proportion of big 
particles it is called sandy soil.
? If the proportion of fine particles is relatively 
higher, then it is called clayey soil.
? If the amount of large and fine particles is 
about the same, then the soil is called

? Water can drain quickly through the spaces between the 
sand particles. So, sandy soils tend to be light, well aerated 
and dry.
? Clay particles, being much smaller, pack tightly together, 
leaving little space for air. Unlike sandy soil, water can be 
held in the tiny gaps between the particles of clay. So clay 
soils have little air. But they are heavy as they hold more 
water than the sandy soils.
? The best topsoil for growing plants is Loamy soil is a 
mixture of sand, clay and another type of soil particle 
known as silt. Silt occurs as a deposit in river beds. The size 
of the silt particles is between those of sand and clay. The 
loamy soil also has humus in it. It has the right water 
holding capacity for the growth of plants.
