Define Clayey Humus Loamy Precolation Moisture …

Humus: The decaying dead matters in soil are called humus. Humus makes the soil fertile and provides nutrients to the plants.
 

Clayey Sol: Particles of clayey soil are very small in size. This makes the particles of clayey soil packed tightly. There is very little space among the particles. Water does not drain quickly through clayey soil because of less space among particles. So, clayey soil is not well aerated and retains more water.

Clayey soil is used in making of toys. Clayey soil is good for growing paddy.

Loamy Soil: Particles of loamy soil are smaller than sand and larger than clay. Loamy soil is the mixture of sandy soil, clayey soil and silt. Silt is the deposit in river beds.

Percolation Rate of Water: Amount of water drained through water in unit time is known as percolation rate of water in soil.

Moisture present in soil: Amount of water present in soil is called moisture present in soil. The amount of moisture present in clayey soil is highest and that in sandy soil is lowest.

Sandy soil: Sandy soil is not fit for any crop as it does not retain water. However, some thorns and bushes do grow on sandy soil. Millets can be grown on sandy soil.
