Question

differences between Sandy, clayey and loamy soil, based on the following properties – Composition, Size of particles, Air spaces, Porosity, Water absorption capacity and water percolation tendency.

Answer 1

Answer:

Soil is one of the most important natural resources.

Explanation:

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 loamy. Thus, the soil can be classified as sandy, clayey and loamy.

The sizes of the particles in a soil have a very important influence on its properties. Sand particles are quite large. They cannot fit closely together, so there are large spaces between them. These spaces are filled with air. We say that the sand is well aerated. Water can drain quickly through the spaces between the sand particles. So, sandy soils tend to be light, well aerated and rather 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.

Answer 2

Answer:

Here so s your Answer :

Hope it helps you

Explanation:

Sandy soil :

1. Soil particles are bigger in size
2. The large spaces between them are filled with air
3. soil cannont retain water as water can dran out quickly through the spaces between the cell particles.

Clayey soil :

1. It has higher proportion of fine and smooth soil particles
2. There is very little space between the soil particles
3. it cannot return to air

Loamy soil:

1. Mixture of sand and silt and clay particles
2. It can hold both air and water
3. Best soil for growing most of the crops
