What is "well aerated"?
Answers
Answer:
In a well-aerated soil, the O2 content is high with a large percentage of the soil pore spaces filled with air. However, when soil pore spaces are filled with water, anoxia exists.
Answer:
Size of particles of soil is very important for the properties of soil. So, soils are categorized mainly in three types based on the proportion of size of particles. These are Sandy soil, Clayey soil and Loamy osil.
Sandy soil: Particles of sandy soil are larger in size. Because of larger in size, sand particles cannot fit close together and hence there is enough space among them. These spaces are filled with air. Water drains quickly through sandy soil. So, sandy soil is called well aerated, light and dry.
Sandy soil is not fit for vegetation as it does not retain water. However, millets can be grown on sandy soil.
Clayey soil: 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.
