Soil heavy with clay does not have a lot of air in it, as it is very dense. As a result, drainage of water is bad, and it can be hard to grow fragile plants.
My garden has London Clay in it - it is very thick and does not drain well at all, especially if it has rained recently. It is also a peculiar shade of yellow (lol)
Loam is considered to be the best kind of soil because it has enough air and water space for the roots of the plant to get air and water for the good growth of the plant.
Yes, air is present in soil. Since soil is made of particles ranging from sand ( 0.175mm to 1.5mm), silt (0.02mm), clay ( 0.0015mm), there are minute pores between these particles for air to reside. That is why aeration of the soil is really important to plant survival.
Soil typically doesn't float in water; instead, it tends to sink. The buoyancy of an object in water is influenced by its density. If soil particles are denser than water, they will sink. However, if there are pockets of air or organic matter in the soil, they might trap enough air to make the soil appear buoyant temporarily.
yes soil contains air because it is also present in the earth
The best type of soil for agricultural purposes is loam. Loam soil has rock particles of many different sizes. This results in many pockets that can hold air or water, which keeps the soil loose enough that plants can grow into it easily.
sand soil
I think air help soil because air can broke down and then the rock goes inside the soil
Burrowing mammals improve soil by aerating, or mixing air into, the soil.
nitrogen cycle
nitrogen cycle.
If there is no air in the soil, the organic matter in the soil will begin to rot. It is called anerobic decomposition. Air in the soil allows for drainage, gives roots a place to grow, and keeps methane from building up by allowing it a ready escape.
If the soil is hot heat rises and the air near and around the soil will rise to affect the other particiles of air.
