differentiate between topsoil and subsoil
Answers
Answer:
Topsoil is slightly different from subsoil, where it is found on the very top of the surface and is prepared from erosion of bedrock. Topsoil tends to be much darker in color since the soil is more fertile than subsoil. This is because the soil is rich in organic matter.
Answer:
Explanation:
Subsoil is the layer of soil below the topsoil. It contains mainly sandy and clay deposits without a lot of organic matter. Although subsoil is much less fertile than topsoil, it can be amended to increase its plant-growing capacities. Subsoil is also much lighter in color and much harder to handle than topsoil. It is, however, much looser than the hardened layer of bedrock lying beneath it. One advantage that subsoil has over topsoil is that it contains few if any weed seeds because of its depth, therefore increasing its attractiveness to growers and companies that make topsoil.
Topsoil is more life supporting for living insects, since the soil is directly exposed to the atmosphere and allows for greater exposure due to its small, loose particles. This allows earthworms, centipedes, millipedes and other insects to make a home in the topsoil. As a result, the topsoil becomes more open to nutrients and water because of the holes that is made by these insects. This allows gas to be present, which plays a fundamental role for living insects.
