Yes, topsoil can degrade over time due to factors like erosion, compaction, nutrient depletion, and loss of organic matter. Regular maintenance and replenishment of nutrients can help maintain the quality of topsoil.
If it is stale and a very light brown and nothing grows on top of it, then you know you have bad soil.
Yes then you lose top soil for plants and crops don't grow as well.
Top soil is removed during construction to provide a stable foundation for the building. It helps prevent settling and shifting of the structure over time. Additionally, top soil contains organic matter that can decompose and cause uneven settling of the building.
Clay soil can be amended without tilling by adding organic matter such as compost, mulch, or manure on top of the soil. This helps improve soil structure, drainage, and fertility over time without disturbing the soil layers.
Soil erosion, leaching, and over-farming can cause nutrients in the topsoil to be removed. Erosion by water or wind can wash away topsoil along with the nutrients it contains. Leaching occurs when water moves nutrients downwards through the soil profile beyond the reach of plant roots. Over-farming without proper nutrient replenishment can deplete the soil of essential nutrients over time.
Bedrock is called the parent material of soil because it is the underlying layer from which soil is formed through weathering and erosion processes over time. The composition and properties of bedrock influence the characteristics of the soil that develops on top of it.
No, it is called permafrost, which is a top layer of frozen soil. It is bad for growing plants which is one reason that there is not many plants in the tundra.
When water runs onto soil, it can cause erosion by washing away the top layer of soil. This can lead to loss of nutrients, degradation of soil structure, and decreased soil fertility. Over time, it can result in land degradation and reduced agricultural productivity.
Top soil because it gives all other layers material and organics.
about 60 Cm 1-bad soil ~20 cm 2-for protect of freezing ~60 Cm
turning over soil implies just that, normally a spade is used, digging in a full spade depth; you then removed the soil and flip it over and back into the hole you just removed it from. Essentially bringing soil from below ground to the top and moving the soil from the top part down to the bottom of the hole. the process is repeated over a given area
Umm... let's see. The top layer is top-soil. The middle layer is sub-soil. The bottom layer is parent rock.... I think you've got the answer...... ;-) you're welcome!
