<h3>What is Soil Layers ? </h3>
According to their physical, chemical, and biological properties, distinct layers of soil can be arranged parallel to one another to form soil layers. The soil horizon is the term for it.
In terms of outward appearance, layer 1 of the soil is the oldest while layer 7 is the youngest. On the basis of whether one soil layer has accumulated on top of another, it can be estimated.
