Question

why topsoil is important ​

Answer 1

Answer:

Topsoil is the primary resource for plants to grow and crops to thrive and the main two parameters for this are carbon and nitrogen. The nitrogen provides energy and carbon is a tissue builder and plants require them in a range of ratios to enable suitable growth.

There is generally a high concentration of roots in this layer as plants obtain much of their vital nutrients here. Accurate depth of the topsoil layer is measured as the depth of the surface to the first densely packed soil layer known as subsoil.

Answer 2

• Carbon and nitrogen are the two most important elements for plants to develop and crops to thrive in topsoil.
• Plants require a range of ratios to permit proper development, with nitrogen providing energy and carbon providing tissue building.
• Here layer usually has a lot of roots since this is where plants get a lot of their nutrition.
• The depth of the topsoil layer is accurately determined as the distance from the surface to the first tightly packed soil layer, which is known as subsoil.
