A horizons are darker than B or C horizons because they contain more organic matter and are richer in nutrients. The organic matter in A horizons contributes to increased soil fertility, which supports higher plant growth. B and C horizons have less organic matter and are more mineral-rich, which makes them lighter in color.

Why does Horizan A often contains darker soil than Horizan B or C?

Horizon A may contain darker soil due to a higher organic matter content from accumulated plant material or decomposition products. This organic matter can contribute to the soil's color, as well as its fertility and structure. Horizons B and C may have lower organic matter content, resulting in lighter soil color.


How many soil horizons is there?

There are typically five soil horizons: O (organic), A (topsoil), E (eluviated), B (subsoil), and C (parent material). Each horizon has unique characteristics and plays a key role in soil composition and function.


What are the Five soil horizons?

The five soil horizons are O horizon (organic matter), A horizon (topsoil), E horizon (eluviated or leached layer), B horizon (subsoil), and C horizon (parent material). These horizons collectively make up the soil profile and influence soil characteristics and fertility.


What is the correct order of the different soil horizons?

The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.


What are 3 horizons of soil layers?

The three horizons of soil layers are the A horizon (topsoil), which is rich in organic matter and nutrients; the B horizon (subsoil), which contains minerals leached from the topsoil; and the C horizon (parent material), which is the weathered rock or sediment that the soil developed from.

What does the letters A B C stand for in the individual soil horizons?

A stands for top soil.B stands for who knows what and C stands for IDK


If a is less than b and b is less than c what is greater than c?

a < b < c So, neither a nor b is greater than c.


If a is bigger than b and b bigger than c which statement must be true?

if a is bigger than b and b is bigger than c a must be bigger than c... Transitivity


What the soil horizons?

horizon a= topsoil horizon b= subsoil i think horizon c im not sure of and then bedrock


A is less than b and b is less than c is a greater than c?

NO it is not because if a<b<c it could also be said without the b as a<c.
