Humus can hold more water
in GENERAL a humus rich soil is better for plant growth, but it is dependant on the type of plant - e.g. plants that grow at the coast are at home in very sandy soils.
The biome characterized by soil rich in humus is primarily the temperate deciduous forest biome. This type of soil is dark, fertile, and nutrient-rich due to the decomposition of organic matter from the forest vegetation. Humus-rich soil is important for supporting diverse plant and animal life in this biome.
Podzol is a term given to soils that are infertile and have a light-brown color due to poor humus. Chernozem is a term given to soils that are rich in humus and thus are fertile. In addition, they have a black color because of the rich humus.
Alluvial soil is fertile and rich in nutrients due to its deposition by rivers and streams. It has good water retention properties, making it suitable for a variety of crops. Additionally, it is easy to till and manage for agricultural purposes.
The layer that contains the most humus and smaller rocks is the topsoil layer. Topsoil is the uppermost layer of soil that is rich in organic matter, such as humus, and contains smaller rock particles that have undergone weathering. It is the most fertile layer of soil and is crucial for plant growth.
Both humus and minerals contain nitrogen for growth of plants. Alluvial soils are rich in humus and minerals making them good for growth of plants.
The dark organic material that forms in soil as plant and animal matter decays is called humus. Humus is rich in nutrients and helps improve soil structure, moisture retention, and microbial activity, making it essential for healthy and fertile soil.

it kills plants:(
it is called loam and is very rich and very black
Desert soils contain a high percentage of sand and are low in organic material. This happens in areas where there are few plants that would provide the decayed leaves and other dead organic material called humus. Humus is rich in nutrients and is better able to hold water than sand.
