Growing rose requires a soil rich in organic matter. A humus-rich soil would be ideal for this purpose.
It is rich in nutrients and acts like a fertilizer.
All soil contains some humus. If it doesn't it is not soil.
Truly good soil is made up of the following: A proper balance of clay, sand and silt, with a goodly addition of humus (decomposed organic matter). If it has those things, it will automatically have the minerals and tiny microorganisms. Such soil is called "rich loam", and is an ideal growing medium for most things.
Humus can hold more water
a rich soil that is good is the soil in the ground above the Earth's axis
Loamy soil is rich in humus and nutrients, making it ideal for plant growth. It consists of a well-balanced mixture of sand, silt, and clay, providing good drainage and water retention.
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.
it kills plants:(
fertility
Soil that contains humus is known as humus soil. Humus is a dark, organic material that forms when plant and animal matter decomposes. Humus soil is rich in nutrients and helps improve soil structure, drainage, and fertility. It is important for healthy plant growth and biodiversity in the soil.
you are likely to find dark, humus-rich soil in an A-horizon profile because that's where dark soil is found & the composition is the particles of weathered rock materials mixed with humus.
