Provide most of the organic matter that gets broken down to form humus.
plants and humus
In three layers/horizons: A (made of topsoil, crumbly, dark brown soil mixture of humus, clay, and other minerals.) B (made of subsoil, made of clay and other particles with little humus.) and C (contains partly weathered rock.)
Organic matter transformates into humus. For more information on this process, check this link: http://en.wikipedia.org/wiki/Humus
Topsoil is made of humus and mineral particles weathered from the soil's parent material.

Black soil has the maximum content and is extremely fertile.
HUMUS IS A DARK-COLORED,MINERAL SUBSTANCE THAT DEVELOPS AS DEAD PLANTS AND ANIMALS.loam is soil with a crumbly texture that is made of equal parts of clay,sand,and silt.

Topsoil typically has the largest particle size among humus, subsoil, and topsoil. This layer is the uppermost layer of soil and is composed of a mix of organic matter, minerals, and nutrients. Humus is a component found within topsoil that is made up of fully decomposed organic matter, while subsoil is found beneath the topsoil and can have a finer texture due to lower organic content.
The six properties of soil are texture (particle size), structure (arrangement of soil particles), moisture content, pH level, organic matter content, and nutrient availability. These properties are important for understanding soil quality and its ability to support plant growth.
Humus is generally considered to be light in terms of its texture and structure. It is a dark, organic material formed from the decomposition of plant and animal matter, which contributes to its airy, crumbly consistency. This lightness helps improve soil aeration and drainage, making it beneficial for plant growth. However, its weight can vary depending on moisture content and the specific composition of the soil it is in.
Humus content of the soil. What think the heat scientists about black surfaces and heat absorption? Black surfaces absorb heat faster and contain it longer. Mostly, humus is black or dark in color. Soil with much of the humus content tends to absorb more heat and gets heated faster than soil c9ontaining less humus.
one major difference between humus and clay soil is that humus is made up of remains of dead plants and animals and it is topmost layer of the soil whereas clay soil is a type of soil which is used to make earthen pots or clayey toys etc.
puree chickpeas & sesame paste into a thick texture. Add it to your mold & set it in the fridge to chill.
Anywhere from "none" to "lots and lots". Calcareous soil is soil high in calcium (lime) content. it has nothing to do with the percentage of humus, which is decayed organic material.
