Humus
Soil is composed of organic and inorganic parts. Inorganic is weathered rock. Organic is dead or decaying organisms called humus. Fallen leaves are part of what makes up humus. Fallen leaves (as well as all humus) are found in the "O" horizon as well as the "A" horizon.
Soil is made up of a thin layer of weathered rock, humus, air, and water.
The mixture of minerals, humus, air, and water that makes up part of the Earth's crust is called soil. Soil plays a crucial role in supporting plant life and maintaining ecosystems. It is a dynamic and complex environment that varies in composition depending on its location and environmental conditions.
"Humus is in soil," "the humus levels were high," Did I answer your Question?
Humus provides essential nutrients to the soil, improves its structure by increasing water retention and aeration, and promotes beneficial microorganism activity. It also helps create a healthy environment for plant roots to grow and develop properly.
I like to eat humus. I dip my carrots into humus.
No, Humus is made from dead organic plants and animals.
That it makes the nutrients within humus soluble is a reason why water is important to humus. Humus is dark brown, fresh smelling, nutrient rich organic matter. So it's a source of necessary nutrients to plant roots, soil, and soil food web critters. But the nutrients must be in soluble form in order to be available. Otherwise, they're present in soil but unavailable and inaccessible.
