Soil is a combination of minerals, broken rocks, decaying organic matter or humus and living organisms.
Soil also has water and air in it.
Humus is soft and dark and is nutrient-rich.
Soil gets formed due to many natural reasons like wind, water, sun and living organisms.
The factors that decide the structure of soil are the median size of particles that are in it and the quantity of microscopic organisms and humus in it.
The quantity of humus, nutrient content and the soil depth are some factors that can decide the kind of plants that can thrive in it.
