describe three different soil chemical or physical properties that are affected by soil organic matter content. In full detail explain how each soil characteristic is affected.

Description as blow.

Explanation:

Soil is medium for plant growth and is an earth supporting layer called as pedosphere. Some physical and chemical properties of the soil are its mineral content, texture, exchange capacity, density, porosity, color, depth, fertility, and pH values. As soils hold about 50% solids i. e 45% mineral and 5% organic matter given sufficient time the soil profiles emerge and these consist more than 5 layers. Like A, B, C, D, E and H horizons. Soil texture includes article size such as sand, silt and clay and their interaction with organic matter such as water and gaseous biotic components give its terms of color, porosity and pH content to the soil. Its a commonly known fact that humus-rich soils are found at the top horizons and bedrocks at the bottom E horizons. Plant's roots go deep into the soils and hold these soils and don't let them wash away and thus enhancing the nutrient content in the soil again. Thus the organic content of the soil is balanced by a new matter that falls from above.
