The two main functions served by soil organic matter are: The chemical elements that are essential for the plant growth are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, sulphur, calcium, magnesium, iron, manganese, boron, zinc, molybdenum, nickel, copper, cobalt and chlorine. Most of the sprayed pesticide either washes off or degrades over time. Soil aggregates improve the structure of the soil and consequently its water retention. All organic matter derives from … The by-products produced in the course time also soil organic matter, though it is not as decomposable as the original plant and animal material. Soil organic matter (SOM) is a general term for several classes of carbon-containing compounds in the soil that originate from decomposed biota, including dead animals, microbiota (actinomycetes, bacteria, fungi), and plant matter. It is matter composed of organic compounds that have come from the remains of organisms such as plants and animals and their waste products in the environment. It is capable of decay, or is the product of decay; or is composed of organic compounds. Because of the nature of clay soil, it is not good for the cultivation of many types of crops. SOM is an important source of nutrients for plants. A soil’s ability to react with positively charged molecules is called it’s cation exchange capacity (CEC). Most of our productive agricultural soils have between 3 and 6% organic matter. There is not one definition of organic matter only. Organic matter enriches the soil. A pile plant and animal material such as leaves, manure and other organic wastes dumped into the soil is not called organic matter, but organic material. Vegetables, fruits, cereals all need to be grown, as well as crops to be used as feed for animals. And carbon in soil is an important part of the carbon cycle, which returns carbon to the atmosphere where it is used during photosynthesis. Organic matter includes plants and animals that are alive, dead, or in some stage of decomposition. Organic matter contributes to plant growth through its effect on the physical, chemical, and biological properties of the soil. Finally, rocks and fossils that store carbon, return it to the atmosphere during erosion, volcanic eruptions, or the cause of the increased amount of carbon in our atmosphere which is the main reason behind global warming, fossil fuel combustion.
