Water is vital for the life and survival of all plants. The term 'organic matter' is used for both organic matter in the soil (better called soil organic matter), and the many manures, composts (garden and green waste) and other organic materials added to the soil to increase the organic matter content. Many people assume that all farming is intrinsically organic by its very nature — but modern agriculture looks a great deal different than the pastoral pictures we see in our collective unconscious. Crop and plant residue, tree litter, livestock manure (Figure 1), animals and different types of soil organisms, their by-products and to a lesser extent human waste contribute to form organic matter. Soil contains the air, water and food that provides a suitable place for plants to grow. Soil is one of our most important tools in the fight against climate change – there are 2,500 billion tonnes of carbon stored in the world’s soils! Most garden and landscape plants benefit from increases in soil organic matter. That’s more than in the plants, trees and the atmosphere combined. These tiny life forms are responsible for the physical and chemical reactions that break matter into its base components. CEC is produced during the decomposition process, increasing the soil’s ability to retain calcium, potassium, magnesium, and ammonium. Organic matter (or organic material) is matter that has come from a recently living organism. Fresh pasture has high water content and will have a lower percentage of dry matter than an equivalent weight of dryer feed, such as hay or grain. The higher the organic matter the better the soil is. It provides step-by-step information on soil-improving practices as well as in-depth background—from what soil is to the importance of organic matter. The activities of these soil organisms are very important for the soil and the proper growth of the plants. The stable fraction (humus), stores carbon and reduces loss of organic carbon to decomposition. This is why many agriculturalists say that organic matter is one of the most important sources of nutrients for plants. By the time seed is harvested, very little of the pesticide remains, but there can be residual amounts of systemic pesticide in the seed. Prevention of soil erosion: It was found that an increase in soil organic matter from 1 to 3 % would result in lessening erosion up to 20-33%. We all know that sandy soils are not the best when it comes to the cultivation of crops because of the fact that this type of soil cannot hold water for long. 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. And carbon in soil is an important part of the carbon cycle, which returns carbon to the atmosphere where it is used during photosynthesis. What is organic matter ? Soil Organic Matter Agronomy Fact Sheet Series Department of Crop and Soil Sciences 1 College of Agriculture and Life Sciences Soil organic matter is the fraction of the soil that consists of plant or animal tissue in various stages of breakdown (decomposition). All organic matter derives from … Most of our productive agricultural soils have between 3 and 6% organic matter. What happens to these chemicals – organic and non-organic? Organic material is unstable whereas organic matter is stable in the soil. K is generally playing an important role for the quality of harvested plant products.
