Do bacteria recycle organic matter and role of microorganisms in plant nutrition and soil health?
@ RK, yes, bacteria can recycle soil organic matter through various processes that help to release different inorganic molecules which may consumed by plants and microorganisms to perform their function. Actually microorganisms play the main role in soil nutrient cycling. Their overall impact help to maintain the soil health , quality status and plant nutrient management. For nutrient mobility and absorption microbes play the essential role. They may also play the role to reduce diseases and stimulate plant growth.
Soil bacteria perform recycling of soil organic matter through different processes, and as a result they produce and release into the soil inorganic molecules (PO 4 3 −, CO2) that can be consumed by plants and microorganisms to grow and perform their functions. Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don't just eat nature's waste, they recycle it. The process of decomposition releases chemicals that can be used to build new plants and animals. Microorganisms play a crucial role in nutrient cycling in soil. The composition and activity of microbiota impact the soil quality status, health, and nutrient enrichment. Microbes are essential for nutrient mobility and absorption. Through their varied functions, they stimulate plant growth and reduce diseases. Soil microorganisms are responsible for most of the nutrient release from organic matter. When microorganisms decompose organic matter, they use the carbon and nutrients in the organic matter for their own growth. Microbes create nutrient-like carbon, nitrogen, oxygen, hydrogen, phosphorus, potassium, trace elements, vitamins and amino acids and make them available for plant in right form for their growth and health. Bacteria and fungi are the major decomposer on earth and crucial component for composting and humus formation. Within food plant cropping systems, microorganisms provide vital functions and ecosystem services, such as biological pest and disease control, promotion of plant growth and crop quality, and biodegradation of organic matter and pollutants. Mats of filamentous bacteria absorb the soluble nutrients from the sewage and protozoa mix through the slurry, stirring up the bacteria to keep them feeding. Through this process, bacteria can remove up to 90 percent of the organic matter from the wastewater.
