Microorganisms are responsible for the degradation of organic matter, which controls the release of plant nutrients, but is also important for the maintenance of soil structure and sustainability of soil quality for plant growth. Soil microbial metabolism boosts plant nutrition by converting recalcitrant forms of N, P, and S to forms that are more bioavailable for plant uptake. Beneficial soil microbes perform fundamental functions such as nutrient cycling, breaking down crop residues, and stimulating plant growth. They supply nutrients by driving biological inter-conversion of nitrogen, sulfur, and phosphorous. They help in maintaining atmospheric carbon through respiration and methanogenesis. The soil microorganism is also involved in symbiotic relationships. These organisms have many tasks, and are central to crop fertility, purifying the environment from pollutants, regulating carbon storage stocks and production/consumption of many significant green house gases, such as methane and nitrous oxides. In fact, they help you digest food, protect against infection and even maintain your reproductive health. We tend to focus on destroying bad microbes. But taking care of good ones may be even more important. Microorganisms play a crucial role in nutrient cycling in soil. The composition and activity of micro biota 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. The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition. Soil plays a crucial role in nature's cycles, including the nutrient cycle, which involves how much soil organic matter i.e. carbon, nitrogen and phosphorus is taken up and stored in soil. In the process, nutrients get absorbed, transferred, released and reabsorbed. It is a natural recycling system of mineral nutrients. Nutrients consumed by plants and animals are returned to the environment after death and decomposition and the cycle continues. Soil microbes play an important role in nutrient recycling. Soil microorganisms are responsible for biomass decomposition, biogenic element circulation, which makes nutrients available to plants, biodegradation of impurities, and maintenance of soil structure. Soil microbes play a vital role in the sustained growth of plants. They decompose and recycling nutrients bound in organic materials. They help access minerals in rocks large and small and, they can even refine nitrogen from the air into a useful form for plants. Both plants and microorganisms obtain their nutrients from soil and change soil properties by organic litter deposition and metabolic activities, respectively. Microorganisms have a range of direct effects on plants through, e.g., manipulation of hormone signaling and protection against pathogens. Microorganisms require certain basic nutrients for growth and maintenance of metabolic functions. The amount and type of nutrients required range widely depending on the microorganism. Microorganisms can derive energy from carbohydrates, alcohols, and amino acids.
