And, they can even refine nitrogen from the air into a useful form for plants! The "very dead" or humus is the long-term SOM fraction that is thousands of years old and is resistant to decomposition. I like to think about these millions of microbes under our feet as workers at recycling plants, mining operations, and refineries. doi: Simon C, Daniel R (2011) Metagenomic analyses: past and future trends.

Soil organic matter (SOM) helps to sustain the soil health as well as its quality, inactivate toxic compounds, suppress pathogens, and protect environmental sustainability. Collectively, soil microorganisms play an essential role in decomposing organic matter, cycling nutrients and fertilising the soil.

What happened to Alaska’s soils during the 2019 fires? Peanuts, alfalfa, clover, beans, and lentils, are all legumes. Nutrient recycling in soil is generally performed by microorganisms. The efficient soil microbes play an important role, since they are responsible to drive various biological transformations and different pools of carbon (C) and macro- and micronutrients, which facilitate the subsequent establishment of soil-plant-microbe interaction. Hi Kathryn, this question is beyond the scope of Soils Matter – which is to provide evidence-based soils information to the general public. J Clean Prod 102:562–563. Toward the global knowledge of soil microbial dynamics, its function is increasing rapidly, but the knowledge of rhizospheric complex is limited, despite of their importance in regulating soil-plant systems. They connect with plant roots to provide access to the freshly-released nutrients. Yadav BK, Sidhu AS (2016) Dynamics of potassium and their bioavailability for plant nutrition. How are soil microbes affected by fertilizer in soils? They all have specific jobs helping make nutrients available for plants. All of these minerals are needed for healthy plants and good crop yields. The soil microorganisms that fill the “miner” role work on nearby rocks and minerals, not organic matter like the recyclers.

Why do the Loess Hills of Iowa need to be farmed in terraces? 88.208.193.166. Springer, India, pp 61–75. The final type of microbes are the “refiners.” Refiner microbes, a class of bacteria called Rhizobia, are able to take nitrogen from the air and process it into a form usable by the plant. Cover crop residue, compost, or mulch are good sources of organic matter. The microorganisms are key players to man… Without the cycling of elements, the continuation of life on Earth would be impossible, since essential nutrients would rapidly be taken up by organisms and locked in a form that cannot be used by others.
