Answer the following question to best of your ability IEปCallaneEarth SUPPLEMENTAL EXERCISES - ESCI 103L - Cuyahoga Community College9. The nutrients contained in soil organic matter are important for plant growth, but also affectcarbon levels in the atmosphere.a. How is soil carbon increased?b. How does soil act to decrease carbon levels in the atmosphere?GlossaryActive organic matter.-Organic compounds used as food by micro-organisms and associated withhigh biological activity. Active soil organic matter breaks down faster than other components of soilorganic matter and responds more quickly to changes in management.Fresh residue.-Plant residue, dead animals, and other organic substances that have recently beenadded to the soil and exhibit minimal decay.Humus (stable organic matter).-Complex organic compounds that remain after organisms haveused and transformed the original organic material. Humus is not readily decomposed either becauseit is physically protected inside soil aggregates or it is chemically too complex to be used by mostorganisms. Humus is important in binding soil aggregates and improves the water and nutrient-holding capacity of soils.Mineralization.-Organic matter decomposition that releases nutrients in a form available for plants(e.g., phosphorus, nitrogen, and sulfur).Soil micro-organisms (small living organisms).-Bacteria, fungi, nematodes, protozoa, andarthropods, etc.Soil organic matter (SOM)-Organic component of soil, consisting of plant residue (fresh), livingorganisms, decomposing organic matter (active), and stable organic matter (humus).USDA is an equal opportunity provider and employer.SOIL QUALITY INDICATORS - RESPIRATION PORTIONGlossaryAmmonification-Production of ammonium (NH4) from the decomposition of SOM.Denitrification.-Anaerobic conversion and loss of nitrate nitrogen to nitrite and NO, N₂O, and N₂gases.Mineralization.-Decomposition of organic matter that releases nutrients in a form available for plantuse (e.g., phosphorus, nitrogen, and sulfur); occurs as a result of respiration.1824 25 28 Sun Alt Enorm 1 and 2 Sun Switch
