| 11. | Note that one source of groundwater organic matter is soil organic matter and sedimentary organic matter.
|
| 12. | This increases the amount of soil organic matter.
|
| 13. | When the mulch breaks down, soil organic matter is built up and additional nutrients for crops become available.
|
| 14. | No-till farming has carbon sequestration potential through storage of soil organic matter in the soil of crop fields.
|
| 15. | Introduction of moisture exposes soil organic matter to enzyme catalysis and also increases loss of soluble monomers via diffusion.
|
| 16. | Although leguminous cover crops have large biomass production and turnover, they are not likely to increase soil organic matter.
|
| 17. | By contrast, tree leaves falling on the forest floor are the principal source of soil organic matter in the forest.
|
| 18. | Forest fires release absorbed carbon back into the atmosphere, as does deforestation due to rapidly increased oxidation of soil organic matter.
|
| 19. | Soil micro fauna, such as bacteria and fungi, break down soil organic matter and help maintain soil quality while recycling nutrients.
|
| 20. | Effects of this increase on forest soil temperature include reduced tree growth and higher decomposition rates of deep soil organic matter.
