PPT-Organic Matter Quality in Greenland Lakes

Dissolved organic matter DOM is an important property of lake ecosystems resulting from the decomposition of organic matter stored in soils and of plankton in the water column Colored dissolved organic matter CDOM the fraction that absorbs ultraviolet UV and visible light is the controlling factor for the optical properties of many surface waters Little is known about the mechanisms by which DOM and CDOM evolve in lakes formed during glacial retreat As part of a larger study of the ecosystems in glacial lakes the present project examined the quality of DOM and CDOM in lakes in SW Greenland Nine lakes in .

It is a dynamic material and is one of the major sources of nutrient elements for plants. . Objectives. Define: soil respiration and soil microbes. Explain the role of soil respiration in determining soil health. Diagram the role of soil respiration in the cycle of life on earth. List and explain inherent factors that affect soil respiration. Objectives. Define: soil organic matter. Explain the role of inherent factors affecting soil organic matter. Explain the five soil organic matter management practices.
