متن کاملBiological Formation of Organic Substances from Particulate Organic Matter
Biological degradation of terrestrially derived macromolecules including lignin and cellulose has been shown to produce a large number of environmentally relevant phenolic compounds. It has demonstrated that extracellular superoxide (O2 ) is produced by heterotrophic bacteria that are common in lakes, soil, hydrothermal vents, marine sediments, estuaries and oceans. Rates of superoxide producti...
متن کاملEffects of augmentation of coarse particulate organic matter on metabolism and nutrient retention in hyporheic sediments
1. Metabolic and biogeochemical processes in hyporheic zones may depend on inputs of coarse particulate organic matter. Our research focused on how differing quantity and quality of organic matter affects metabolism and nutrient retention in the hyporheic zone of a first-order Appalachian stream. 2. Sixteen plots were established on a tributary of Hugh White Creek, NC, U.S.A. Sediment was extra...
متن کاملEffects of forest disturbance on particulate organic matter budgets of small streams
Organic matter dynamics were studied in five streams at Coweeta Hydrologic Laboratory. Three of these streams drained logged watersheds, and two drained reference deciduous forest watersheds. Litter inputs to the streams draining disturbed watersheds were significantly lower than to reference streams. Additionally, while undisturbed litterfall consisted primarily of relatively refractory leaf s...
متن کاملDing Et Al.: Tillage Management Affecting Soil Organic Matter
ganic C (SOC). Soils of the southeastern United States of America, particularly sandy Coastal Plain soils, have Soil organic matter (SOM) is of primary importance for maintaining inherently low SOC contents (typically below 1%, Hunt soil productivity, and agricultural management practices may signifiet al., 1982). Consequently, small changes in the SOM cantly influence SOM chemical properties. ...
