The Influence of Nutrients on the Coastal Wetlands of the Mississippi Delta

摘要: Among the solutions being proposed for reversing wetland loss in Mississippi River Delta are creation of diversions to reintroduce suspended sediment carried river. In areas rapid relative sea-level rise, as Delta, it is generally accepted that a supply flood water and mineral sedimentation critical sustaining wetlands. But plans create have raised questions about collateral effects nutrients River, may contravene benefits sediment. This review finds balance empirical theoretical evidence supports benefit above- belowground plant production fresh can be effective beneficial restoring wetlands especially if designed maximize inputs. The input sediment, nutrients, will change community composition some their biogeochemical processes. Most nitrogen should assimilated or denitrified. Labile organic matter likely degrade more quickly, but labile does not add ‘new’ soil volume its speed decay little consequence. Additional research needed before we fully understand consequences on preservation building what known activities lignin-degrading fungi enzymes, refractory increase contribute positively accretion.
