mangrove soil quality

Veröffentlicht von am

The decline in mangrove coastlines over the years has raised the need to investigate and document the soil quality of microsites within regenerating and established mangrove stands. The decline in mangrove coastlines over the years has raised the need to investigate and document the soil quality of microsites within regenerating and established mangrove stands. However, mangroves are disappearing worldwide because of demographic increases. The objectives of the present study were to quantify the evolution of soil quality, carbon stocks and carbon fluxes after mangrove clearing. Sci Total Environ. It is estimated that mangroves store 3 to 4 times more carbon than tropical forests. Various soil physicochemical, microbial and enzymatic properties were analyzed. Hereafter, the mangrove substrate will be referred to as soil because it meets the criteria used by the Soil Survey Staff . Due to the rapid decrease in the soil carbon content, CO2 fluxes at sediment interface were >50% lower in the cleared zone. Mangrove forests play an important role in biogeochemical cycles of metals, nutrients, and C in coastal ecosystems. Degradation and destruction of mangrove forests in many regions have resulted in the alteration of carbon cycling. The soil of the mangrove forest acts as a reservoir of carbon that is in interaction with the atmosphere, storing about three times the biomass that makes up the vegetation and structure of mangroves (Sa et al., 2001).  |  On the basis of exchangeable sodium percentage and electrical conductivity the mangrove soils were classified as saline sodic and the non-mangrove soil non-saline sodic. Zhu R, Zheng Z, Li T, Zhang X, He S, Wang Y, Liu T, Li W. PLoS One. microorganisms such as bacteria and macro organisms such as plants), filter water, recycle and purify waste and to provide food for the populations that leave riverside. Besar mangroves What we see on the surface is topsoil, and are loosely recognised as sandy or clayey types. Of the blue carbon sinks, mangroves have one of the highest organic matter (OM) storage capacities in their soil due to low mineralization processes resulting from waterlogging. In the surface layer, the mangrove soils treated with wastewater had significantly higher concentrations of NH + 4 ‐N, total and extractable P, total and extractable Cu, Cd, Zn and Mn. 2009 Sep;16(6):714-26. doi: 10.1007/s11356-009-0176-7.

Clipboard, Search History, and several other advanced features are temporarily unavailable. This study investigated soil characteristics and its relati An estuary‐based study in Florida revealed that soil salinity was relatively high downstream but low upstream (Chen & Twilley, 1999). Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. Hossain and A.A. Nuruddin: Abstract: Mangrove forests dominate the coastlines of tropical and subtropical climates of the world.

Within a given mangrove forest, different species occupy distinct niches. While total area of mangroves was a key determinant of total soil carbon storage, amongst the top 25 mangrove OCS holding nations, there was a nearly even split between nations with smaller area of high soil carbon density forests and those nations with lots of low soil carbon density forests (figure 4). Various soil physicochemical, microbial and enzymatic properties were analyzed. https://doi.org/10.1016/j.ecoleng.2016.01.062. Impacts of wetland dieback on carbon dynamics: A comparison between intact and degraded mangroves. Sci Total Environ. Copyright © 2017 Elsevier B.V. All rights reserved. Generally mangrove soils were higher in clay, organic matter, cation exchange capacity, aluminium, sulphate, iron and exchangeable bases than the non-mangrove soil.

This may be related to the soil characteristics of mangroves wetland, as the soil type in mangrove wetland is a typical acid sulfate soil, prolonged tidal flooding in the low tidal flat will lead to a significant increase in the pH of acid soil (Zhang et al., 1991). Abstract. We collected paired soil samples from each location, i.e., one soil sample from mangrove forest and its paired soil sample from adjacent rice fields.
