The Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock
Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...
متن کاملThe influence of watershed land use on lake N : P in a predominantly agricultural landscape
This study tests the hypothesis that lakes in watersheds dominated by row-crop agriculture (e.g., maize or soybeans) have systematically higher N : P than lakes in watersheds with large tracts of pasturelands. Current biogeochemical models of eutrophication suggest that agricultural nitrogen and phosphorus fluxes lead to a systematic decline in the N : P of receiving waters. In contrast, differ...
متن کاملlinking soil organic carbon stocks to land-use types in a mediterranean agroforestry landscape
in agroforestry landscapes, land use, and the associated management practices exert strong impacts upon soil organic carbon stocks. data on the soil organic carbon were collected for different land-use types within a small watershed, el salado, located in lanjarón (se spain). eight land-use types namely: farmland planted in olive, almond, and cereals; forest with pinus halepensis mill. and pinu...
متن کاملDetermination of Appropriate Land Use by Using Land Use Planning Process in Sykan Watershed of Ilam Province, Iran
Objective: The aim of this study is to provide a management plan for the Sykan watershed of Darre shahr city located in Ilam province using GIS in land use planning. Methods: For land using of Sykan watershed of Ilam province with about 9 hectares area, map of classes, elevation, percent slope, geographical aspects, soil characteristics, vegetation density and the final map units were combined ...
متن کاملImpact of Land Use Changes on some Soil Micromorphological Features in Rakat Watershed, Eastern Khuzestan Province
The objective of this study was to investigate the impact of land use change (forest and rangelands to agriculture) on some micromorphological indices of soil quality in part of Rakat watershed, southwest of Iran. Accordingly, intact soil samples from 0-15 and 15-30 cm depths were collected from the above-mentioned land uses, and microstructure, type and abundance of voids, redoximorphic featur...
