Carbon storage in soils of Southeastern Nigeria under different management practices
BACKGROUND Changes in agricultural practices-notably changes in crop varieties, application of fertilizer and manure, rotation and tillage practices-influence how much and at what rate carbon is stored in, or released from, soils. Quantification of the impacts of land use on carbon stocks in sub-Saharan Africa is challenging because of the spatial heterogeneity of soil, climate, management cond...
متن کاملImpact of Land Use Changes on some Soil Micromorphological Features in Rakat Watershed, Eastern Khuzestan Province

متن کاملEffects of converting forest to the rainfed lands on soil characteristics in a part of Zagros forests
The forest soils are the key parts of the Earth system that are globally degraded through anthrop induced deforestation, mainly converting to other landuses. The present study was conducted in Gazafolya village located in Merek watershed, Kermanshah, Iran, in which the soil quality of the forest and converted forest (rainfed lands) with the same topographic and geologic conditions were compared...
