Ecosystem-scale impacts of deforestation and land use in a humid tropical region of Mexico

Article Abstract:

An overview is presented on the soil chemistry effects of converting forest to pasture and agricultural land, using Mexico's Los Tuxtlas area as an example. Deforestation resulted in a loss of nearly 10% of combined soil and aboveground pools of sulfur and nitrogen, and approximately half of the combined soil and aboveground pools of carbon.

Soil carbon differences among forest, agriculture, and secondary vegetation in lower montane Ecuador

Article Abstract:

A comparison is presented between Ecuadorian crop cultivation, pasture types and forest growth in production of soil carbon. While pastures contained and produced a higher level of soil carbon than croplands, forest growth showed the highest levels; a discussion on reforestation and sustainable agriculture is also included.

Belowground consequences of vegetation change and their treatment in models

Article Abstract:

Research suggests that altered root distributions have a significant impact on soil chemistry. Topics include afforestation, deforestation, woody plant encroachment and herbaceous vegetation shifts.
