Relationship between plasticity index and soil erodibility: a case study of central Malaysian tropical soils [PDF]

Scientific Reports
Nations located in tropical rainforest regions, such as Malaysia, face a heightened risk of soil erosion due to persistently warm and humid climates. Soil erodibility (K), a critical parameter in erosion prediction models, is influenced by intrinsic soil

Spatial variations of nitrogen trace gas emissions from tropical mountain forests in Nyungwe, Rwanda [Discussion paper] [PDF]

, 2011
Globally, tropical forest soils represent the second largest source of N2O and NO. However, there is still considerable uncertainty on the spatial variability and soil properties controlling N trace gas emission. To investigate how soil properties affect
