Soil Genesis, Phosphorus and Micronutrients of Selected Vertisols and Associated Alfisols of Northern Cameroon
An integrated soil genesis, phosphorus and micronutrient (Fe, Mn, Cu, Zn) study was conducted for seven northern Cameroon Vertisols and associated Alfisols. Vertisols developed from Precambrian schist are classified as Entic Pellusterts. Similar soils developed from Quaternary lacustrine and fluvial sediments are classified as Typic or Entic Pellusterts and Entic Chromusterts. The Alfisol is developed from Precambrian granite and is classified as an Arenic Haplustalf. All soils are developed under an isohyperthemic temperature regime (mean annual temperature, 27° to 30°C) and an ustic soil moisture regime (mean annual rainfall, 600 to 900 mm). Those developed on nearly level fluvial plains are seasonally flooded. All Vertisols crack to the surface but lack gilgai microrelief. They are dominantly dark gray to grayish brown. All soils are very compact and dense (1/3 bar bulk density, 1 to 1.6 g/cm3). Clay contents generally exceed 40% in the control section. Organic carbon is low (

The Impact of Climate Change on Sub-Saharan Africa
While global warming and its consequences on humanity are being fiercely debated at the global scale, deliberate and pragmatic reflections on the subject in Sub Sahara Africa remain muted. This book examines how global climate change impacts the area, the measures and strategies to face it and actions presently implemented in combating it.
