Journal ArticleDOI
Geochemical variations in aeolian mineral particles from the Sahara-Sahel Dust Corridor.
Teresa Moreno,Xavier Querol,S. Castillo,Andrés Alastuey,Emilio Cuevas,Ludger Herrmann,Mohammed Mounkaila,Josep Elvira,Wes Gibbons +8 more
TL;DR: Dusts blown into the Sahara-Sahel Dust Corridor from sub-Saharan Africa during the summer monsoon source from deeply chemically weathered terrains and are therefore likely to be more kaolinitic and stripped of mobile elements, but retain immobile and resistant elements.
Journal ArticleDOI
Review of methodologies for extracting plant-available and amorphous Si from soils and aquatic sediments
TL;DR: There is a variety of methodologies used in the aquatic sciences and soil sciences for extracting different forms of Si from sediments and soils as mentioned in this paper, however, a comparison of the published extraction techniques is lacking.
Journal ArticleDOI
Wind‐blown nutrient transport and soil productivity changes in southwest Niger
TL;DR: In this paper, during two convective storms, mass fluxes of wind-blown particles were measured in a pearl millet (Pennisetum glaucum) field in southwest Niger, on a sandy, siliceous, isohyperthermic Psammentic Paleustalf.
Journal ArticleDOI
Trace element variation in size-fractionated African desert dusts
S. Castillo,Teresa Moreno,Xavier Querol,Andrés Alastuey,Emilio Cuevas,Ludger Herrmann,Mohammed Mounkaila,Wes Gibbons +7 more
TL;DR: In this paper, the authors used inductively coupled plasma atomic emission spectrometer (ICP-AES) and inductively coupling plasma mass spectrometry (ICp-MS) to analyze dust samples from Western Sahara, Algeria, Chad and Niger.
Journal ArticleDOI
Soil and crop growth micro-variability in the West African semi-arid tropics: a possible risk-reducing factor for subsistence farmers.
TL;DR: In this paper, the authors studied the impact of soil and crop growth variability on subsistence farming systems in the semi-arid tropics of West Africa, where nutrient and water availability alternate in limiting agricultural production.
