Sorghum and cowpea intercropping response to woody residue amendments in Sahelian agro-ecosystems of Burkina Faso
Daouda Guébré, Salifou Traoré, Koulibi Fidèle Zongo, Edmond Hien
In West African agro-ecosystems, soils are inherently low in soil organic carbon decreasing the capacity of soils to sustain crop productivity. Woody Residues instead of being burnt or exported out of the cropping systems, can be managed to optimize soil organic carbon build-up, nutrient cycling and crop productivity. The aim of this study was(...)

Influence of agroforestry systems on earthworm diversity and soil properties in a Sudano-Sahelian landscape
Adama Zoungrana , Mohamed Cissé, Mamoudou Traoré, Charles De Cannière , Babou André Bationo , Marjolein Visser, Salifou Traoré
Agroforestry systems promote a range of ecological base management to support sustainable agriculture. However, the influence of agroforestry management on soil biodiversity is still poorly investigated in SudanoSahelian landscapes. This study aims to guide sustainable management for soil biodiversity conservation in agroforestry systems by(...)

Mineralogical study of phosphate rocks by quantitative rietveld refinement
Jean-Baptiste Zoungrana , Brahima Sorgho , Corneille Bakouan , Saga Sawadogo , Regie Dimanche Ouedraogo , Boubié Guel, Philippe Blanchart
Phosphorites from the Kodjari deposits of Burkina Faso are composite rocks with a fine-grained matrix phase and
dispersed larger grains. Chemical analysis by XRF revealed a CaO content of 35.98 – 41.33 wt% and a P2O5
content of 26.85 – 30.75 wt%. X-ray diffraction patterns show the abundant presence of carbonate-fluorapatit(...)

Hydrochemical Characterisation of Groundwaters in a Crystalline Basement Environment: The Case of Fractured Aquifers in the Poni Watershed in the South-West Region of Burkina Faso, West Africa
Hebie, A., Kafando, S., & Nakolendousse, S
The Poni watershed is located in the south-west of Burkina Faso. Its geology is made up of fractured crystalline and crystallophyllian basement, where fractured aquifers are the most exploited for water needs. The aim of this study is to determine the physico-chemical characteristics of the groundwater in the fractured aquifers of the Poni wat(...)

Landform-regolith Map of the Central Goren Greenstone Belt, Burkina Faso
Benjamin Sawadogo ; Dominique Chardon ; Ousmane Bamba
The map is based on extensive fieldwork and complementary photo-interpretation. Field mapping was undertaken at 1:10 000 scale on the basis of a Lidar digital elevation model converted into topographic sheets with 1-m contours. Coverage of the study area required 60 days of fieldwork during the years 2017 and 2018. Around 300 km of itinerary w(...)

Fertilité des intrusions dans les porphyres cuprifères Paléoprotérozoïques de la ceinture de roches vertes Birimienne de Boromo, Burkina Faso, Craton Ouest Africain
Aristide BELEMSOBGO, Wendkouni Passecdé Pauline ZONGO, Urbain WENMENGA, Seta NABA
Le gisement de Cuivre-Or de Diénéméra-Gongondy est affilié à des porphyres cuprifères paléoprotérozoïques associés à la ceinture de roches vertes birimiennes de Boromo. La minéralisation est en relation avec un complexe intrusif basique à intermédiaire. La présente étude met en évidence le caractère fertile ou non de l’encaissant dans un envir(...)

Structural Controls of the Expansion of Small‐Scale Artisanal Gold of Bouda Area (Kaya‐Goren Green Belt, Burkina Faso) From Remote Sensing
R. A. I. Dao , H. Ilboudo , and D. Baratoux
Small‐scale artisanal mining is a vital sector of the economy of Burkina Faso. This activity, correctly regulated, remains essential for the population despite security issues since 2015. Exploration of new areas for gold mining in this condition is difficult but essential to continue extractive activities. It is, therefore, important to defin(...)

Caractérisation des processus orogéniques tardi-éburnéen par les mécanismes de mise en place des plutons alcalins de Wayen et de Déou
Abraham Seydoux TRAORE, Hermann ILBOUDO, Adama Ouédraogo YAMEOGO, Sâga SAWADOGO, Séta NABA
La structure et le contexte géodynamique de mise en place des granites alcalins ont été très peu étudiés.
Ces structures sont pourtant importantes pour interpréter les mécanismes de mise en place et déduire le régime tectonique qui a prévalu à la fin de l’orogénèse éburnéenne (actif ou inactif). L‘objectif de ce travail est d’utiliser la méth(...)

Morpho-pédologie et essai de classification des sols développés sur roches dolomitiques dans le bassin de Taoudéni au Burkina Faso
Fidèle KABORE, Boussa Tockville MARE, Joachim OUEDRAOGO, Idriss SERME, Prosper N. ZOMBRE
Les roches carbonatées ont été reconnues en régions tempéré et méditerranéenne comme des roches mères de sols calcimagnésiques et Fersialitiques. Les formations carbonatées du Burkina Faso en région tropicale, dominées par des dolomies magnésiennes, influent sur la pédogenèse des sols environnants. Ce qui laisse penser à une probable existence(...)
