Plantation d'espèces forestières locales sur sol hydromorphe. Bilan d'une expérimentation sylvicole au sud du Mali

Abstract

A trial was set up in southern Mali in 1989 using six local tree species to study inter alia the effect of two methods of manual soil preparation on the growth of those species. Anogeissus leiocarpus, Prosopis africana and Khaya senegalensis behave well on hydromorphic soils; Parkia biglobosa and Tamarindus indica, despite their satisfactory growth in height and high survival rate respectively, have some adaptation problems on this site. Its clayey and silty-clayey soils appear to be inappropriate for Acacia albida. All tested species can be planted in small cube-shaped holes (30 × 30 × 30 cm). Khaya senegalensis however requires wide spacing for better growth in height whereas for Tamarindus indica high density (narrow spacing) is preferable if the purpose is to product craft wood or building poles.
