Effects of a rock phosphate on indigenous rhizobia associated with Sesbania sesban.
J Environ Manage. 2012 Mar; 95 Suppl:S265-8.JE

Abstract

Tilemsi rock phosphate (TRP) of Mali is one of the most promising rock phosphate in West Africa for soil fertilization, but it is little used because of its insoluble form. The main objective of this study is to investigate TRP effects on rhizobia associated with the multipurpose leguminous tree Sesbania sesban grown on a sandy soil, poor in phosphorus and not sterilised. The experiment included treatments with and without TRP and was conducted during 105 days. At the end, 114 nodules have been collected and analysed by PCR/RFLP of 16S-23S intergenic spacer. Sixteen different RFLP profiles corresponding to different genomic groups of rhizobia have been detected. Five were dominant and present in both treatments. Five groups appear only in treatments without TRP whereas the six others are only in nodules of plants with TRP, suggesting a different capacity of natural phosphates solubilization by these strains.
