In Mali, the deficiency of agricultural soils in phosphorus is one of the limiting factors in crop production. They respond well to phosphorus fertilization, but the high price of imported chemical fertilizers limits their use by the producers. However, Mali has large deposits of natural phosphate in the Tilemsi Valley (PNT) in northern Mali. Faced with …

Phosphate fertilizers are dependent on phosphorus derived from phosphate rock, which is a non-renewable resource and current global reserves may be depleted in 50–100 years (Cordell et al., 2009). Therefore, exploring alternative forms of agriculture, where nutrient conservation is key, is of vital importance. ... Effect of Tilemsi phosphate ...

This work aims to identify, isolate and characterize Tilemsi rock phosphate (TRP) solubilizing Thiobacillus strains in various agricultural soils. Obtained results showed that the analyzed soils are poor in Thiobacillus and that the quantity of acid produced and TRP solubilized is directly proportional to the growth of these bacteria.

Phosphate-solubilising microorganisms have been studied widely in alkaline and calcareous soils (Wakelin et al., 2007; Meyer et al., 2017), where acidification is considered as a key mechanism for P solubilisation. Acidification leads primarily to the dissolution of Ca-P minerals, which more commonly occur in higher pH soils.
