The basal associations (FA1 and FA2) are confined to a several thousand meters wide area (2-3 km along-strike width), and representing an up to 25-meter thick unit that laterally wedge out, being FA3 resting locally on the underlying Triassic sediments (Fig.
This crust is locally eroded in relation to the base of the overlying FA3.
A major change in facies architecture occurs at FA3.
On station trial carried out in Benin (unpublished data) showed that phosphorous application at the dose of 50 kg P ha-1 and inoculation with Bradyrhizobium strain FA3 is affordable and could be appropriate for soybean production.
Four strains of Bradyrhizobium japonicum were used for inoculum production: FA3, STM3043 and STM3045 strains obtained from Laboratory of Mediterranean and Tropical Symbiosis of Montpellier (France) and USDA110 strain from Laboratory of Soils Microbiology of Nairobi University (Kenya).
The main plot factor was inoculation with five variants (control, FA3, STM3043, STM3045 and USDA110) and the second factor was phosphorus with two levels (0 and 50 kg P2O5 ha-1), making ten treatments in total.
