Abstract : The largest crevasse in the Taquari River megafan in the Pantanal, Brazil with a perennial flooded area of ∼500,000 ha, was initiated in 1997 and impacted the environment and people. Here, we spatially characterize and explored a model aiming at predicting the evolution of the rechanneling of the Taquari River within this huge flooded area. Our approach is based on a spatiotemporal dry/wet index (R), which measures the degree of moisture in six major land cover classes. The index was annually estimated from MapBiomas Landsat rasters between 1996 and 2021 and calculated for 142 grid cells (5 × 5 km each). Temporal regressions were then used to predict the state of individual grids in the long term, up to 2080. The results suggest a gradual and slow terrestrialization between 1997 and 2021 as areas returned to pre-avulsion levels, mainly in the eastern and northern limits, closer to the crevasse. Modeling projections suggest that river rechanneling of the Taquari River might be completed by 2080 with its new mouth on the Paraguay-Mirim River. Large areas that are currently aquatic (open water, flooded soils, and flooded vegetation) are predicted to return to terrestrial state (forests and pastures) in the long term. |

Two greenhouse growth trials were performed to assess inoculation with phosphorus (P)-solubilizing microorganisms (PSM) in combination with alternative sources of phosphate in pearl millet (Pennisetum glaucum) cultivation: One using sandy soil and the other using clayey soil. The treatments comprised five P sources, with or without inoculation with PSM B119 (Bacillus megaterium) and B2084 (Bacillus subtilis) strains. Amendment of alternative sources (granulated, branned organomineral, and Bayovar rock) of P along with PSM inoculation produced more plant dry mass on sandy soil, which was not observed on clayey soil. Phosphorus use efficiency (PUE) did not differ between inoculated and non-inoculated treatments, and it was higher with the alternative P sources, compared to triple superphosphate (TSP) treatments. Available P content in the soil was higher with TSP, in sandy soil, and with PSM inoculation. Overall, acid and alkaline phosphatases and ?-glucosidase activity was higher in clayey soil, compared to sandy soil, which contains little organic matter; it was also higher with alternative P sources, compared to TSP, and in inoculation treatments, showing the potential of using PSM inoculation and alternative P sources to achieve higher sustainability and productivity in agriculture. |
