The Amazon has one of the largest bauxite reserves in the world and the growing demand for this ore intensifies environmental impacts and, consequently, the necessity of ecosystems restoration. In this sense, the monitoring of indicators is essential to ensure the restoration success. The objective of this study was to evaluate indicators of ecosystem restoration in areas degraded by bauxite mining in the eastern Amazon, Brazil, under three different restoration methods: Nucleation (NC), Seedling planting (SP), and induction of natural regeneration (NR) in comparison with a reference forest (RF). Structural and compositional indicators, including density, frequency, and dominance, as well as the Importance Value Index (IVI) of tree species, mortality, conservation status, diversity indices, and Mean Annual Increase in height and diameter (MAIH and MAIDBH) were assessed. Solanum crinitum, Cecropia distachya, Senegalia polyphylla, and Qualea grandiflora were the most important species according to IVI for SP, NR, NC, and RF, respectively. In SP, MAIH and MAIDBH were higher than in the other treatments, however, the difference between methods was not of significant. The diversity indices of the three restoration methods tested were close to those of RF. Four species with some conservation status were identified; Cedrela odorata, Genipa americana, Swietenia macrophylla, and Hymenaea parvifolia, all native to the eastern Amazon. Thus, through the indicators, we found that all restoration methods showed positive indicators of restoration and a gradual return of the structural characteristics of the vegetation.

There are concerns related to the application of phosphate fertilizers to weathered soils that present low soil test phosphorus (STP) due to P adsorption in iron oxyhydroxides. Furthermore, long-term trials are needed to evaluate crop response to corrective P fertilization and its interaction with different maintenance P fertilization strategies in these soils. An experiment involving the combination of three initial corrective P fertilization schemes (control without P correction or with the application of 105 kg P ha−1 as triple superphosphate [TSP] or reactive rock phosphate [RRP]), four Pmaintenance strategies (a controlwithout the application of maintenance P, or 35 kg P ha−1 yr−1 as TSP, RRP, or a mix of both) and two application methods was cultivated during 16 yr at the Embrapa Cerrados experimental station in Planaltina, DF, Brazil. Corrective P fertilization promoted an early crop yield response. In contrast, high crop yields were only obtained in control treatments with no corrective P fertilization after soil P stocks were increased to a minimum level. With increasing P stocks, broadcast application resulted in slightly better yields. The required residual P stocks in soil to obtain high yields were estimated as equivalent to 113.6 and 205.2 kg P ha−1 for TSP and RRP, respectively. These values allow for STP contents to increase to critical levels, whose value for TSP of 4.1 mg kg−1 Mehlich-1 P is below that recommended for the region, possibly due to the contribution of organic P forms in the long-term no-tillage system MenosThere are concerns related to the application of phosphate fertilizers to weathered soils that present low soil test phosphorus (STP) due to P adsorption in iron oxyhydroxides.
