Amazonian dark earths enhance the establishment of tree species in forest ecological restoration

Introduction Deforestation of areas for agriculture and cattle breeding is the leading cause ecological degradation loss biodiversity. The solution to mitigate these damages relies on techniques that improve soil health microbial quality degraded areas. Here, we demonstrate high nutrient microbiological contents Amazonian Dark Earths (ADE) can promote development trees used in restoration projects. Methods We from crops as control ADE Central Amazon conduct experiment, using 20% inoculum agricultural soil. Our goal was assess whether a small amount could changes plant similar its growth under 100%ADE. simulated conversion pasture forest area by planting U. brizantha all pots. After 60 days, removed it planted Cecropia pachystachya , Peltophorum dubium Cedrela fissilis . Results results demonstrated both 20%ADE 100%ADE treatments increased productivity and, consequently, carbon stock. Also, treatments, P. C. had better development, with plants showing performance those Both showed numbers taxa, being significantly higher than Discussion sufficient increase richness soil, providing several beneficial microorganisms tree species such Pedomicrobium Candidatus Nitrososphaera members Paenebacillaceae. Nevertheless, common pioneer Forest response even corresponding lower taxa number other two species. In conclusion, point out structure remains very among but dissimilar highlighting role an enhancer microbiota enrichment rhizosphere. use alter community. Therefore, believe our data contribute speeding up programs adopting new biotechnological approaches ecology.
