Litterfall production, decomposition and litter nutrient contents in a mined area revegetated with different forest species
29/Mar/2023
ABSTRACT Afforestation of sites disturbed after bauxite mining is the favorite technique to restore all ecosystem functions. The nature of the tree species used for revegetation of post-mining land can accelerate the recovery of soil organic matter and nutrient cycles. This study aimed to determine the litterfall production, decomposition rate and nutrient content from three types of forest cover ( Eucalyptus , Anadenanthera peregrina , mixed plantation of 16 native species) planted in a bauxite mining area in recovery. Litterfall […]
Growth, Biomass and Carbon Stocks in Forest Cover Planted in an Area of Bauxite Mining in Rehabilitation
26/Nov/2019
ABSTRACT Forest cover in areas degraded by mining is an alternative way of mitigating CO2 concentrations in the atmosphere by fixing C in tree biomass. This study evaluated the growth and C stocks of forest cover in an area of bauxite mining with four sources of fertilizer. Height (Ht), diameter at ground level (DGL), and diameter at breast height (DBH) were determined in Anadenanthera peregrina (Ap), clonal Eucalyptus (Euc), and a mixed plantation of 16 native forest species (Nat) at […]
Revegetation with cover crops for soils under arenization and wind erosion in Rio Grande do Sul state, Brazil
01/Feb/2008
The degradation of soils with high sand content, in the southwest of the state of Rio Grande do Sul, is due to the vegetal cover withdrawal, forming sandy areas called “areais”, which pose a risk to animal husbandry and the prairie ecosystem. A technique of revegetation with cover crops such as Avena strigosa Schieb. and Lupinus albescens H. et Arn., was developed to reduce the soil particle movement by eolic erosion. The experiment was carried out on a Quartzipsament soil, […]
Deposition and decomposition of litter of four years old Mimosa caesalpiniifolia, Acacia mangium, and Acacia holosericea in a planosol
01/Dec/2000
Some of the leguminous tree associated to fixing bacteria and micorrizal fungi have good development in degraded soils. Aiming to evaluate the influence of these species on soil fertility level, dry matter production and the nutrient contents of litter originated from these plants were measured during 1995. The rate of litter decomposition was evaluated by analysing the material collected in 1995 and 1996. Homogeneous stands of Caesalpiniifolia mimosa (‘Sabiá’), Acacia mangium and Acacia holosericea established at the experimental station of […]
