Resumo
Agroforestry systems have been one of the most promising options for the production of African mahogany, as they reconcile the planting of forest species with agricultural crops and / or animal husbandry, providing environmental, social and economic benefits. The objectives of this research was to evaluate the dynamics of the chemical and biological attributes of the soil in agroforestry systems with African mahogany, in
comparison with soil under conditions of native vegetation in the municipality of Nazário - GO. The treatments were composed of three soil management systems: S1: African mahogany in monoculture since 2013; S2: African mahogany in an agroforestry system implanted since 2015, grown with cocktails of different species; S3: African mahogany in an agroforestry system implemented since 2013, grown with cocktails of different species. For the control treatment, the soil in the forest with native vegetation of the Cerrado (Mata) was evaluated. The chemical and biological attributes of the soils were analyzed in a randomized block design, with six replications. The results obtained indicate that the different management systems influenced the chemical attributes of the soil. The monoculture of African mahogany provided the largest accumulation of organic matter in the soil when compared to agroforestry systems and native vegetation, demonstrating its potential for the cultivation of this forest species. There were distinct changes in the biological attributes of the soil by each management system. The management systems with African mahogany in an agroforestry system implemented in 2015 (S2) and in 2013 (S3) had the highest carbon content of microbial biomass and basal soil respiration, respectively. The native forest had the highest nitrogen content in the microbial biomass. And African mahogany in a monoculture system had the highest total carbon content.
