Soil quality with traditional management in the Chambira native community

Abstract

The traditional management applied by the Native Community of Chambira (NCCh) is based on agroforestry plots with diverse species and areas with rotation of legumes, cassava and maize. The objective was to evaluate behaviour of the physicochemical indicators of soil quality with traditional crop management in the NCCh. A completely randomised design was applied, where the treatments were traditional mixed fruit management (MF), crop rotation (CR) and native forest (NF) as reference. Physical indicators of the surface layer did not show differences, the apparent density (AD) and the resistance to penetrability (RP) increased with depth; chemical indicators differed in the MF and CR had higher results compared to NF. The AD and RP had a significant negative correlation with soil organic carbon (SOC) and positive correlation between SOC, P, Ca, Mg, K available and cation exchange capacity. The MF and CR managements developed in the NCCh are techniques with great potential for soil conservation.
