Central Vietnam , Eucalyptus urophylla, soil quality index (SQI)Abstract
The Soil Quality Index (SQI) for Eucalyptus urophylla plantations in the central provinces of Vietnam was developed based on ten soil indicators including bulk density, sand, silt, clay, pH (KCl), organic carbon, total nitrogen, available phosphorus and potassium and cation exchange capacity. The results revealed significant correlations among several of these indicators. Using Pearson correlation analysis and principal component analysis (PCA), three key indicators including sand, organic carbon and available potassium were selected as the minimum data set (MDS) for SQI construction. The resulting index indicated that the soils in Eucalyptus plantations in the study area were of moderate quality (0.44). This SQI can serve as a practical tool for rapid soil quality assessment in Eucalyptus plantations and for long-term soil monitoring programs.
