Hydropedological behavior of a chromic vertisol under different plant covers

Vertisols present edaphic limiting factors primarily of a physical nature. The study their hydropedology, supported by multivariate techniques, is vital importance. work was developed with the objective determining, through analysis, hydropedological behavior Chromic Vertisol under different plant covers. In areas natural grass, sugarcane, and secondary forest, belonging to Holguín Sugarcane Provincial Research Station, three random points were chosen in each. Soil penetration resistance, soil bulk density, gravimetric moisture, volumetric moisture at depths 0-10, 10-20 20-30cm determined. A Principal Component Analysis Canonical Correlations performed using Statistica 7 Statgraphics Plus XV.II. first two components made greatest contribution variance, 83.09%. contributions (1st component) given all compaction depth 20-30 cm. 2nd component influenced 0-10 10-20cm layers. There contrast between variables that characterize solid phase which they describe liquid soil. correlation compaction. pairs canonical showed strong linear regularly dispersed along central values model, remarkable grouping depths.
