This capacity of water conservation in the aerial part is related to the low hydraulic conductivity in the plant that reduces the turgor pressure of the cells and promotes stomata closure.
For each sampling point, the penetration, moisture, bulk density, total porosity and particles density of soil at 0.0--0.10, 0.10--0.20, and 0.20--0.30 m depth, and hydraulic conductivity on saturated soil surface were measured.
The evaluation of salt leaching requires a numerical model that can simulate water and solute transport and enumerate cation exchange, mineral dissolution and precipitation and changes in soil hydraulic conductivity in relation to the modification of soil chemistry (Simunek and Suarez 1997; Goncalves et al.
Statistical analysis: The data generated for soil moisture content, soil temperature, soil bulk density, soil air filled porosity, water stable soil aggregates, water holding capacity, hydraulic conductivity, matrix flux potential and root growth were subjected to statistical analysis using the statistical package SPSS 13.0 software (Analyse - General Linear Model - Univariate) (SPSS Inc., Chicago, USA).
Each layer was hydrated to ensure hydraulic conductivity.
[7] used a newly developed parameter to measure unsaturated soil hydraulic conductivity by applying the steady flow method and direct measurement of matric suction.
where [K.sub.x] (h), [K.sub.y] (h), and [K.sub.z] (h) represent hydraulic conductivity in the x, y and z axis, which are all functions of the pore water pressure head h when unsaturated.
Concerning the values of saturated hydraulic conductivity presented in Table II, in nine of the ten samples analyzed they were higher in the retention curve model and the difference was noticeable in five of the soils analyzed.
Geotechnical and geoenvironmental engineers have found it necessary to devise an engineering approach to achieve the appropriate hydraulic conductivity and other required properties.
