Relationship between hydraulic conductivity (top) and sand and hydraulic conductivity and the sodium (Na+)/electrical conductivity (EC1:1 ratio (bottom) in samples collected from three landscape positions and five soil depths in 2018.

The sand, clay, pH, electrical conductivity (EC1:1), apparent cation exchange capacity (CECa) sodium (Na+), %Na+, Na+/EC ratio, hydraulic conductivity (con.), and drainable porosities of soil samples collected from five soil depths and three landscape positions in 2018. The standard deviations (sd) are provided adjacent to the means. For the means and standard deviations, n is 4. The standard deviations of the mean (sdx) across depths are also provided. The n for these calculations was 20.

Correlation coefficients between pH, ammonium acetate sum of bases (CECa) electrical conductivity (EC1:1), sodium (Na+), %Na+, Na+/EC ratio, sand, clay, silt, bulk density (BD), pore space (PS), water content (wc) at field capacity (g g-1), water content at field capacity (g cm-3), hydraulic conductivity, and drainable porosity (DP) in samples collected from the subsurface soil samples collected across the three landscape positions in 2018. Correlation values greater than 0.288 or less than –0.288 are significant at the 0.05 level. Correlation values greater than 0.372 or less than –0.372 are significant at the 0.01 level.
- Table 3
The temporal changes (2019 to 2018) in the electrical conductivity (EC1:1), ammonium acetate extractable sodium (Na+), and the Na+ to EC1:1 ratio measured in five soil depths and three landscape positions. The 95% confidence interval (CI) for each soil depth and landscape position value are provided. A negative value indicates a decrease from 2018 to 2019.
