<br />.- <br />W <br />--:I <br />J-i' <br /> <br />20 <br /> <br />calculated for each sample using X=:2 hours and Y =: EC at 2 hours; <br />and 3) maximum EC (Y ) was calculated by using "b" from step (2) <br />max <br /> <br />and X=:5 hours, which was the maximum time that it took the 12 <br /> <br />test samples to reach maximum EC values. TDS and SMC were calcu- <br /> <br />lated for each sample based on estimated maximum EC for each sample. <br /> <br />Error was not determined for maximum EC or SMC. <br /> <br />The calculated SMC values were tested for inter- and intrabasin <br /> <br />relationships. Analyses of variance were conducted to determine the <br /> <br />significance of differences between SMC means for: soil and weathered <br /> <br />bedrock samples within each basin; collective soil and weathered bed- <br /> <br />rock samples from sample transects in each basin; and collective soil <br /> <br />and weathered bedrock samples for each basin within two sets of basins <br /> <br />according to underlying bedrock type. A T-test was conducted to <br /> <br />determine the significance of the difference between the SMC means for <br /> <br />collective soil and weathered bedrock samples of the two sets of basins <br /> <br />according to bedrock type. <br />
