If total sulfur analysis is relatively <br />high and the CaCO3 equivalent low, the results would indicate a negative acid base <br />potential. If a large negative acid-base potential is the resuR then additional sampling to <br />include Pyritic Sulfur and SO4-S will be run for that sample. <br />(2) SAR < 12+ Percent Saturation < 80, > 40% clay. <br />SAR > 10+ Percent Saturation > 80, < 359'° clay. <br />261 c <br />°,.~5° <br />~ gl,ylgo <br />
