Two samples,from A and B horizons of the topsoil, are of • particular interest. Conductivities of both extracts, Nos. 38 and 37, are seem to be very loc•~, 0.19 and 0.07 mmhos/cm, respectively, which have equivalent dissolved salt concentrations of 1.5 and 3.5 meq./L. From such low concentrations, it appears a large portion of the soluble salts, which may have existed in the topsoil at one time, have been leached away over an indeterminate period of time. pH is an equally important characteristic of soil extracts. By what is found in Table V, it appears the extract solutions are, at worst, mildly alkaline; Chat is, pH values are X8.0, and they are dilute solutions. On 1y one extract, No. 24, has a pH exceeding 8.0, pH equals 3.25, and such a pH is not considered strongly alkaline. In summary, pH salt concentrations • to salt contents in sufficiently saline permitted to drain and conductivity tests indicate dissolved in 1:1 extracts from overburden are comparable surface runoff. Such solutions do not appear or alkaline to consider them a hazard if into the surrounding caater shed. Chemical Analvses of Extract-Solutions (1: 1) Table VI shows recorded data for separate cation and anion concentrations found in extract solutions, without dilution corrections. Corrected data next appear in Tab1e~VII. These represent the dissolved cations and their concentrations found in the original extract solutions, before dilution. According to the data in Table VII, column 3, the smallesC amounts of sodium (Na+) were extracted from samples 38, 37 and 3G, which represent A and B horizon soils and the subsoil immediately adjacent. Concentrations of Na+ in the three extracts measure) 0.125, 0.154 and 0.109 meq./L, respectively. Obviously sodium • ions must have been ].cached from the A and B horizons and the subsoil, to a depth of ~28 feet, someCimc in the past. OL'her- wise, dissolved Na+ con ten Ls would be greater.
