LIME-REACTIVITY OF ILLINOIS SOILS

THE LIME-REACTIVITY OF 38 ILLINOIS SOILS WAS STUDIED. LIME REACTIVITY IS DEFINED AS THE INCREASE IN THE UNCONFINED COMPRESSIVE STRENGTH OF CURED SPECIMENS OF LIME-TREATED SOIL OVER THAT OF SPECIMENS OF UNTREATED SOIL. THE RELATION OF LIME-REACTIVITY TO A NUMBER OF SOIL PROPERTIES AND CHARACTERISTICS WAS DETERMINED. IT WAS CONCLUDED THAT' 1. SOIL ORGANIC MATTER GREATLY RETARDS THE ACTION OF LIME. 2. A SOIL PH OF OVER 7 INDICATES GOOD REACTIVITY. 3. THE A HORIZON IS NOT REACTIVE WITH LIME. 4. B HORIZONS MAY BE EITHER NON-REACTIVE OR REACTIVE. 5. C HORIZONS ARE SATISFACTORILY REACTIVE. 6. GREATER REACTIVITY IS ALSO ASSOCIATED WITH /A/ GREATER CONTENTS OF MONTMORILLONITE PLUS MIXED-LAYER CLAY MINERALS, /B/ SLICK SPOTS, /C/ A LOW DEGREE OF WEATHERING. 7. THE FOLLOWING DO NOT SIGNIFICANTLY INFLUENCE REACTIVITY /A/ LL AND PI, /B/ GROUP INDEX, /C/ MINUS 2-MICRON CLAY CONTENT, /D/ CATION EXCHANGE CAPACITY, TOTAL EXCHANGEABLE BASES, SPECIFIC EXCHANGEABLE BASES. /BPR/.
