of 3 tons of pure calcium carbonate and to 95.52% by the same material at the rate of 5 tons per acre. Similar amounts of pure calcium carbonate effected larger changes in the degree of saturation of Shelby loam and Tama silt loam. Quarry-run limestone induced considerably smaller changes than did the pure calcium carbonate. Hydrated lime and ~oo-mesh limestone had about the same effects, while the coarser materials were considerably less effective in increasing the degree of saturation. Pure magnesium carbonate was slightly more effective than pure calcium carbonate, but calcium limestone was more effective than dolomitic limestone. In field tests the degree of saturation of Grundy silt loam was increased in 6 months from 65.75% in the untreated soil to 70.86% by the application of 3 tons and to 79.4~% by 6 tons of quarry-run_limestone. Hydrated lime and ~oo-mesh limestone were considerably more effective than twice as much quarry-run limestone in increasing the degree of saturation of this soil with bases.
