Lime requirement of 9 Michigan soils was determined by incubating the soils for 13 weeks in the greenhouse after addition of varying rates of agricultural limestone. The initial pH of all soils was approximately 5.5. Lime requirement was correlated with cation‐exchange capacity, organic matter content, exchangeable hydrogen per 100 g. soil, clay content, and lime requirement measured by the Shoemaker, McLean, and Pratt buffer method. Increase in soil pH after liming was significantly correlated with increase in percent base saturation within each soil type, but not between soil types. Liming did not appreciably affect the amount of exchangeable Mg and K or extractable P in the soils. At pH 5.5, liming increased yield of alfalfa on 6 soils, but not on the remaining 3 soils. Low yields were correlated with low calcium content in the plants.
