The acreage of alfalfa is increasing rapidly in the northern part of the bluegrass region of Kentucky. A small part of the crop is grown on land that has been limed. Most of it is grown where the natural reaction of the land is favorable for the crop. The topography of much of this section is that of long, steep slopes with narrow ridge tops. A part has shorter, less steep slopes and the ridges are widened out into considerable areas of undulating, land. The soil is of limestone origin. Growth of alfalfa without liming is attempted for the most part only on the steeper slopes. The undulating land is limed before seeding to the crop. Most of the section can be correctly placed with reference to need for liming for successful growth of alfalfa on the basis of topography. On part, however, the need for liming cannot
