eLibrary Editor’s Note:  In the original 1999 Soils Home Study Course book, two publications are referenced under the section, 'To Lime or Not to Lime?':  NebGuide G74-153 (Frank, K.D. and Delno Knudsen, Understand Your Soil Test:  pH - Excess Lime - Lime Needs, University of Nebraska Cooperative Extension) and NebGuide G84-714 (Delno Knudsen, Estimating Ag Lime Quality, University of Nebraska Cooperative Extension).  Please be advised that these publications are no longer in print; and, therefore, have been replaced in this online lesson by the two more recent NebGuide issues listed above.
