Soil acidity is one of the most important problems before Iowa farmers at the present time. The following questions regarding lime and Its use on land are constantly being asked:
How may I determine whether my soil is acid and in need of lime? Is lime a fertilizer? How much lime is needed per acre? What is the most desirable form of lime to use? Where may I get limestone and how much does it cost? What is the best method of spreading lime and when should it be applied? Will it injure the land? How often will lime need to be applied? Does it pay to use limestone?
This circular has been prepared to answer these questions and to give further information on this subject.
