Armstrong Memorial Research and Demonstration Farm

Lime Rates and Sources

Authors: ,


A lime rate and source study was implemented in 1996 at the Armstrong Research Farm to observe liming practices in no-till situations. The addition of lime to raise pH to 6.5 for row crops has been a long-standing recommendation. Those recommendations have included thorough mixing of the lime material with the soil which might be expected from normal tillage practices. This study will measure any corn and soybean yield changes, and the possible stratification of soil pH over time using no-till production practices.
