OSU researchers released higher pH targets as part of improved lime rate recommendations after they took soil tests from across the state.
New research from the OSU Soil Fertility Program provides improved lime rate recommendations for both Sikora and SMP buffer methods, including higher pH targets up to 7.2. Twenty-four acidic soils from across the state were tested using laboratory lime incubation trials to determine the lime needed to reach target soil pH values ranging from 5.6 to 7.2. This work led to updated lime requirement estimates for each target.
