Soil pH continues to decline across much of the Palouse and the Pacific Northwest, primarily as a result of the application of nitrogen for the production of wheat and other crops. Standard soil sampling methodologies tend to overlook the problem of stratified acid soil layers that have developed in once neutral pH soils. Reduced tillage intensifies and narrows the layer of stratification compared to inversion tillage systems where more soil mixing occurs. Recently, the development of new technology pH meters has reduced or eliminated much of the time and expense of collecting samples and sending them to a lab to be tested.
