Abstract
Soil analysis, especially nitric acid extraction of potassium appears to be a very useful means of diagnosing potassium-deficient soils in California. Studies reported here compared two analytical methods for determining soil potassium levels. Plant growth responses were determined by greenhouse pot tests.
