Potassium (K) deficiency in wine grapes results in reduced vine growth, premature leaf drop, and yield and color loss. K can be fixed in the interlayer of clay minerals in a process called K fixation, which leads to high spatial variability in soil K

Soil tests commonly used to develop potassium (K) fertilizer recommendations, such as extraction by 1 M ammonium acetate (NH4OAc) at pH 7, measure both soluble and exchangeable K. In soils that fix K so that it is no longer exchangeable, although a p
