The soil non-exchangeable potassium (K) pool contributes significantly to meeting crop K requirements. The objective of this study was to determine wheat and rice grain yield responses to different concentrations of sodium tetraphenylboron (NaTPB) extractable non-exchangeable K in soils. A field exp...
