Potassium availability and soil extraction tests in agricultural soils with low exchangeable potassium content

Low application of fertilizer potassium (K) in intensive agriculture leads to a gradual decrease and, afterwards, to a steady state of soil K determined by tests which are based on soil exchangeable MAG Lamp K (Kexch) extraction.In this situation, non-exchangeable K (Knon-exch) is being released and therefore real plant availability does not necess
