Potassium buffering capacity and corrective potassium fertilizer recommendations in soils from Southern Brazil

Potassium buffering capacity and corrective potassium fertilizer recommendations in soils from Southern Brazil

ABSTRACT Soils with low potassium (K) availability require corrective fertilization for grain crops. The recommended rate to increase K availability up to the critical level depends on the soil K buffering capacity (KBC). This study aimed to quantify the KBC and recalculate the rates necessary to re...
