dc.descriptionObjective: To evaluate the agronomic efficiency of nepheline syenite (NS) as a potassium (K) source for soybean and maize crops during the 2021/2022 and 2022/2023 growing seasons, in comparison with KCl. Method: The experimental design was a randomized complete block with four replications. The K rates applied were 0; 70, and 140 kg K₂O ha⁻¹. For the 140 kg K₂O ha⁻¹ rate, eight plots were established: four were evaluated in both the first and second seasons, and four were evaluated only in the second season, when they received an additional 70 kg K₂O ha⁻¹, resulting in a total of 140 + 70 kg K₂O ha⁻¹. Results and Conclusion: Soybean yield with NS was similar to the control and lower than that obtained with KCl in the 2021/2022 season. In the following season, 140 kg K₂O ha⁻¹ applied via NS increased soybean yield by up to 8%. In maize, the highest yields were obtained with 140 + 70 kg K₂O ha⁻¹ applied via NS (7%) and KCl (8%). At this rate, final soil K contents increased by up to 26% with NS. A residual effect of NS was observed, as well as similar agronomic efficiency between NS and KCl at the 140 + 70 kg K₂O ha⁻¹ rate.
