Mitscherlich relationship of plant-available soil P (DL, CAL, and DGT) with crop response. n = 48; response was modeled using the Mitscherlich equation. Significant coefficients of determination (R2) were highlighted with *(P < 0.05), **(P < 0.01), and ***(P < 0.001). DL double-lactate, CAL calcium acetate lactate, DGT diffusive gradients in thin films
