Variation in soil and root acid phosphatases activity under PolyPs application at three P doses. Data are mean values ± SD (n = 8), Different lowercase letters above the bars indicate significant differences (p < 0.05) according to Tukey’s test. Asterisks indicate significant differences between P-fertilizers (P), P doses (D) and their interactions (P*D) (ns. not significant; *p < 0.05; **p < 0.01; ***p < 0.001)
