Pearson correlations showing the association between rhizosphere acid phosphatase activity (RS-APase: µmol g−1soil 30 min−1), rhizosphere available phosphorus (RS-Pavailable: mg kg−1), soil pH and forage production (FP: Mg ha−1) for corn soybean monocropping and intercropping treatments. ns = correlation is not significant; *Correlation is significant (p ≤ 0.05); (**p ≤ 0.01); (***p ≤ 0.001) and n is 66 for all parameters.
