Figure 3

Rhizosphere soil acid phosphatase (µmole pNP g−1 soil 30 min−1) activity of corn and soybean cropping systems. The error bar represents means ± SE of combined data collected in 2016 and 2017 field seasons. Different letters indicate significant differences between the cropping systems at alpha 0.05. Mono-(US): monocropping of upright soybean; Mono-(VS): monocropping vine soybean; Inter-(US): intercropped upright soybean; Inter-(VS): intercropped vine soybean; Mono-C: monocropping corn; Mono-S: monocropping soybean.
