Profiling of microbial PLFAs: Implications for interspecific interactions due to intercropping which increase phosphorus uptake in phosphorus limited acidic soils

► A field experiment with maize-based intercropping in acidic soils was conducted. ► Interspecific stimulation of P uptake was generally controlled by soil P status. ► Rhizosphere acidification was not the cause for increased P uptake in acid soils. ► Root contact modified the microbial community and dominant microbial species. ► Microbial interaction may contribute to increased P uptake during intercropping.
