Phosphorus availability and microbial community in the rhizosphere of intercropped cereal and legume along a P-fertilizer gradient
Background and aims Positive below-ground interactions (facilitation) should be more
pronounced when resources limit crop growth, according to the stress-gradient hypothesis.
Our aim was to test this hypothesis for intercropped durum wheat and faba bean along a P-
fertilizer gradient. Methods A field experiment was conducted in a long-term P-fertilizer trial
with three rates of P-fertilization (No, Low and High P). Microbial biomass was assessed by
chloroform fumigation-extraction. Quantitative PCR was applied to evaluate the abundance …
