Intercropping legumes and cereals increases phosphorus use efficiency; a meta-analysis (2020, background): “The benefits of cereal-legume intercrops for P uptake and yield depend on species combination (He et al. 2013), soil P availability, and P input levels (Tang et al.”
Phosphorus availability and microbial community in the rhizosphere of intercropped cereal and legume along a P-fertilizer gradient (2016, methodology): “According to the stress-gradient hypothesis, the frequency of positive interactions increases at higher environmental stress (e.g. at lower nutrient availability), while negative interactions (competition) dominate when conditions are less stressful (Maestre et al. 2009; He et al. 2013a).”
