How Phosphorus Influences Nitrogen Fixation in Legumes
Phosphorus is the silent gatekeeper of biological nitrogen fixation in legumes. Without adequate P, even the most elite rhizobial strains cannot deliver enough reduced nitrogen to sustain vigorous shoot growth. Farmers who balance both nutrients witness explosive biomass and protein gains that outpace single-element approaches. The following sections dissect the mechanisms, quantify the thresholds, and…
