Effects of Different Exogenous Additives on Phosphorus Uptake in Soybeans

Phosphorus is a core nutrient element for soybean growth and development, and its absorption efficiency directly affects biomass accumulation and yield formation. Recent studies have shown that exogenous substances such as riboflavin, oxalic acid, and luteolin can significantly enhance soybean phosphorus uptake by regulating root physiological characteristics, improving soil phosphorus availability, and enhancing stress resistance. This article systematically reviews the mechanisms and synergistic effects of these three types of substances, providing a theoretical basis for the precise regulation of efficient phosphorus utilization in soybeans.
