Researchers at the University of Natural and Life Sciences in Austria have conducted experiments with 15 soybean varieties, finding that the concentration of phosphorus in soybean grains is sufficient for the plant's development, even in low soil supply. The experiments also revealed that larger soybean grains have a higher concentration of phosphorus, which aids in forming a strong root system. This discovery suggests that reducing the use of phosphorus-containing fertilizers in soybean production could be a meaningful step in increasing the average yield of soybeans.
