In a study on soybeans, adding special bacteria and phosphorus to the soil increased the yield and quality of the crops. Using a combination of 19.65 kg of phosphorus with the bacteria gave the best results, producing higher seed yield, oil yield, and protein content. This combination was even better than using 26.20 kg of phosphorus alone, saving 6.55 kg of phosphorus without affecting the yield. This research shows that using the right bacteria and phosphorus levels can help soybean plants grow better and produce more seeds.
