Key Technical Points for Safe Pesticide Use in High-Oil Soybean Production
Although soybean can fix free nitrogen from the atmosphere through root nodules, this accounts for only 30%-50% of its requirement, and the rest must still be supplied by the soil. Therefore, applying nitrogen fertilizer to soybean can strengthen stems and increase branching, expand leaf area, enhance photosynthesis, and improve stress resistance. In plots with poor soil fertility, topdressing should be carried out at the seedling stage...
