Managing Micronutrients for Improving Soil Fertility, Health, and Soybean Yield
Micronutrients such as Fe, B, Mn, Zn, Cu, Mo, Cl, and Ni are essential for plant functions and soil fertility. This review synthesized findings on soybean responses to micronutrient application across the U.S. Midwest. While yield responses were generally positive, results varied depending on soil type, organic matter, moisture, and temperature. Both soil and foliar applications were reviewed. Deficiencies have become more common with the adoption of high-yield cultivars and extensive macronutrient use. The study emphasizes the importance of improving micronutrient management strategies and promoting soil organic matter to sustain fertility and yield.
