The study looked at how different plant nutrient sources affect soybean growth and soil fertility. They tested eight treatments, including adding zinc, boron, iron, and other nutrients to the soil. The results showed that the treatment with molybdenum (T4) gave the highest seed yield and profits. This treatment also led to the highest uptake of nutrients by the plants. Another treatment with organic fertilizer (T8) improved soil quality by increasing organic carbon and essential nutrients. Overall, adding specific nutrients to the soil can increase soybean productivity and improve soil health.
