In a study on maize plants, different fertilizer levels and micronutrients were tested in the soil to see how well the plants absorbed important nutrients like nitrogen, phosphorus, potassium, zinc, and manganese. The best results were seen when using a combination of NPK fertilizer, zinc, manganese, beneficial bacteria (Azotobacter), and phosphate-solubilizing bacteria (PSB). This mix led to higher uptake of nitrogen, phosphorus, potassium, zinc, and manganese by the maize plants, compared to when no fertilizers were used. The study took place over two years in a sandy loam soil and showed that this specific fertilizer combination made the maize plants absorb more nutrients, which could help increase crop yield in the future.
