Study: High nitrogen rates increase micronutrient uptake

A study done by Purdue University shows that high-yielding, modern corn hybrids take up not only more nitrogen from soil but more micronutrients such as zinc, iron, manganese and copper. Nitrogen fertilizer rates also influence how much of these nutrients are stored in the grain at harvest. Growers may need to use fertilisers to meet the increased micronutrient requirements of hybrid corn in high-yield systems, especially if soil nutrient levels are too low. “This study raises the questi
