CFQ: Integrated Management Necessary for 300-Bushel Corn
“Because of the environmental complexity of nitrogen and the loss factors associated with it, data shows that it can be very beneficial to split the nitrogen application,” Freeman noted, “to continually provide the nitrogen as close to when there are high demand time frames for it by the corn plant.”
To achieve the highest yields, Freeman suggested, “We see a tremendous response to soil-applied sulfur when we start pushing the yields.” As for other micronutrients, he said, “Zinc is a really important nutrient for corn.” Then he noted, “People are spending more time addressing boron needs in high yield corn.”
Addressing high yield corn goals is why Mosaic began offering a premium fertilizer in its MicroEssentials SZ. The phosphorus, “season-long” sulfur and zinc are combined into one granule for balanced crop nutrition.
But the ending comment by both company specialists was to advise corn growers to lean on their local agronomists (seed, ag retailer or private) for recommendations to fine-tune any high-yield program.
