Reduce the potential for loss of your nitrogen (N) investment to leaching, volatilization, and denitrification.
We are driven by the conviction that fertilizer will play a critical role in meeting increased global demand for food in the future, and that fertilizer must be used safely, effectively and efficiently. ESN was developed with the 4R’s of Nutrient Stewardship in mind—Use the Right nutrient source at the Right rate, at the Right time, and in the Right place. ESN should be a key part of any grower’s best management practices.
ESN is a water-soluble nitrogen within a flexible polymer coating. The polymer coating allows moisture to pass through and dissolve the N granule within. Then the N solution releases as soil temperatures increase. Ensuring that the N rate matches crop demand. ESN is the right source for many N applications because it can improve N use efficiency and simplify decisions on rate, timing, and placement.
To maximize crop yield, the right rate of each nutrient needs to be applied. ESN is 44 percent N. The best recommended practice is to apply the optimal amount of N needed to maximize profits, which typically occur at an N rate slightly below that needed for maximum yield. ESN’s polymer coating protects N from loss to the environment and therefore the N applied will be available to the crop when it needs it. Reducing N loss by using ESN results in more predictable yields and optimum rates.
Nutrients are required at specific times in the growing cycle of the crop. When these nutrients are applied and available is critical to maximizing profits. Because ESN protects N from loss, the grower has the flexibility to apply N over a much wider window than with conventional fertilizers. ESN can be applied from before planting to side-dress, and even in the fall in some geographies. Because ESN releases N solution throughout the season, it ensures the needed N will be available at the right time, when the crop requires it.
Placement of nutrients is critical to crop development, but some nutrients can be toxic to the crop if placed too close as it emerges. For those growers who apply N at planting, studies have shown ESN can be applied at up to three times the safe rate of urea and still be safe for the crop. Some N sources may be prone to specific loss mechanisms with certain placements and require special considerations to prevent these losses. For example, surface application of urea may be particularly prone to volatilization. Performance of N placements with conventional fertilizers therefore have a greater risk of loss when compared to ESN’s built-in loss prevention technology.
