Formulated to provide a vegetative “push” when just a little extra nitrogen is required. This grade is used extensively in produce production as it will accelerate building of the plant frame, without sending the plant into extreme vegetative growth. Due to the amount of sugars inherent in the product, it is a high “energy” plant food. The trace mineral package is aggressive, so once again during the season these essential nutrients are supplemented. 28-16-7 is an important part of our vegetable/fruit program, and can be applied either through drip irrigation or as a foliar. If a mineral plant food such as 4-18-38 is being applied through the drip system, 28-16-7 is an excellent foliar choice, as the two products will “piggy back” on each other, thus providing dual benefits.
