Looks like a lawn care product for heavily irrigated turf. But any foodplot would benefit from a foliar application of that product with the N, S, Fe and Mn. Just fill up your spray tank with water and add the product, anytime you want to give the plot a boost of nutrients. Keep in mind, it only has 29.8 lbs of a 13% N liquid, or 3.8 lbs of Nitrogen. ;) The real value is in the foliar application of micro nutrients S, Fe, and Mn, especially if your plot needs a short term nutrient fix.
