The purpose of the Nutrient Dense Spray (NDS) trial was to evaluate the impact of nutrient dense foliar sprays on perennial forage yield, quality, and fatty acid concentrations. The nutrient spray program was developed by Advancing Eco-Agriculture (Middlefield, OH) and consisted of five foliar sprays specifically recommended for the farms participating in this study. The recommended foliar applications were evaluated over 3 growing seasons. In the third year of the study, a sixth foliar spray, ‘Sea Shield’ was added to the treatments. The recommended spray program included applications of Rejuvenate in the early spring and late fall, and a combination of PhotoMag, Phosphorus, Potassium, MicroPak, and Sea Shield applied in the spring and after each harvest of hay or graze (Table 1). This study was conducted based on farmer interest in enhancing nutrient density of forages through foliar sprays and was funded by the Lattner Family Foundation.
