The Impact of Nutrisphere®

Research into Nutrisphere® indicates promising results within increasing yield growth, maximum yield and plant biomass.

Research conducted by Heiniger, Smith and Wiatrak of North Carolina State University and Clemson University, respectively, to understand the impact of the polymer coating Nutrisphere™ in increasing nitrogen use efficiency and corn yield reveals interesting results.

Currently, it is estimated that 50% to 60% of the N applied fertiliser is actually utilised by the crop with the remaining N lost through leaching or denitrification. A three year study was conducted at eight locations in North Carolina to examine the impact of Nutrisphere™ on corn yield, optimum N rate, maximum yield, tissue N concentration, plant biomass and N uptake.

With less than ideal growing conditions in this study, nevertheless, the overall trend indicated that Nutrisphere™ increased yield compared to the use of Urea Ammonium Nitrate (UAN) alone with a significant (p<0.10) yield increase.

While Nutrisphere™ only reduced optimum N rate in two trials, there was a consistent increase in maximum potential yield across trials. Moreover, plant analysis also found that Nutrisphere™ increased biomass at one location.
