Simulation of Commercial Aerial Application of Urea

Contents Menu Helicopter loading fertilizer

The objectives of this project were to:

  • demonstrate the biological response of native forage species to an operational, aerial application of nitrogenous fertilizer
  • based on the biological data, provide an economic assessment of the feasibility of large scale aerial fertilization
  • demonstrate range fertilization to beef producers and interested resource agency personnel by way of field days and inspection tours.
