Objetivo General

Increase pasture Nitrogen Use Efficiency (NUE) by using a foliar N enhanced formulation, bypassing N soil cycling.

Objetivos Específicos

  • Quantify NUE in plants after using different N fertilizers formulations.
  • Quantify N fate and partitioning in plants when using a foliar N enhanced formulation under controlled conditions.
  • Evaluate soil and plant interactions under field conditions when using foliar N enhanced formulations.
