Abstract

•Topdressing urea in green-harvested sugarcane results in high ammonia (NH3) losses.•High amounts of crop residues and tropical conditions reduce the efficiency of NBPT.•Doubling current NBPT concentration in urea (530mgkg−1) reduces NH3 losses from urea.•NBPT concentrations ≫>1000mgkg−1 urea do not grant better results.
