On average about one third of applied nitrogen is lost which costs the cotton industry $32 million each year. Fertiliser use efficiency can be improved through site-specific application of liquid nitrogen (N) in surface irrigation systems. A field-scale fertigation trial was conducted to assess: (1) the uniformity of distribution of the fertiliser applied; and (2) the agronomic performance of furrow fertigated crop based on fertiliser N recovery. The results reported in this study will aid the development of a set of practical recommendations concerning furrow fertigation in cotton to improve use efficiency of fertiliser N
