Other trial notes |
This trial has demonstrated that although all soil zones have responded positively to applied nitrogen, the level of responsiveness is highly variable. When considering nitrogen management decisions in the future for this field there are a number of other factors which should be considered. These include timing, topography (which is likely to influence water behaviour, evaporation losses and frost), a better understanding of subsoil constraints, and most import |
