[QUOTE="Gong Farmer, post: 7954612, member: 4607"] The NT26 was an empirical ADAS trial trying to investigate extremes. All N was applied in one dose in May and plots covered in plastic to collect any gases emitted. This of course had a greenhouse effect and made sure there were gases emitted. (60% loss from urea, 10% from AN I think). However fertiliser manufacturers have milked this to extremes, not surprisingly. Anyone who applies all their N in one dose in May and then covers the crop should not use urea, therefore. (I think Brisel is referring to the NIAB TAG database which gives very different views). I have also seen signs of ADAS going the way of a lot of science these days, most work funded by manufacturers and you won't get repeat funding if you get the wrong findings. [/QUOTE]
