[QUOTE="Goldilocks, post: 7215182, member: 2216"] Maybe i wasnt clear . When i say reduce N inputs i am meaning synthetic N. Obviously all natural N sources are good and even synthetic N up to a point becuase you are using it to grow bigger , higher yielding crops that are photosynthesising more . Trick is to use it at a level that does not become wasteful and environmentally damaging , hence need to redraw N dose response cuves to reflect environmental issues and arrive at a new sustainable optimum.e.g. having a stab to put numbers on how about moving down from a rtypical UK rate of 220 kg/ha on wheat to somewhere nearer 140 -160 kg/ha ???????? Also need to work on N use efficiency to try to max. that out. [/QUOTE]
