Would be interested to hear peoples opinions on whether they think GM will increase the sustainaility of agriculture, not just nationally but internationally, and also whether Precision farming will increase the sustaianability? Thanks

Precision Farming is definately the way forward as its more accurate than anything we have been use to. Nobody can say it isn't because even if its just a steering system it means your being more accurate but to go the whole hog into it with yield mapping and soil sampling and the rest is just far to expensive when selling crops at bad prices like they are at the moment.
