Hi Andrew No, you're reading it wrong - it's 1000 kg of oil, not of seed: 1000 kg of oil, 1190 litres of oil. It's not totally accurate, I've used a benchmark figure for the weights of oils, though they don't all weigh the same. But these are just approximations and can't be anything else, when you consider how greatly crop yields can vary. They're most useful as comparative figures between crops. Did you figure you'd only get 145 kg of corn from a hectare? :-) Best wishes Keith Addison Journey to Forever Handmade Projects Tokyo http://journeytoforever.org/ Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html To unsubscribe, send an email to: [EMAIL PROTECTED]
