Thanks Harry, I feel quite flattered. It seems you place quite a bit of faith in my dabbling. With regards to costs, it all comes down to variable costs per hectare. With regard to this, variable costs are cost of fertiliser, cost of chemical, cost of fuel, cost of seed, depreciation on plant, windrowing, wages, return on capital investment and of course, yield. These are different for every farmer, but for myself, the variable costs of growing Canola are somewhere in the vicinity of $240.00/ha and I would assume a yield of 2 tonne/ha..so I guess that gives us a figure of $120 per tonne. Again, to come up with a cost per litre of oil extracted, you need to add in capital investment of plant and infrastructure, electricity, wages, etc. With regards to the most suitable oil, if you could give me an idea of a "dream" FA composition, I may be able to get my hands on some information that may steer us toward an "ideal" cultivar. regards Steven
