Tplay; I want to make sure you know the reason I said "lets try this again" was because I kept typing responses and either getting cut off or having power failures. Your questions were good, you had me digging out my old text books but I hope it helped.

Just remamber that any numbers that you get will be based on a farmer getting the best return for his money if he harvested and sold the crop. You can fertilize to higher rates to get more yield if you don't mind spending the money.
