Info on "Economic Outlook"

I write on behalf of an organic farm in Ukraine.
Thank you for the very useful information's you made available on the article "Economic outlook for herbs and spices year 2000". Can I ask you a few questions about it?
1. I guess the units of measure are always $, lb and acre. So, for example, yields are always in lb/acre and prices in $/lb. Is it correct?
2. The top 53 herbs are so according to sold quantities, or value? 3. In 'TABLE I: Estimated Crop Yields' the last four figures are the dry-weight yields for the 1st, 2nd, 3rd and 4th year (correct?). What is the second figure (also yield): an average?
We also enjoyed your book: "The potential of herbs as a cash crop"

Yes, yields are always in pounds per acre, and prices are always in dollars per pound (US).
No, the top 53 herbs are not the top herbs sold, but organized from the original order Conrad Richter's list came to me. I kept his order thinking this might be significant to his own organization of information. Spices are much larger volumes in sales, to include oil and other forms that the crop might be sold.
Yes, the last four columns are first, second, third and forth year yields per acre (in dollars). The second set of numbers under costs per acre are those for second year production costs. Some perennials are less to keep weeded than to establish.
Thank you for your nice comments regarding my writing in herbs. I write in other areas and have many other book titles available. Please visit my website for more information at www.nwbotanicals.org.
