3/16/95 JBC CORE buckwheat 30 bushel yield, data from Farmer's Bul. 1835, Growing Buckwheat,
CPIDS, & Martin and Leonard '49, pp.862-870. REV 61801 DTL
Cloned mustard from ARS and changed planting rate, yield, and harvest index. 5/3/07 MAS
Changed the cover to mass value to match Fosters finest stem curve, Small Grain and Alfalfa. Reference pg. 179 Ag Handbook 703.
No crop has a larger number (finer stems) than .000586. This matches RUSLE2. MAS 12-21-10
Changed the percenage of the flowering mass harvested from 0.4 to 0.8 as Fred Fox suggested to correct
an error message. Moved the days of growth from 90 to 70 based on a paper Buckwheat,
Alternative Fiedl Crops Manual, University of Wisconsin Ext. E.S. Oplinger Dept of Ag. Nov 1989.
He said the crop will grow in 10 to 12 weeks (70 to 84 days). Moved the internal biomass adjustment
factor from 25 to 40 to reduce the External factor down from the 3.9 on a run in Clay Co. MN using a
CMZ 1 Buckwheat template. After adjustment it is between 2 and 3 now. 12-28-10 MAS
