I was watch a seminar last night present by the University of Cornell and thought this tidbit might be useful to some of you who use cover crops in your plots.
Most non-woody legumes produce 2,000 lbs of dry matter per acre per 6" of growth. For each additional inch of growth add 150 lbs. If the area is not saturated with cover-crop, multiply the result by the % of ground covered.
How does CC relate to N:
Annual legume prior to flowering 3.5-4%N, flowering 3-3.5% N, after flowering <3%
So how much N are you adding? Dry matter x flowering stage % = N weight
