years of on-farm studies in southern Saskatchewan (with only
5-6 inches rainfall) produced on average 80-100 lbs. N/acre,
with over 200 lbs. produced in a research test plot.
N2 from the air is fixed by Rhizobium bacteria inside
root nodules in the top foot of soil beginning about two weeks after
and reaching maximum activity between early and full bloom.
80% of the N is contained in aboveground growth, with the remaining
20% found below ground.
optimum growing conditions, as much as 5 lbs of N can be
fixed per day. Plant growth usually ranges from 18-36 inches
high with plants in full bloom by about 60 days.
matter production between 2000-4000 lbs/acre is common with fields
exceeding 6300 lbs/acre
in a wet year in Canada.
85% of this nitrogen is available to the following crop. AC Greenfix
has an indeterminate growth pattern
and will continue to flower and grow as long as there is
adequate moisture and temperature.
