ping is one way that a growing number of innovative growers
are doing this. Relay cropping is essentially a version of double
cropping, where the second crop is planted while the first crop
is still growing, rather than waiting until after harvest. Both
crops share a portion of the prime growing season, increasing
solar radiation and heat available to each and allowing two
crops in one year on more northern regions. Loran Steinlage
from West Union, IA is one of the leading proponents of this
movement and writes here about his experiences:
In 2013, I was getting very comfortable with innerseeding*
covers into V4 corn and started thinking of how these prin-
ciples could translate to the rest of our rotation? I wanted
to bring a small grain back to my rotation, but in my area
of high land rent I knew that wheat alone would not pay
the bills and we are too far north to double crop. As I was Over the years, we’ve learned what diversity of plant species
