     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
