Subject: RE: 60" corn pics



My main rationale for terminating the CCs in some of our solar corridors was to help the corn finish well by:
1) eliminating competition for soil resources 2) increasing light penetration 3) increasing N availability

I am also interested in testing options for establishing cool season CCs and controlling some weeds.

In our larger solar corridor experiment this season with 2 out of 3 rows planted to corn, we have 2 solar corridor treatments. We chopped the forage soybeans in one treatment and left the forage soybeans in the other. All other management practices were the same so we should get some good data on the impact of chopping vs. letting the beans grow.

BTW My preferred solar corridor system is the simplest system - planting 1 or more legume species while planting corn and then managing the field just like 30" corn (including letting the legume grow until killing frost or corn harvest) but I also need to explore options for minimizing the yield hit we observed in solar corridor corn in 2018 and 2019.
