2018 Spring Planting

We applied a burn-down herbicide application on May 8 to terminate the cover crops and control other weeds. On May 9 we planted a group 2.7 soybean. This included planting with a drill into standing cereal rye, wheat and annual ryegrass. This has become a fairly standard practice among experienced cover croppers. Sometimes the cover crops are controlled after planting with an early post application. The standing cover crops do not usually created a problem planting into – you just need to make sure your planter is set up correctly. As the cover decomposes it creates a mulch layer which can be a big help keeping soils cooler and retaining moisture during hot, dry years.

Keep in mind that with corn you can have a problem with a high carbon to nitrogen ratio creating a deficiency situation early in the growing season, particularly with cereal rye, but this is not an issue with soybeans.

Early May was a very dry period for this part of Indiana. I took some pictures on May 25 (not included). The beans were up but barely and I was a little worried about complete termination. We received some rain last week, about 1.5″, and things changed completely with good elimination of the cover crops and what looks like a nice stand of soybeans.

Hopefully with the shorter season beans and an early May planting we’ll be able to get our fall covers in place in a more timely manner than we’ve been able to do the last 2 years. For the start of the growing season things look very good.

Soybeans planted into the Annual Ryegrass/Hairy Vetch/Crimson Clover/Rape strip. The growth is from annual ryegrass. Use caution with this one – once annual ryegrass goes to seed it can present a problem down the road. Picture taken June 4.
