Iron Talk #1112 Seeding Cover Crops (Air Date 7-28-19)


D: With all the cover crop
going in this season as wheat comes off
and prevent plant acres dry out, today’s Iron Talk will
discuss some of the attention to detail required
to be successful. Avoiding fallow syndrome is one of
the reasons that you may want to plant a cover crop
right now. I agree that is a risk. Picking the right
cover crop or cover crop blend, though, is critical
because you can see fallow syndrome following crops
like radishes that don’t support mycorrizae fungi
that help bring phosphorus into the roots. For that
reason, we often recommend choosing a blend of cover
crops to support the diverse populations of soil microbes
and to serve multiple purposes. With blends,
though, seeding can be a challenge as seed sizes and
seeding rates may vary dramatically. There are two
solutions to this problem. First, you could seed the
ground twice. Put the smaller seeds in the drill
and seed the field. Then come back with larger seeds
in a second pass. A second solution could be to just
get a multi hopper air cart to go behind your drill so
you could keep each of the cover crops in their own
hoppers ensuring an even seeding across the field. A
new consideration in 2019 for cover crops is the fact
that prevent plant acres could potentially be grazed
or hayed after September 1st. Check with your local
officials to see exactly what the complete rules are
for your area as it will definitely impact which
cover crops you may consider. Yes, cover crops
can be a big help to the soil and to future crops. We
are big supporters of cover crops used after wheat
harvest and on prevent plant acres. If there’s not enough
time to grow an actual crop that can provide you income,
a cover crop is often the next best option to protect
your soils and to feed soil microbes. Careful attention,
though, is needed to spread the seed somewhat evenly, to
maximize benefits and eliminate potential
problems. That’s all for today’s Iron Talk and now,
back to the show.
