rate, which will reduce your costs
and plant competition.
For example, when sorghum
sudangrass (aka Sudex) was part of
a summer annual cover crop mix, it
grew fast in warm weather, tillered,
and was often too competitive with
other plants. This is one example
discussed in Bybee-Finley's et al.
article (2022). Also, if a legume seed
cost is too high, you may want to
reduce its seed rate, but note that
legumes are often less competitive
when there is adequate nitrogen in
the soil because legumes grow best
in lower nitrogen soil.
Some plants are more competitive
when grown as a sole crop
(intraspecific competition) but
less competitive when grown in a
mixture of species (interspecific
competition), such as pearl millet.
This species " plays well with others "
and can fill in the gaps.
Plant growth rates
Choose cover crops species that
can grow well in your environment
and at the time of year they are
planted. Selecting species with
different physical traits often
provides different functions. For
example, some cover crops (such as
Daikon radish) produce a tap root and
help with soil drainage. Plants with
fibrous roots such as cereal rye will
help reduce erosion. When grown
together, they can fill the space
collectively, above and below ground.
This aspect is a key reason to grow
mixes, as they increase soil cover
and weed competition in addition to
providing their own contributions.
Strive to adjust the rate for each
species to obtain a more even
stand and get the most out of your
investment. This approach will
increase effectiveness of the mix and
may even reduce seed cost. Threeand
four-way mixes are the most
practical number of species to include
and can address several goals in
one season. This has been shown in
several field research studies.
Incorporating these considerations
when choosing seed rate and seed
mixes may not produce a perfect cover
crop, but be a great improvement
over using one-crop species and
single seed-planting rate.
