In 2014, Iowa Learning Farms and Practical Farmers began a joint research effort to investigate the use of a highboy seeder to seed cover crops into standing corn and soybeans. The objective was to determine the effects of planting technique on the successful establishment of sole species and mixed species cover crops. Cover crop planting […]

The highboy seeding technique allows for an early seeding date that resulted in additional cover crop growth when compared to the drilled treatment that followed corn and soybean harvest. When comparing biomass of cover crop mixtures, the cereal rye and oats in the cover crop mixes made up the majority of the growth recorded. Corn and soybean yields tended to be unaffected by the cover crops.

 

RESEARCH REPORT

Cover crop planting season is coming for the northern Cornbelt! Many farmers are gearing up to aerial seed cover crops but how can we make sure we have green fields in the fall during harvest? Take some hints from cover cropper Nathan Anderson who farms near Cherokee, IA. In Nathan’s part of the state, sufficient […]

Using cover crops and side-dressing
nitrogen fertilizer is a common bundle
being investigated by Iowa farmers
concerned about soil health, water
quality and return on investment of
cover crops.
• Cooperators grew corn following a
winter rye cover crop and applied a low
and high rate of N fertilizer in a sidedress
application.
KEY FINDINGS
• In only one of six site-years did the
high side-dress N rate result in greater
corn yields.
• In most cases, by not applying the high
N rate the cooperators nearly recouped
the cost of establishing the cover crop
with savings in N fertilizer.
