Penn State research may aid dairy farmers | News, Sports, Jobs

May 10, 2021
UNIVERSITY PARK For corn, using dairy manure and legume cover crops in crop rotations can reduce the need for inorganic nitrogen fertilizer and protect water quality, but these practices also can contribute to emissions of nitrous oxide a potent greenhouse gas.
That is the conclusion of Penn State researchers, who measured nitrous oxide emissions from the corn phases of two crop rotations a corn-soybean rotation and a dairy forage rotation under three different management regimens. The results of the study offer clues about how dairy farmers might reduce the amount of nitrogen fertilizer they apply to corn crops, saving money and contributing less to climate change. ....

Short on forage? Have a plan for green-up

TRY SOME OATS: A planting of spring forage oats could help bridge the gap if you think you’ll be short on forage later this year. But get it in early, as soon as the ground is dry enough.
If you can spare some acres, oats can be a good way to add forage.
If you got a late start planting your winter annuals, or you got some winterkill and are worried about available forage this spring, now’s the time to shore up your spring green-up plan.
“It’s a tight fit. You ve got to be on the ball with it,” said Dave Wilson, a Penn State agronomy Extension educator, during a recent webinar on dairy double cropping. ....
