Replenishing Nutrients After Harvest

After a harvest of higher than expected yields for both corn and soybeans, P and K deficiencies tend to appear. Caused by the high nutrient withdrawals from those big yields, DuPont Pioneer Field Agronomist Jonah Johnson said monitoring those nutrient numbers is important.

Sometimes we get caught up if we apply in a two-year pattern and don’t replenish the ‘fuel for the fire;’ we may actually become deficient in the soil. I’m starting to notice a lot of P and K deficiencies, especially in potash, Johnson said…Hear more

2018 Tillage Plans

If you are creating a 2018 tillage plan and considering ridge till, sharp till or no till, T.C. Hoffman with DuPont Pioneer said a fall burndown of weeds will keep fields clean so you can accomplish these tasks.

“This allows you to get ahead of it before the weeds get a chance to really take hold and be a lot harder to deal with in the spring,” Hoffman said…Hear more

DuPont Scientist Receives Franklin Institute Science Prize

DuPont Senior Scientist Philippe Horvath has been awarded the Franklin Institute’s prestigious 2018 Bower Award and Prize for Achievement in Science. Horvath will be honored for groundbreaking research on CRISPR-Cas during a ceremony in April 2018.

DuPont is a leader in the CRISPR area, with about 60 patents and applications and more than 30 published scientific articles and book chapters. DuPont Pioneer applies CRISPR-Cas as an advanced plant breeding tool as a targeted way to improve plants and help farmers produce more and better food, with fewer resources…Read more

Corn Residue Breakdown Myths

Fact or fiction? Bt hybrids break down faster if additional nitrogen is applied. It’s fiction, according to a three-year tillage and residue field and laboratory trial in Ames, Iowa. Researchers found no differences in corn residue breakdown because of tillage or type of residue…Read more about corn residue myths

Understanding Forage Digestibility

When selecting corn hybrids, dairy producers often consider many factors of nutritional quality for dairy rations. Today’s corn silage hybrids offer high yield potential, but can vary substantially in nutritional quality depending on genetics or environmental factors.

While small differences in fiber digestibility exist among conventional silage hybrids, the biggest influencer is the plant’s growing environment during the vegetative stage…Read more
