Wayne Volkl, co-owner of SWJ Consulting, says no-tillers need to focus on fungi, the most efficient piece of the biological puzzle, when building their soil biology.
As nitrorgen (N) prices continue to soar, a panel of experts from the agriscience company Corteva recommend a few tips to help manage nitrogen carefully.
It’s not every day United States history mixes with microbes in the soil. But when the turf on the National Mall in Washington, D.C. was replaced, it offered scientists the opportunity to study changes in the soil underneath.
No-tillers who find Bt stalks are hanging around a little too often should take a hard look at the ‘soil animals’ in their fields — they’re in the driver’s seat.

Nematodes are often talked about in a quiet fearful voice. The image of the small microscopic worms can bring grown men to their knees. Unfortunately like many things in our world, a few? apples have ruined the entire bushel.
Unlike corn, wheat and most other row crops grown in North America, soybean is able to obtain its own nitrogen (N) through the process of N fixation. N fixation is achieved through an intricate biological relationship between soybean and a particular species of soil bacteria, Bradyrhizobium japonicum. The bacteria obtain sugars from soybean to use as their energy source, and soybean obtains N from the bacteria.
Dean Glenney’s 18 years of no-tilling attracted beneficial bacteria and increased his supply of ‘free’ fertilizer, creating record-breaking no-till corn yields in Ontario.
While Goss's wilt wasn't a significant problem in 2012, more intense storm systems this year could cause it to emerge as a problem for corn growers as the disease continues its movement eastward from the Great Plains. This disease can overwinter in the soil and crop debris for a few years, so if growers have had a problem before, it could be an issue again this year,says Scott Heuchelin, DuPont Pioneer research scientist, plant pathology.
When a farmer switches to no-till, they will probably find they can apply 60 to 80 fewer pounds of nitrogen in their cornfields, but still get the same yields.
