I recently spoke at the Southwestern Wisconsin No-Till Field Day, where we've had an extremely wet spring. One recent storm in this area dumped more than 10 inches of rain in 1 day.
Concerns about long-term shifts in climate patterns have led scientists to measure soil organic carbon (SOC) in agricultural landscapes and to develop methods to evaluate how changes in tillage practices affect atmospheric carbon sequestration.
A 24-hour rapid test could help farmers unlock the secret to fertility potential in their soils and make more informed decisions about fertilizer applications.
A new method of soil testing that measures the drying and rehydration cycles in farm ground could help no-tillers use fertilizer more efficiently and even choose the best cover crops to seed ahead of the next crop.
When we're in a drought, farmers don't think about planting cover crops, but they should consider it, says Kris Nichols, research soil microbiologist with the USDA Agriculture Research Service, Mandan, N.D.
No-tillers that follow guidelines can remove some stover from continuous-corn fields and still warm up soils, improve nitrogen efficiency and retain organic matter.
No-tillers growing continuous corn often face a dilemma when residue piles up in their fields after harvest, leaving a mat that can keep soils cold and wet and make planting difficult.
Cover crops are the turbocharger of a no-till operation, but scientists and growers alike are still researching and fine-tuning how covers fit into crop rotations.

To preserve long-term carbon balances and soil productivity, the goal of maintaining 2,500 to 3,000 pounds of organic matter, on average, after each crop should be the goal.
Keeping the soil permanently covered is the best way to increase profits in farming no matter where a producer lives or what kind of soil his fields have, says Juca Sa from Ponta Grossa, Brazil.
