Soil gets tired. After years of supporting a rotating cast of crops, the soil’s nutrient supply is often exhausted. The tilling, turning, and planting also degrade the organic matter in the soil and its ability to stay hydrated.

This week we're joined by Dresden, Ontario farmer, Mark Richards, who has adopted and adapted precision farming strategies, including implement guidance, interseeding technology and data analysis on his 3,000-acre corn, soybeans, sugarbeet and wheat operation.

Brandon researchers spent 18 years combining three different input levels and crop rotations to study the impact on nutrients, soil quality, yield and implications for climate change.

Kansas State University Extension discusses technology to consider that could help take some guesswork out of determining optimum nitrogen application rates for winter wheat.

New research results from the University of Copenhagen's Department of Plant and Environmental Sciences report that weeds would have a tough time competing against crops such as corn, grains and soybeans if farmers were to alter their sowing patterns.

For growers who may have planted cover crops last fall, it will be very important to apply an effective burndown to these species in the coming weeks.

Cover crops can be excellent systems to capture excess nutrients and reduce the risk of erosion over the winter months.

Some producers are taking advantage of frozen ground conditions to apply nitrogen to wheat fields or manure to corn fields.

The unpredictable climate often provides enough moisture to maintain a healthy crop throughout the growing season, but also challenges the Nixons to plan accordingly with fertility and residue-management strategies so they can be ready to plant in a timely manner.

An agricultural dragnet has found no cases of unapproved genetically engineered wheat outside of a 123-acre field in Oregon after two months of an ongoing investigation, the USDA said recently. The discovery of the wheat, not approved for cultivation anywhere in the world, shook the global market when it was announced on May 29. Some U.S. customers in Asia and Europe halted purchases or said they would test incoming wheat shipments for biotech grain.
