To maximize above-ground profits, Ed Winkle maintains that no-tillers must be attuned to the basics of what’s happening under the ground. The certified crop adviser with HyMark Consulting in Blanchester, Ohio, says a proper balance of oxygen, hydrogen and carbon is critical to harvesting top no-till yields.

While it's not likely to be a paying proposition in your no-till fields, gardeners are being encouraged to purchase earthworm castings to improve the productivity of their soils. Marketing materials for these casting products definitely show the correlation as to why increased earthworm numbers in your no-tilled fields help boost yields and protect the environment.

Q: How many earthworms do you need in no-tilled fields? A: To gain the benefits of a good earthworm population with no-till, you need 8 to 10 worms per square foot of soil 6 to 8 inches deep.

Conservation farming is revolutionizing agriculture through the adoption of new ideas, technology and practices. Direct seeding (no-tilling) is just one of these new practices that is reforming the way that we farm.

Known as the glue that holds humus to soil particles, a gooey substance called glomalin plays a critical role in the success of your no-till program.

Monsanto has received full U.S. regulatory clearance for the first biotech corn designed to control corn rootworm. The company announced in late February that both the Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) has cleared YieldGard Rootworm for use in corn hybrids for resistance to this insect. Licensing the technology to other seed companies means a number of corn hybrids containing this technology will be available for no-tilling this spring.

If next spring’s planting season turns wet, Randall Reeder says no-tillers who use controlled traffic may be ahead of their neighbors. The Ohio State University agricultural engineer says it might let you no-till quicker despite wet conditions that normally delay planting.
