I've had 25 years to refine my no-till system, but I’m nowhere near settling into a comfortable groove. My philosophy is to keep pushing my system to get more yield, use my inputs more efficiently and make life easier for myself and my son, Chris, who farms with me.
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.
Pennsylvania no-tiller Dean James is focusing on secondary macronutrients, micronutrients and precision fertilizer applications to bring yields to the next level.
Plugging the lowest leak in the fertility barrel to boost yields and cut waste is the goal Dean James set for the 1,250-acre farm he manages. But achieving that goal requires creating a detailed fertility picture.
Had Dave Nielsen simply accepted the early tales of frustration he heard, no-till might not have become the dominant practice on his dryland farm. Instead, he decided to place more trust in early no-till innovators and university experts in his area.
For successful results in strip-till, fertilizer needs to be placed in a zone where the roots and seedlings of corn can readily access plant-food nutrients.

Increasing corn yield and harvest of cornstalks for feed, bedding or bioenergy production are generating numerous questions about phosphorus and potassium concentrations in cornstalks and removal.
Agronomist says a mixture of 28%, Thio-Sul, humates, sugar and water can help digest today’s tough corn stalks for better corn yields the following year.
Corn residue has its good and bad points. It’s not so good if it interferes with no-till seed placement or crop emergence, but it’s a great source of food for soil biological activity and contains valuable nutrients for the next year’s crop.

On this episode of Conservation Ag Update, brought to you by Martin Industries, Vincennes, Ind., no-tiller Ray McCormick explains why it’s going to be tough to “not lose a lot of money this year” on corn. Plus, we ask our readers, “On a scale of 1-10, how concerned are you about drought this year?” Hear why some farmers are worried, and why others aren’t very worried at all.
Needham Ag understands the role of technology in making better use of limited resources within a specific environment by drawing on a wealth of global experience to overcome the challenges facing today's farmers, manufacturers and dealers.
