MRTN Tool Helps No-Tillers Maximize Yield, Minimize N Costs

By Maclaren Krueger posted on November 3, 2023 | Posted in Nutrient Management

Predicting fertilizer needs and actual N uptake by crops can feel like guesswork, especially when trying to balance cost with net profit. However, when Dr. Emerson Nafziger’s data is accumulated and plotted, patterns start to emerge, which help farmers balance profit with optimum crop health.

It’s clear that the spring of 2018 is not going to be one that allows a very early start for field operations.

Insights into Grain Phosphorus and Potassium Numbers

Corn and soybean take up relatively large amounts of phosphorus (P) and potassium (K), and much of this P and K ends up in the grain that is taken off the field during harvest. In order to keep soil nutrient levels from dropping over time, the amounts removed need to be replaced by applying fertilizer or manure. In order to know how much nutrient a crop removes, we need to know how much there is in a bushel of harvested grain.

One of the speakers at the UI Agronomy Day at Urbana this past week was quoted as saying that corn producers had not planted enough plants this year to take advantage of the good growing conditions.

Corn Stover Removal And No-Till: A Balancing Act

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.

Is No-Till Still A Fad?

By Frank Lessiter posted on December 1, 2011 | Posted in No-Till Farming 101, Residue Management

One of the comments No-Till Farmer editors heard while pulling together material for last month’s 40th-anniversary issue was that some educators aren’t on board in promoting no-till. Such appears to be the case with Emerson Nafziger, who continues to devote considerable effort to the need for tillage

We’re Not There Yet, But 300-Bushel Corn Yields May Be Typical Just 20 Years From Now

By Frank Lessiter posted on February 1, 2010

David Hula captured top no-till yield honors in last fall’s National Corn Growers Association contest with a yield of 319.3 bushels per acre. While this Charles City, Va., no-tiller’s result was about double the current national average, 300 bushels is a yield some industry leaders are anticipating as being typical just 20 years from now.
