Maximizing return on corn nitrogen investments

Though uncertainty with spring weather may always exist, resources are available to reduce grower uncertainty when selecting corn nitrogen (N) rate applications.


Soybeans and nitrogen fertilizer, again

In April 2014, Emerson Nafziger, University of Illinos, wrote on the topic on N fertilizer on soybeans, reporting that research at the University of Illinois has rarely shown a benefit in yield to applying N fertilizer during the middle part of the season. But it seems that some people, perhaps reacting to testimonials of high yields after using N fertilizer in the high-yield conditions of 2014 remain convinced that adding N fertilizer “makes high yields higher.”


Applying nitrogen fertilizer to wheat in early spring

Early spring is the time wheat growers implement nitrogen (N) fertilization strategies. This means estimating the amount of N needed and estimating how much of the N might be lost due to excessive rainfall and saturated soils.


MSU and Noble Foundation to coordinate N fixation research

A new federal grant will establish Montana State University and the Noble Foundation in Ardmore, Okla., as global hubs for integrating research activities on the supply and utilization of nitrogen by plants.


Cotton nutrition and fertilization

A major factor affecting both cotton yield and quality is the availability of adequate and balanced nutrition. Soil nutrients are taken up by cotton in direct proportion to growth and temperature, with total nutrient uptake for nitrogen (N), phosphorus (P) and potassium (K) tracking cumulative heat units.
