The Difference between Maximum Profit and Maximum Production

 

Nitrogen fertilizer (N) is commonly used as a production input to increase crop yields. It is included as one of the six Testing Ag Performance Solutions (UNL TAPS) program decision choices and contributes much to productivity as well as costs. Its use, however, is not without controversy. The over-application of N gets into the groundwater and nearby waterways becoming a pollutant. Excessive use does little or nothing to increase revenue but can inflate costs, thereby reducing profit.

 

For these reasons and others, using the right amount of N has become a popular and important topic among those that use and/or study it. The main problem in using this nutrient is determining the right amount to use and apply. Like many natural processes, at some usage level N exhibits a diminishing marginal effect that is, at a specific level of use the next added unit returns less than the previously applied unit.

 

 

In this week's Cornhusker Economics Nebraska Extension Agricultural Economist Matt Stockton looks at corn yield response to N and provides an economic analysis of N application. Using data from the UNL TAPS trials and considering three factors — the biological relationship of N to corn grain yield, N costs, and the value of the grain being sold  — Stockton analyzes the data and explores how to determine the economically optimal quantity of N for individual fields.

 

Video: USDA Feb Crop Report a WIN for Soybeans + 1 Year Trade Truce Extension

USDA took Trumps comments that China would buy more U.S. soybeans seriously and headline news that the U.S./China trade truce would be extended when Trump/Xi meet in the first week of April was a BIG WIN for soybeans this week! 2026 “Mini” U.S. ethanol boom thanks to 45Z + China’s ban of phosphates from Feb. – August of 2026 will not help lower fertilizer prices anytime soon! 30 mmt of Chinese corn harvest is of poor quality and maybe a technical breakout in wheat futures.

*Apologies! Where we talk about the latest CFTC update as of 10th Feb 2026, managed money funds covered their net short position in canola to the tune of +42,746 week-on-week to flip to net long 145 contracts and not (as we mistakenly said) +90,009 wk/wk to 47,408.
