New Study Quantifies Large Increase in Corn Belt Maize Residue
Carbon inputs from maize residue in the Corn Belt increased almost 50% from 1980 to 2020, according to a new Iowa State-led study. The increase, driven by higher productivity and expanded corn acreage, has significant implications for crop management, farm economics and environmental sustainability across the region. Co-authors on the research included Alejo Ruiz, who recently earned his doctoral degree in crop production and physiology at Iowa State and is now a scientist with Corteva Agriscience, and Sotirios Archontoulis, agronomy. Their findings were recently published in the journal Communications Earth & Environment.

For Crop Breeders, Growth Curves Built on Drone Data Reveal Timing and Duration of Genetic Effects
Technology such as drones, robots and sensors make large-scale data collection throughout a growing season feasible, giving crop scientists the capability to discern the timing and duration of genetic effects, said Jianming Yu, agronomy. A research team led by Yu demonstrated the possibilities in a recent paper published in the Journal of Experimental Botany, which described a three-year study of sorghum at an Iowa State research farm near Boone.
Observations Show Trumpeter Swans Find Constructed Wetlands Appealing
Jayden Jech spent last summer taking measurements above, around and under water in constructed wetlands throughout Iowa – and he’s gearing up to do it again. Jech, a graduate student in wildlife ecology, looked for Trumpeter swan nests at more than 80 privately-owned constructed wetlands.

The Use of Commas – With Conjunctions
When a conjunction such as and, but or for links two clauses that could stand alone as separate sentences, use a comma before the conjunction in most cases: She was glad she had looked, for a man was approaching the house. As a rule of thumb, use a comma if the subject of each clause is expressly stated: We are visiting Washington, and we also plan a side trip to Williamsburg. But no comma when the subject of the two clauses is the same and is not repeated in the second: We are visiting Washington and plan to see the White House. (Associated Press Stylebook, 2024-2026 edition, pg. 397)

‘Lab-on-a-Drone’ Tests Remote Farm Waterways for Nitrate Levels
Iowa State researchers have developed a "lab-on-a-drone" that can fly to remote, marshy areas of farm fields and collect real-time measurements of nitrates. The resulting maps of nutrient concentrations could provide "an evaluation critical for both economic and environmental sustainability," according to the researchers.
Campus Message about Digital Accessibility
On April 20, the U.S. Department of Justice announced a one-year extension to the digital accessibility compliance deadline. The new deadline – April 26, 2027 – comes as the DOJ determined that the original timeline was not sufficient for the work required. This allows a shift from rapid remediation to steady, habit-building accessibility practices. It also means a PDF remediation solution will be available before the compliance deadline.
Barks at Parks Available During Prep Week
Students are invited to drop by the University Library's Upper Rotunda each afternoon during Prep Week between noon and 3 p.m. to destress by petting certified therapy dogs. The dogs are here today, Monday, May 4, through Friday, May 8.
