Ripe as a Roadkill Raccoon

Posted on June 3rd, 2020

Hydrologists classify watersheds using a hierarchical system that “nests” watersheds within one another, an idea that resembles a broad oak tree with the trunk being a large river such as the Mississippi and the countless branches its numerous tributaries. Each watershed or branch is given a number—a Hydrologic Unit Code (HUC) with the larger branches […]

China journal

Posted on April 15th, 2020

Note: Four years ago today (4/15), State Geologist Keith Schilling and I traveled to China at the invitation of Keith’s Ph.D. advisor at the University of Iowa, You-Kuan Zhang. You-Kuan had recently left UI to become a faculty member at Shenzhen University near Hong Kong. We went there with the intention of deploying a nitrate […]

“I’m not a scientist”

Posted on March 31st, 2020

You may have noticed that we have few trained scientists occupying elected positions in the United States. In the 115th Congress (1), members include one chemist, one physicist and one microbiologist, all in the house. By comparison there are 218 attorneys (including 47 former prosecutors and 15 judges), 101 teachers, 26 farmers, 8 ordained ministers, […]

Hair of the Dog

Dr. Silvia Secchi wrote most of this; I added a dash of bitters here and there. The post expands on the interview Dr. Secchi gave to National Public Radio’s All Things Considered, which can be found here: https://www.npr.org/2020/03/13/815546846/the-biofuel-requirement-of-american-gasoline-hits-a-roadblock The Iowa congressional delegation and many agricultural economists have been arguing over the small refineries exemption, which reduces the […]

The ethics of a pig

Posted on March 4th, 2020

Note: some of these ideas came from Smith Fellow Dr. Bonnie McGill. Writing with a great nom de plume, O. Henry1 (William S. Porter) may have been the G.O.A.T. short story writer and his best one was the ironic comedy, The Gift of the Magi. O. Henry also wrote one titled The Ethics of Pig, […]

They break it, you buy it

Posted on February 25th, 2020

Last Thursday (2/20/20) the Iowa Soybean Association (ISA) released the results of a study1 showing Iowa farmers could save up to $99 million per year by better aligning their fertilizer amounts with corn requirements. Among other things, their data show that surveyed farmers were applying about 34 pounds per acre more nitrogen fertilizer than ISU […]

Fool Me Once….

Posted on February 12th, 2020

This morning I read for the second time in two years that our state’s agriculture department is “just getting started” on addressing Iowa’s problems with nutrient pollution (1,2). As my favorite 1960s TV star Jerry Mathers would say, “gee that’s swell”, since this pollution has been around since Leave it to Beaver was still a […]

Notes: Some of these words and ideas came from the head of Dr. Silvia Secchi. Featured image credit: Rigzone. Nexus is one of those trendy words that can help a frequent user sound more relevant. It’s so much sexier (it has an “x”, after all) than mundane synonyms like connection, and let’s face it, good […]

Free Iowa Now

Posted on January 23rd, 2020

The California-sized Black Sea is bordered by Russia, Ukraine, Bulgaria, Romania, Georgia and Turkey. It receives freshwater from several major European Rivers (especially the Danube) but Mediterranean Sea saltwater also intrudes through a hydrological connection known as the Bosphorus. Thus, Black Sea water is saltier than a lake but fresher than the ocean, producing a […]

I spoke with a colleague this morning who had returned from a holiday break spent at her rural Iowa childhood home. While we were each cooking up the usual post-holiday small talk, she related to me some of her recent conversations with farmer relatives that included this idea: There is not a problem with Iowa’s […]
