I have written some things about manure lately (link, link, link, link). If you were able to make it to the end of those essays, you learned:

· We have a lot of livestock animals in Iowa

· These animals produce a lot of waste

· This waste is used to fertilize crops

· Manure is a good fertilizer

· Sales of commercial fertilizer are not affected very much by the availability of manure

The Landscape of Capitalism by former University of Iowa professor Robert F. Sayre (1933-2014) is an excellent short history of Iowa agriculture. I read Sayre’s essay many years ago and had all but forgotten it, but it was restored to my memory recently by a conversation I had with an ag drainage engineer.

Stop saying we all want clean water

If you have followed water quality issues in Iowa, you’ve probably heard or read the phrase, “We all want clean water.” If so, in all likelihood it came from someone of stature or someone knowledgeable about water quality issues.

A while back I had the idea to shake the Google tree and see what fruit fell to the ground when I entered the phrase “we all want clean water.” It turns out one of our politicians has been quoted saying this so many times that I had a hard time figuring out who else had said it, so I started plucking names out of my head and attaching them to the phrase.

What resulted was an impressive list, a veritable who’s who of Iowa politics and agriculture.

You might recall a recent post assessed the amount of public land Iowa has relative to other states. Iowa is 8th-lowest of the states in the total amount of public land and 3rd-lowest in the percentage of our land area that is in public hands. This made me wonder about water, specifically, how much water we have relative to other states.

Many have written how earth’s species are undergoing a mass extinction right now, the sixth such event in the planet’s history. These writers include Elizabeth Kolbert and the famous biologist Edward O. Wilson. Extinctions are occurring now at a faster pace than any time since 65 million years ago, when earth’s collision with a 7-mile wide asteroid caused the 5th great extinction, wiping out 70 percent of all species.

One species that did survive the fifth extinction was the Pallid Sturgeon. This fish entered earth’s evolutionary record about 70 million years ago. “Pallid” means absence of color, and true enough, the pallid sturgeon is nearly white. It is one of the largest (up to 85 pounds), longest-lived (as long as 100 years) and ugliest (like a bizarre cross between a shark and an armadillo) fish species in North America. The fish is endangered because we wrecked the Missouri River.
