Agricultural Runoff and Ohio’s Senate Bill 1

Agricultural Runoff and Ohio's Senate Bill 1

In response to the August 2014 shutdown of Toledo’s water supply due to microcystin contamination, the Ohio legislature passed Senate Bill 1, which regulates fertilizer and manure application to farm fields. Essentially, the new regulations prohibit spreading manure or fertilizer in the Lake Erie Watershed when soils are frozen, snow-covered or saturated, or if there is a more than 50% chance of at least one-half inch of rain in the …

Field Drain Tile and the “Re-Eutrophication” of Lake Erie

Field Drain Tile and the "Re-Eutrophication" of Lake Erie

Algae Blooms, Microcystin and Phosphorus It’s been over a year since Toledo, Ohio and surrounding communities shut down public water supplies due to an algae bloom and microcystin contamination in western Lake Erie. Was the trouble a “one-off” or can we expect more of these events in the future? While attending a seminar this year hosted by the Michigan Chapter of the Soil and Water Conservation Society, my interest was …

North is Not Up, Nor is South Down

North is Not Up, Nor is South Down

I can’t count the number times I’ve heard a TV weather person make a statement akin to “this line of thunderstorms will pass below New York by Thursday afternoon.” Yes, and while it’ll be sunny up top on the street, if you’re working all day in the subway, or on underground utilities, you’ll need an umbrella. Be prepared to seek safety in daylight as those storms may produce lightning and …

Art in Science: Kubiena’s Soil Profiles in Watercolors

Art in Science: Kubiena's Soil Profiles in Watercolors

Photographs of soil profiles are often disappointing. Usually the subject is a hole in the ground where light is dim and the surrounding ground surface is light. Getting a good, representative photo of a soil profile can lead to acres of frustration. W.L. Kubiena worked as a soil morphologist in the last century and from a practical standpoint, probably only had access to black and white photography. He opted for …

Uncovering a Soil Mystery Using Micromorphology and Petrography

Uncovering a Soil Mystery Using Micromorphology and Petrography

This is the second in a series (link to 1st) about the genesis of the Success soil, which was the topic of my master’s research. This part has to do with using petrography to identify soil constituents and examine soil fabric to help understand soil forming processes in a particular case. Soil fabric consists of soil plasma and skeletal grains, which can be distinguished under magnification. W.L. Kubiena was an …

Unearthing a Soil Mystery Using Differential Solution Analysis

Unearthing a Soil Mystery Using Differential Solution Analysis

Some years ago while in graduate school at the University of New Hampshire, I was presented the opportunity by my advisor, Dr. Chris Evans, to solve a hard soil mystery resting mostly unnoticed except to those who had to work in it. Found on steeper slopes under coniferous forest, for builders, the Success series can be troublesome. It’s effort enough to dig any soil, but the Success soil is especially …

Update: American Farm Bureau Federation et al. v. EPA Oral Arguments

American Farm Bureau Federation, et al. v.

The program calls for a 25% percent cut in nitrogen, 24% cut in phosphorus, and 20% reduction in sediment loads by …

Symphony of the Soil is a Beautiful Film Documentary

I can’t say enough about this film made by Deborah Garcia. Symphony of the Soil is available here through October 10 for free viewing. The film has wonderful macro and micro videography and a tremendous sound track. The passion these scientists providing narrative have for their subject comes through loud and clear. I try to stay away from superlatives, but can’t help it with this documentary. Watch the film. If …
