transect points: The Smell of Healthy Soil

Actinobacteria are a hyphae-producing soil bacteria that, in appearance and behavior, have more in common with soil fungi. The spores of Actinobacteria have a distinctive, earthy smell we often associate with rainfall. The smell comes from a compound, geosmin, which translates to "earth smell". The human nose is exquisitely sensitive to geosmin, able to detect it at concentrations down to 10 parts per trillion.

transect points: Triclosan, Triclocarban Concern

The environmental persistence of these compounds, used as an antimicrobial agent in hand soap, is remarkable. More than a million pounds of these chemicals flow into the nation's sewers every year. Between 50 and 75% of this ends up land applied as sludge. Triclocarban has been determined by the FDA as having no verifiable benefit. Despite a lack of evidence that these compounds accomplish anything beneficial, usage rate is very high among consumers. Among the households I have surveyed, it approaches saturation. It makes little sense to land apply recalcitrant compounds that needlessly get rid of soil microbes. Fomenting the growth of resistant strains of disease organisms is only one concern. Soil functional capacity is largely mediated by living processes. It is the height of folly to jeopardize those functions for a useless consumer item.

transect points: Soil Science has Changed

Edaphology is the study of soil (edaphic) effects. Until about 25 years ago, it was mostly synonymous with agricultural soil science as distinguished from pedology, the study of soil in its natural setting. Edaphology now encompasses the new field of environmental soil science, with its more formal emphasis on interdependent living processes in soil.

transect points: My 2007 Field Season Begins

In the Yakima Valley, with its 500,000 irrigated acres and its network of leaking canals, irrigation induced seasonal wetlands are common. In the floodplain, upwelling hyporheic / phreatic river water can be masked by irrigation induced hydrology, but only while the canals are full, or recently so. During this January visit, long after irrigation diversions have ceased, there was no mistaking the dominant river-induced groundwater hydrology at the site.

http://transectpoints.blogspot.com/2006/12/invasive-earthworms.html

Research shows that invasive earthworms are damaging forest soils and are a menace to species diversity. The problem is most often associated with formerly glaciated regions, where native populations of earthworms are not present. Comparing soil in front of the invaders to post invasion conditions demonstrates that these worms cause soil compaction, reduced soil fertility, and increased erosion. It appears that these invaders are capable of alterations deep enough into the soil profile to result in a change in soil taxonomic classification at the order level. Other concerns are damage to rhizosphere functions, impairing soil carbon sequestration capacity.

Mechanisms of terroir: how soils affect the taste of wine

The most convincing indications in the scientific literature are that the effect of soil type is through its physical properties, and more specifically, through the water supply to the grapevine. Nevertheless, it’s worth taking a look at recent research on the indirect effects of mineral nutrition on plant physiology. Although it seems clear that there is no direct link between soils and wine flavour, by framing their activities within the context of a soil-focused worldview and trying to get a bit of somewhereness and minerality into their wines, winegrowers might be vastly increasing their chances of making interesting wine. And that’s something the world needs more of.

Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and other aquatic ecosystems. Each year about 10 million ha of cropland are lost due to soil erosion, thus reducing the cropland available for food production. The loss of cropland is a serious problem because the World Health Organization reports that more than 3.7 billion people are malnourished in the world. Overall soil is being lost from land areas 10 to 40 times faster than the rate of soil renewal imperiling future human food security and environmental quality.

"Yet, the problem, which is growing ever more critical, is being ignored because who gets excited about dirt?"

transect points: Missoula Soil Science Consultant Speaks

Tell someone you are a soil scientist and it invariably requires an explanation of what you do. It's interesting that few of us do the same things and the telling of it reveals much about the person as well as the community they serve. For that reason I like to collect other folks' descriptions of their work. Certainly the telling of Barry Dutton's life work stands among my favorites because he built his business from scratch in a particularly cost-conscious region. He did it largely without the benefit of the 2 main drivers of regional soil consulting booms: booming suburban sprawl and booming energy prices driving increased well drilling and surface mining for coal and oil shale. I've heard several iterations of Barry's telling over the years and look forward to future installments.

Carbon sequestration in tallgrass prairie soil

Over the course of an eight-year open-top-chamber CO2-enrichment (to twice ambient concentrations) study of a pristine (annually burned) tallgrass prairie north of Manhattan, Kansas, USA, which was composed of a mixture of C3 and C4 species, Williams et al. measured changes in the active, slow and passive pools of carbon (C) and nitrogen (N), with the goal of determining how they were impacted by the doubled atmospheric CO2 concentration of their reasonably long-term experiment.
