The argument for encouraging biochar use as a ubiquitous household practice is compelling: Improved garden soil will increase food production where it has the most impact on energy demand. Implementing charcoal manufacture at a household level draws in a supply of yard prunings and workbench scraps that otherwise would be lost to non-charcoal alternatives. Unfortunately, finding even the most basic information on how to implement biochar use as a personal sustainability practice is discouragingly time consuming. In response I have started up a FAQ

Application of the charcoal to soils may be key to sustainability. Application of charcoal to soils is hypothesized to increase bioavailable water, build soil organic matter, enhance nutrient cycling, lower bulk density, act as a liming agent, and reduce leaching of pesticides and nutrients to surface and ground water. The half-life of C in soil charcoal is in excess of 1000 yr. Hence, soil-applied charcoal will make both a lasting contribution to soil quality and C in the charcoal will be removed from the atmosphere and sequestered for millennia.

Redox: soil pH's energetic dance partner. When pH changes, pE must also change in response. The reverse is true also. In soil, that response departs from simple mirroring. So much so that it can seem to be two separate dances. Soil pH and pE have different causes of change and different effective buffering agents. The term 'buffering' is replaced in a pE context - it is called poise. A stabilized soil pE system is referred to as a well poised system, differences in soil buffering versus soil poise account for the departure from 1:1 mirroring. Now for the exciting stuff. To many of us, what makes soil different than geologic material is that it is in an excited state, excited mostly by solar energy as facilitated by living processes. Unlike soil pH, soil pE is directly influenced by these energy fluxes.

Following the Kyoto protocol with respect to reducing emissions of greenhouse gases emissions, and EU energy policy and sustainability in waste management, there has been an increased interest in the reduction of emissions from waste disposal operations. From the point of view of nitrous oxide (N2O) emissions, waste incineration and waste co-combustion are very acceptable methods for waste disposal. In order to achieve very low N2O emissions from waste incineration, particularly for waste with higher nitrogen content (e.g. sewage sludge), two factors are important: temperature of incineration over 900°C and avoiding the selective non-catalytic reduction (SNCR) de-NOX method based on urea or ammonia treatments. The more modern selective catalytic reduction (SCR) systems for de-NOX give rise to negligible sources of N2O.

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.

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.

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.

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.

The North Dakota Farmers Union has successfully started a national Carbon Credit Program. It allows ag producers and landowners to earn income by storing carbon in their soil through no-till crop production and longterm grass seeding practices. There are also forestry (tree planting) and methane offset (manure digester) contracts. Forestry and methane contracts are available nationwide and have no enrollment date. Soil offset contracts are limited to established enrollment areas. (article includes map). Soil carbon characterization studies are needed to expand the enrollment areas.

The Godfather of Terra Preta, soil scientist Wim Sombroek (1934 - 2003) enjoyed a lifelong fascination with enhanced soil. The importance of plaggen soil in his native Netherlands impressed him at an early age, and early in the 1960's, he recognized in the Amazonian Dark Earths something familiar and precious. Before his passing, he assembled specific soil scientists challenged them to discover the process for making and sustaining a modern equivalent of the bio-char enhanced terra preta, what he termed terra preta nova. A great opportunity in answering Sombroek's challenge lies is surmounting the opacity of mutualistic rhizospheric species to traditional analytical approaches: only 1% of rhizospheric species are cultureable ala petri dish. We don't have a robust body of culture-independent studies against which to compare Terra Preta, so we are doubly challenged to reverse-engineer the phenomenon. Considering Wim Somboek's many noteworthy accomplishments, the perspective of his international leadership, and the late-in-life timing of his challenge, one senses he is pointing us to a mystery fundamental to understanding soil in new and exciting ways. This happens at a time when the soil science profession is in dynamic transition and sorely in need of a unifying vision. Wim Sombroek has given soil scientists a most welcome and worthy quest.

Peak Energy has a long post on Terra Preta that brings together what has been established on the subject. As of yet, there is no direct mention of the role of glomalin , just a minor mention of the mutualistic fungi that produce it. Glomalin is an unvalidated factor in Terra Preta formation that several of us sense will be demonstrated by soil research as fundamentally important. Spurred on by back40, I am fascinated with bio-char, Terra Preta's key soil amendment. Last summer I constructed a small charcoal retort out of a cracker tin. I used it to produce small pilot batches of low temperature charcoal. Hoping to transform my simple charcoal into a reasonably bio-char-like material, I am currently composting my bits.

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.

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.

Around the world, soil is being swept and washed away 10 to 40 times faster than it is being replenished, destroying cropland the size of Indiana every year, reports a new Cornell University study."Soil erosion is second only to population growth as the biggest environmental problem the world faces," said David Pimentel, professor of ecology at Cornell. "Yet, the problem, which is growing ever more critical, is being ignored because who gets excited about dirt?"

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.

Despite a lack of evidence that peer review works, most scientists (by nature a skeptical lot) appear to believe in peer review. It's something that's held "absolutely sacred" in a field where people rarely accept anything with "blind faith," says Richard Smith, former editor of the BMJ and now CEO of UnitedHealth Europe and board member of PLoS. "It's very unscientific, really." What's wrong with the current system? What could make it better? Does it even work at all? Indeed, an abundance of data from a range of journals suggests peer review does little to improve papers. In one 1998 experiment designed to test what peer review uncovers, researchers intentionally introduced eight errors into a research paper. More than 200 reviewers identified an average of only two errors.

A hardy new grass called "HiMag" may help protect cattle, sheep, and goats from an affliction known as grass tetany. When ruminants�animals with four stomachs�have too little magnesium in their blood, grass tetany can result. Also known as hypomagnesemia, grass tetany causes an estimated $50 to $150 million in livestock production losses each year in the United States.

Conner's A People's History of Science: Miners, Midwives and 'Low Mechanicks' does for science what Howard Zinn did for American history. It is an altogether winning attempt to tell the story of the ordinary working person or peasant's contribution to our knowledge of the natural world. Just as scholars like Zinn remind us that a slave, Crispus Attucks, was the first casualty of the American Revolution, so does Conner show that humble people were on the front lines of the scientific revolution.

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.

Abstract: While the eighties of the last century were a time of local automation for libraries and the nineties the decade in which libraries embraced the Internet and the Web, now is the age in which the big search engines and institutional repositories are gaining a firm footing. This heralds a new era in both the evolution of scholarly communication and its agencies themselves, i.e. the libraries. Until now libraries and publishers have developed a digital variant of existing processes and products, i.e. catalogues posted on the Web, scanned copies of articles, e�mail notification about acquisitions or expired lending periods, or traditional journals in a digital jacket. However, the new OAI repositories and services based upon them have given rise to entirely new processes and products, libraries transforming themselves into partners in setting up virtual learning environments, building an institution�s digital showcase, maintaining academics� personal Web sites, designing refereed portals and � further into the future � taking part in organising virtual research environments or collaboratories. Libraries are set to metamorphose into �libratories�, an imaginary word to express their combined functions of library, repository and collaboratory. In such environments scholarly communication will be liberated from its current copyright bridle while its coverage will be both broader � including primary data, audiovisuals and dynamic models � and deeper, with cross�disciplinary analyses of methodologies and applications of instruments. Universities will make it compulsory to store in their institutional repositories the results of research conducted within their walls for purposes of academic reporting, review committees, and other modes of clarification and explanation. Big search engines will provide access to this profusion of information and organise its mass customization.

While the science owes a tremendous debt to agriculturists, engineers and geologists, soil science is not subordinate to any other discipline. Any real disagreement about standing were eliminated in 1924 when the International Council for Science accepted the International Union of Soil Sciences (IUSS), as a full member , rather than placing soil science within either the IUGS or IUBS.

This article presents results of a survey undertaken as part of a series of work packages under a joint initiative by JISC and SURF to explore the attitudes of authors in the UK and the Netherlands towards Open Access. These and other results seem to reflect a desire on the part of academics to change the balance of rights within copyright between authors and publishers in scholarly communication journals. Libraries and academic institutes are already taking part in the scholarly communication copyright debate and could use these results to align their positions with the academics' views.

As water is so common-place, it is often regarded as a �typical� liquid. In reality water is most atypical as a liquid, with its properties at low temperatures quite different from its properties when hot. It has often been stated (e.g. [127]) that life depends on these anomalous properties of water. In particular, the large heat capacity, high thermal conductivity and high water content in organisms contribute to thermal regulation and prevent local temperature fluctuations, thus allowing us to more easily control our body temperature. The high latent heat of evaporation gives resistance to dehydration and considerable evaporative cooling. Water is an excellent solvent due to its polarity, high dielectric constant and small size, particularly for polar and ionic compounds and salts

Rapid turnover of organic matter leads to a low efficiency of organic fertilizers applied to increase and sequester C in soils of the humid tropics. Charcoal was reported to be responsible for high soil organic matter contents and soil fertility of anthropogenic soils (Terra Preta) found in central Amazonia. Therefore, we reviewed the available information about the physical and chemical properties of charcoal as affected by different combustion procedures, and the effects of its application in agricultural fields on nutrient retention and crop production. Higher nutrient retention and nutrient availability were found after charcoal additions to soil, related to higher exchange capacity, surface area and direct nutrient additions. Higher charring temperatures generally improved exchange properties and surface area of the charcoal. Additionally, charcoal is relatively recalcitrant and can therefore be used as a long-term sink for atmospheric CO2. Several aspects of a charcoal management system remain unclear, such as the role of microorganisms in oxidizing charcoal surfaces and releasing nutrients and the possibilities to improve charcoal properties during production under field conditions. Several research needs were identified, such as field testing of charcoal production in tropical agroecosystems, the investigation of surface properties of the carbonized materials in the soil environment, and the evaluation of the agronomic and economic effectiveness of soil management with charcoal.

Why people living on hills overlooking many rivers in Brazil two millennia ago devised this approach is still a subject of debate, as is how they added all the extra organic content and ensured the soil was teeming with beneficial bugs and other micro-organisms. A modern technology called low-temperature pyrolysis can produce bio-char on an industrial scale. Using wood or agricultural wastes for fuel, pyrolysis would generate heat for electricity while also actually reducing net emissions of carbon dioxide since the organic matter would otherwise decompose. "This might be the beginning of a bio-char revolution," Lehmann says.

Applying the knowledge of terra preta to contemporary soil management can decrease the amount of fertilizer needed, because bio-char helps retain nitrogen in the soil as well as higher levels of plant-available phosphorus, calcium, sulfur and organic matter. The black soil also does not get depleted, as do other soils, after repeated use. Producing and applying bio-char to soil would not only dramatically improve soil and increase crop production, but also could provide a novel approach to establishing a significant, long-term sink for atmospheric carbon dioxide.
