Charcoal cannot replace the need for adding mineral nutrients.

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.

Data indicates microbes have more difficulty adapting than previously thought.

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.

"Teaming with Microbes", by Jeff Lowenfels and Wayne Lewis. Foreword by Elaine Ingham. Strong soil science orientation. Well organized. Extensive index. Valuable guide to labs and suppliers. Looking forward to actually reading it.

The National Society of Consulting Soil Scientists supports S. 2695, the Federal Research Public Access Act of 2006, as introduced, in that it reflects NSCSS goals regarding the free exchange of information, promoting soil science technology, and eliminating unfair competition from taxpayer supported entities.

A discussion of NSCSS' role as a client of soil science education comparing SSSA's recent message "Making Soil Science Education Relevant to Societal Needs" to NSCSS' Education Project page.

...engaging with the organic myths of pseudo-environmentalists and their historically impoverished views of agriculture.

Soil scientist takes issue with a beautifully written journalistic essay on soil and soil erosion. He points to two scientific discoveries, terra preta and glomalin, relevant to regenerating damaged soils in the Third World.
