John Todd on soil and the carbon cycle

John Todd, of Living Machines fame and the New Alchemy Institute, has an interesting essay on http://www.thesolutionsjournal.com/node/634 about the need for our urban and industrial society to understand the foundational role of soil, and the carbon cycle.

Living from livestock: Sam Bingham's 1984 classic available for download

In 1984 Sam Bingham wrote a short book for Navajo country called Living from Livestock. Though one or two items are outdated (such as the recommendation to build radial grazing cells) it is a wonderfully illustrated and trenchant introduction to the relationship of grazing to ecosystem function in an arid environment. Thanks to Sam we are able to offer it as downloadable pdfs. (Right click, Save As, to download.)

From Wagga Wagga, a farmer's guide to increasing soil organic matter under pastures

The New South Wales Department of Primary Industries has an interesting 60-page guide to growing soil organic matter in pastures.

"This book is based on findings from a three year project investigating soil carbon levels in pastures under different management practices in south east NSW. It is designed to be of practical use to farmers who want to increase their soil carbon levels. It includes basic information on soil carbon and reports the project's findings regarding the impact of pasture management on soil carbon."

Christine Jones: new paper on soil carbon in Australia

Australian soil scientist Christine Jones has a new paper out that summarizes much of her conclusions about the soil carbon opportunity. "For some time, analysts have tipped carbon to become the world’s most traded commodity.

Allan Yeomans on climate change and soil

Allan Yeomans, author of Priority One: Together We Can Beat Global Warming has a series of videos on climate change and soil. Here are Parts 1 and 2.

Outliers

In general, statistical accuracy increases with the square root of sample size. Doubling your sensitivity and accuracy quadruples your cost. It's a power law, not a normal distribution, and it pushes us toward extremes.

In measuring soil carbon using traditional sampling, what this means is that the high achievers are easiest and cheapest to measure (circled red in the diagram below). A sampling scheme that is adequate for measuring a large change in soil carbon between an initial baseline and resampling, may not yield a significant result if the change turns out to be small.

Allan Savory interview

An excellent interview of Allan Savory by Jonathan Teller-Elsberg deals with the difference between reductionist research and process-oriented management, and brittle and nonbrittle environments. Savory discusses why reductionist research and conventional paradigms limit innovation.
