Growing a Revolution: Bringing Our Soil Back to Life

In Growing a Revolution David R. Montgomery advocates farming practices that center upon building healthy soil. Conventional agriculture depletes soil of nutrients and gradually leads to an erosion of topsoil. Fertilizer attempts to restore some of the critical nutrients. However, it does not restore the important micro organisms that help make healthy soil. Also, a good portion of the fertilizer runs off, contaminating water supplies. In addition, the tendency to plant the same crops over and over makes them more subject to pests, requiring more pesticides, leading to resistant pests and more pesticide use.
He advocates for "no till farming" with crop rotations. Rather than plow the ground, the previous crops are used for mulch. New crops (of a different variety) are planted in the ground. The organic matter decays and improves the health of the soil. The rotation and planting of cover crops helps improve the health of the soil and make it more resistant to pests. This healthier soil is also much better at holding water than plowed soil. No till farming can be either organic or conventional. In general, it may more closely resemble organic farming because of less dependence on pesticides and fertilizer. However, the practice can be done with either conventional or organic approaches. (Pest control with conventional would still be an acceptable if needed.) An initial shift to no-till farming may see a drop in productivity. However, as the soil health builds up, productivity tends to be similar to conventional farming. However, the input costs of no-till farming practices are much less. Thus, even when productivity is lower, the no-till farms are still much more profitable.
The main problem with no-till farming is that there is not a business interest behind it. It results in lower demand for big agrichemicals. Perhaps what they need to do is get big farm implement companies behind it. There has to be a good deal of money behind "no-till" tractor equipment. Perhaps seed companies could also get behind selling more seeds. (Though the author does discuss a breeder who is working on perennial grains.)
The author also takes the discussion across the world. In Africa, he meets with a no-till advocate. In Asia, society has been returning human waste to the ground as fertilizer for many years. (Cities even sell their waste to farmers.) Even Tacoma sells processed sewage as fertilizer. Farmers in North Dakota have adopted no-till to significant success.

And some more books (Nickel and Dimed, The Great Bridge, Lord of the Flies, Crucial Conversations)

Barbara Ehrenreich - Nickel and Dimed: (2001) A well-off, highly educated writer attempts to 'live with the lower classes' to see how things really are. However, her effort comes across as somewhat half-hearted. Her insights seem to show more of the middle-class snobbery than anything else. While attempting to live the life of a lower-class service worker she looks down at the "wealthy" people she is working for, while also looking down at the "poor" people she is working with. One interesting is the disparity in drug policy. In her 'upper middle class' life, her Marijuana usage is no big deal, and doesn't impact her ability to work. However, in her 'lower class' life, the fear of marijuana detection cause her to turn down 'good' jobs.

David McCullough - The Great Bridge: The Epic Story of the Building of the Brooklyn Bridge (1972) : I listened to an abridged audiobook that, rather unfortunately, turned this book in to a biography of the Roeblings. The audiobook was 'nice enough' to provide brief summaries of the missing chapters, so I knew I was missing what sounded like good discussion of the actual building of the bridge.

Golding - Lord of the Flies (1954): When boys are alone, things start out alright, but then gradually drift in to savagery. Would somebody be tried for murder when they returned to civilization? Or would there be a big civil law suit? There would probably be plenty of rationale for just acting out in the harsh conditions. However, how would you rationalize other people not being "as bad"? What would have happened if they were not "rescued" at just the right time?

Patterson, et. al. - Crucial Conversations (2001): Turn brain on at the precise moments when brain wants to go off to "fight". Remember the big goals, not short term "win" in a conversation.

(More details of these below at updated post due to tag limit)

Russell Shorto - Descartes' Bones: The odd history of Descartes' bones show some of the prejudices of the "religion" of rational thought. This is filled with irony. Descartes was religious, yet is treated as the father of a (primarily atheist) rationalism. His bones become a "relic" for those against the church. He sought to find the means to overcome death, yet died in middle age. This book contains plenty of interesting tidbits on the philosopher and his followers and philosophy. However, the main point is the trail of his bones and how they relate to societal sentiments.

Stephen Mitchell - Gilgamesh, a new English version: This is really graphic. It does have similarities to the "Joseph" and "Noah" stories from the Bible. Are they both referring to the same previous event?

Barbara Kingsolver - Animal, Vegetable, Miracle: local eating. Properly raised domestic animals do have a place in the food chain. (They can convert non-human-edible plants in to human food. They have also been adapted to live with humans, and wouldn't do very well in the wild.) This provides a very balanced approach to environmentally sustainable food habits, with an emphasis on local and organic to decrease energy consumption, and even eat with a lower cost. The narrative provides an example of "mostly" local eating for a year. It does require hard work in the yard. However, good food plus hard work is exactly what the doctor ordered...

Thomas Aquinas: Interesting rational religious philosophy
