Of doo-doo and Doo-Dah

I hope to be back in blogging shape again soon, but a family emergency has occupied most of my energy and time of late. Even so, I can't resist calling your attention to this wonderful reprint (repost?) of Daniel Chamberlin's profile from a 2007 Arthur of "Sodfather"/"California compost wizard" Tim Dundon. The main focus of the piece is a wild tale that, "like any good gardening story, encompasses Hollywood producers, fires, suicide, PCP injection, a nude Quaker iconoclast, standoffs with city officials and a violent pet coyote." But just as fascinating--to me, at least--is the way Chamberlin interweaves an entire scientific/socio-political history of organic farming/gardening dating back more to approximately 2400 BC. The prose is both witty and informative, as we see in this passage that explains what all those creepy crawling things are up in my compost pile:

The first stage of decomposition in composting is chemical: microscopic organisms flock to the dead thing and start to secrete enzymes that break it down on a cellular level. As bacteria, saprophytic mushrooms and other fungi eat and digest, they give off considerable heat, causing compost piles to steam and occasionally even catch fire from the trillions of tiny post-dinner bacterial farts. ...

... As the chemical decomposers make the dead organic matter a bit more malleable, the physical decomposers start to show up. Millipedes, sow bugs, springtails and snails are happy to chomp up the plants. Flies arrive bringing more bacteria to the buffet, leaving behind eggs and maggots for spiders, centipedes, mites and beetles to eat. Ants replenish the fungi, transport minerals from within and without of the pile and eat plants and insects. But the most accomplished of all the decomposers is without question the earthworm. ... These original slimy alchemists eat dirt and shit out the organic equivalent of gold: castings, also known as vermicompost. Castings enrich the soil with nitrogen, calcium, magnesium and other minerals, in addition to increasing its ability to retain water. And they attract more earthworms, too.


Speaking of alchemy, Chamberlin begins his piece elaborating a connection that has long been implicit and intuitive to me:

Alchemists were up to plenty of things, many of them having to do with relating to the natural world—and understanding its processes of transformation and transmutation—in philosophical and spiritual dimensions that transcended traditional religious thinking, both Christian and pagan, and preceded modern scientific thought. The whole “lead into gold” thing was but the most lucrative of the alchemical —or hermetic—practices in the eyes of the monarchs and rulers. Alchemy’s material prima as Peter Lamborn Wilson writes in the recent collection Green Hermeticism: Alchemy and Ecology, “can be found ‘on any dung hill.’ Hermeticism changes shit into gold.”


In short, the article suggests bridges between all kinds of things I'm interested in (see the tags/labels below), and makes a perfect capper to my reading of Amy Stewart's earthworm book, which I've been intending to write more about--and which I surely will write more about when the time is right.

Soil-ent green

Uh oh--as long as I'm enjoying my brief residence on Blotanical's list of the 100 Newest Garden Blogs, I should probably not leave a delightfully eccentric pop song/music video as the first entry newcomers see, even if it does revolve around the garden. Wouldn't want anyone to get the wrong idea. (For the wrong idea, feel free to visit my other, longer-established blog, which generally has very little to do with plants at all.)

In a hasty attempt to appear more conventionally garden-focussed, allow me to call your attention to this eye-opening post at Gardening Gone Wild about plant nomenclature. Actually, the plant part was fascinating enough (and made me totally want to shell out $3 US for the Chiltern Seeds catalogue for what sounds like some terrifically entertaining prose), but what really caught my eye was the revelation that

Soils have names too, but the current system of soil taxonomy is a whole lot more straightforward than plant taxonomy. There are six levels: order, suborder, great group, subgroup, family, and series. Each one of these represents quite a lot of information, and a bit of each level goes into making up the name of any soil.


I did not know that! Handy timing, too, as I've just started reading Amy Stewart's book The Earth Moved, which has me thinking about the contents of the dirt below my feet. I've been looking forward to reading the book since I first learned about it, and I'm only on chapter one so I don't have much to report yet, but I certainly share Amy's provocative observations in the "prologue" :

... I realized that I understood very little about the plot of land under my own house. Do I even hold title to this ground twelve feet down? What about twenty, fifty, a hundred feet? .... Is this little piece of earth mine, all the way down to its red hot center? ... And who lives down there, under my house? ... Millions--no, billions--of organisms inhabit my little piece of land, and it shocks me to realize how little I know of them.


I've been thinking mainly about those unseen inhabitants, but I now realize that even the soil itself has a complex identity, one that reaches far beyond such categories as clay (that's me), sandy, and loam.
