Secrets of hot compost in winter–I think. I hope.

How’d I get hot compost in winter? I’ll tell you: I cheated. I added lots of nitrogen-rich bloodmeal to replace the green stuff that provides nitrogen in summer. “Lots” here means a sprinkling over the whole pile—maybe a couple of tablespoons—after adding four inches or so of material. Cotton-meal should work just as well, but be sure it's organic: pesticides, which are used heavily on cotton, concentrate in the seeds, which are ground to make the meal.

Perhaps I should define "winter" here: for days last week highs were around freezing, but they've been warmer recently, with rain melting last week's snow. So it's cool rather than cold, but temperatures are predicted to drop again tomorrow.

The bin is of course central to successful composting, and I’m a little reluctant to reveal mine, since even a glimpse of it will probably reduce most of you to envious teeth-gnashing. However, if you promise to restrain your wails, I’ll bow to the inevitable. Here it is, a high-class affair cobbled together years ago from a few boards and some chicken wire, built near one of the West's loveliest fences:

Hot compost anyone? Read it and weep

Here’s a photograph, taken on Friday, Nov. 28:

Compost 123 degrees

That, folks, is a thermometer. It’s the thermometer in my compost. It reads (in case you can’t see it) a hundred and twenty-three degrees Fahrenheit. (123°F.)

Others may be grateful for family, friends, turkey, jobs, whatever; I’m grateful for  the compost heap (which I mis-typed as “heat,” a serendipitous error).

I built this heap on Tuesday the 18th, the day before surgery, and in the days just after, husband Steve brought me progress reports: 120° on Thursday, 140° on Friday. On Saturday I hobbled out to see for myself: 140°.

Compost to control plant diseases (revised)

So a day or two ago I was innocently researching away about compost and just for fun, hit the Google ‘scholar’ option to see what came up under the wide-open search term “compost.” (Toe surgery confines me for the moment to whatever I can find on the Internet; even the University library six blocks away is too far).

Lo and behold, I found myself looking at a number of articles dating back to the eighties and continuing right up to the present day about managing diseases with compost. Slap my ass and call me Judy, but I never heard of such a thing. Like a good metaphor, however, it makes sense as soon as I hear it: so many plant diseases are soil-borne that changing the soil balance would reasonably affect disease contraction, severity, and so on.

WHY Decomposition Uses Nitrogen (or, What I Learned Today #2)

A couple of weeks ago I wrote about what happens when sawdust decomposes. But the account was incomplete, and I am here today to rectify that error. Call me honest, call me obsessive; I’m going to set the record straight, sawdust-wise.

I wrote then that sawdust makes a lousy lawn fertilizer because it requires so much nitrogen to decompose, and it contains very little. So far, so good. But when I wrote that “it requires nitrogen to break down, and it’ll make use of whatever it can lay its sawdusty little paws on,” I misspoke.

I know what you’re thinking: sawdust does not have paws. But that’s not where I’m headed. No, what’s at stake here is not anatomy, but agency. It’s a mistake to refer to sawdust as making use of nitrogen or to suggest that sawdust “gets” nitrogen whether with paws, hands, or any other part of its being.

It’s a mistake, in a sense, even to refer to sawdust (or anything else) as decomposing, as if this were something that it did all by itself. In fact, of course, something decomposes it. And not just one something; lots of somethings. These somethings are called—brace yourself—decomposers.

And how did you spend YOUR morning? (A Nightmare, revised)

I had good intentions.

Yes, and now you’re halfway down the road to hell.

I just wanted to check one thing!

That’s how it starts. And what was so important it couldn’t wait till after you’d worked on your article?

I just wanted to figure out which zany blogger had said she wanted to “pull a Thomas Pynchon,” or was it “do a Thomas Pynchon”? Anyone who used a phrase like that, I wanted to know better.

So, you sacrificed your work to your social life, did you? In fact, to the possibility of an on-line, a virtual relationship—You read her blog, she reads your blog–or not. Touching. And what would it mean, anyway, to—how did you put it?—to“pull a Thomas Pynchon?” Who is he, anyway?

He’s a famous writer—

I never heard of him.

Yes, well. Anyway, he’s also famous for being invisible. He not only never holds an interview, but he actually disappeared years ago. No one knows where he lives. So to “pull a Thomas Pynchon—“

Yes, I understand.

So it took a while, but I found who said it; it’s Jane Perrone, who writes the Horticultural blog, amongst other gardening stuff.

Do go on.
