Turning a compost pile
Written by Kirsten   
Wednesday, 21 November 2007

It's been two weeks now and I've been a-turnin' my compost... and it's working! Sortof. I think I should have ripped up all that newsprint - it's proving a right pesk to turn with my pitchfork - it just becomes great gloopy clumps of glossy advertisements and happy-families pamphlets from the bank, all bonded together as if by magic to thwart my composting progress. But I am undaunted... I just mutter darkly at them and enjoy poking various political leaders through the eye with my pitchfork as I turn my pile...

So the compost is heating and life is fermenting (literally) in there... Nick and I are having fascinating anthropological discussions about its components. About why the corn flakes packet seems to take the longest to break down (we rekon it's coated in arsenic to repel rodents or similar - yech), followed closely by any and all full-page car ads... there might be a thesis in this, actually... anyone?

I'm planning to harangue my scientist sister into figuring out a wicked compost recipe which uses lots of the glossy newsprint, but still ends up not-too-toxic at the end of the composting process. I now see all magazines as simply inert carboniferous material, just waiting to be turned into rich soil humus... the trouble is, I don't really know how best to deal with the suspended animation caused by all their glossy coatings and such, and how to negate those chemicals within the composting process... there might be another thesis in this, actually... anyone?

Anyway. I wrote down the full process of turning compost over in resources under How to make compost: Pt2 - have a look. Slowly but surely, I will become a composting machine...

Woohoo, yay for dirt! Some day when I have a yard I'll have to try this.

I'm trying out a jar of olives from your previous clip. Keep up the good work!

When you said you had anaerobic bacteria in your compost, are you sure? was it smelling bad? anaerobic bacteria only grow when there's not enough oxygen and if you're turning the pile every 2 days there should be lots of oxygen. if its white powder might it be mould/fungi?

I wrote about the bacteria in compost on my blog here. this post was a correction of a previous post which I got wrong. i'm always adding to my compost knowledge.

My compost is very slow because i'm too lazy to turn it as much as you do, altho i aerate it once a week. Mine never gets hot enough for thermophilic bacteria, but it breaks down eventually.

And when you wrote that you put glossy magazine paper in your compost, I thought that was a no-no because of the ink used. I put torn up cardboard in mine sometimes, but if its glossy I don't. I've heard that even coloured news print it not so good, although I put any newspaper in my worm farm (every now and then it has coloured pages) and the worms quite happily eat it.

I hope your earthworks this week are going well.

hi clare -

yeah pretty sure the white stuff was anaerobic bacteria - the compost got a bit hot at one point, even tho we were turning it - we stuck a bunch of fresh urine on it a couple of times, and i think that was a bit too much nitrogen action for it... it was as i've seen anaerobic bacteria described within soilfoodweb literature...

re the glossy newsprint, yes i have heard the same thing regarding heavy metals and inks etc. However, we really wanted to work with what we had, and figure out how to use what we had (ie glossy newsprint) - ultimately I'd prefer not to use it, but until we have other resources, I'd prefer to use what we have on-site...

all the best, k
