Our Compost Station

Nov 6, 2018

The stuff of dreams this is. We’ve been talking about it for quite some time and we finally finished it. Introducing our dream Compost Station.

FYI – that rogue chook shouldn’t be there

We’ve got humanure bays, a compost bin, worm farm, chickens and goat systems all clustered into one compact, pretty spot and it’s awesome. Why is it so awesome?

It’s wonderfully efficient having all these systems in one place. We can just go to one place to drop off food scraps, humanure and animal manures into various compost options. When I harvest chook or goat poo from the neighbouring yard, it’s dead easy as it’s all on the same contour and I only have to move it a leisurely 1m – 10m. So good.

The worm farm also functions as a seat so we can hang out and watch the goats in comfort (we like to do that a lot). Plus it’s rodent proof, being built from a enamel bath and hardwood frame. You can see a photo journey of it’s construction below.

Anton showing off the false floor needed for drainage, made from reo and shadecloth. 

Worm bedding is then placed directly on top. We’re using half composted straw, nice and moist for the worms.

You can then add chopped up food scraps straight top (and the compost worms)

A layer of damp cardboard (or a hessian sack or woollen blanket) keeps the flies away and moderates temperate and moisture. 

You can read more about building your own worm farm seat (or potting bench) here and what compost worms are here.

The humanure (from the compost toilets) system is ergonomic, tidy and safe with no lifting or handling of raw poo/wee. We’ve got a number of wheelie bins retrofitted to be the chamber for an inside compost toilet. There’s a tap on the bottom of each bin which directs all urine to underground infiltration system – very similar to what’s being done here. Once a bin’s full, it’s swapped for an empty one and the full bin sits in on of the bays until it’s composted for approximately 6 months (that’s what those two green bins are doing). Once ready, it’s then transferred into this new bay where it finishes the composting process with compost worms. At this point there’s no unpleasant smell at all, it’ll stay here for another 6 months or so at which point it’ll return to our orchards. Wheelie bin toilets are awesome – check out Natural Event and The Humanure Handbook for more inspiration.

Edit: You also need to know that we have a flush toilet and that this compost toilet is optional, not for public use and all inputs highly monitored :-). 

There’s not much in it at the moment, but it’ll build up over time. The front timber panels can be removed one by one for ergonomic access. 

Tree prunings we harvest for our goats can be stored easily while they wait to be chipped and put back onto the garden or into the goat/chook run. We harvest weedy Cotoneaster daily for them from our local forest and cycle the carbon back into our landscape once the goat’s have stripped all leaves off the branches. Until now, I’ve been make awkward piles of sticks and branches which get in the way of everyone and thing, not any more. That one cross piece you can see across the front is to help contain them.

The compost bin is rodent proof with a layer of vermin mesh added to its bottom to stop rodents creeping in. You can read and see how we did this here. 

The black bin to the right of the worm farm below is full of dry, brown carbon materials to add to the compost bin and occasionally into the worm farm if needed. Having a stash of ready-to-go carbon on hand helps your compost experience be a successful one as if you only put food scraps into a compost bin you’ll create an anaerobic disaster.

It’s beautiful. Built from salvaged corrugated iron from the local Tip Shop and hardwood timber from a local person’s bush block, it’s completely gorgeous. Why hide your compost bin/system behind the back shed where it’s cold and dark (and you never want to go) when you could integrate it into the hub of your garden?

One of the permaculture principles is “produce no waste”. While a lot of the success with this principle is wrapped up in reducing consumption, it also questions what we do with the waste we produce – this Compost Station is part of our answer for our property. Every morning I drink my morning cuppa staring out the window at this gorgeous creation of efficiency and nutrient cycling heaven.

Special thanks to Anton who built it for me – the ultimate expression of love.

Wondering what we do about large hot compost piles?

  • We like to make hot compost piles in different spots around the garden to benefit different patches of soil – once it’s mature we just spread the compost in place which is easier. So they’re a moving feast that we only make in Spring and Summer when we have bulk garden waste from crops we’re pulling out.

    Hi Guys
    A work of art.
    Make sure you do a test for lead leeching from the old bathtub…Bunnings sells the kit…I had to send two bathtubs off to the scrap metal merchant because of the issue…..can you please convince my partner Cath of the virtues of Humanure..in all other matters Permaculture she is perfect ( making rhubarb and beetroot chutney as I type)

    Loved reading about your system and thinking about how we can improve ours.

    I found the wire rodent mesh rusted out quickly, so I now use a double layer of square paving stones underneath my plastic compost bin. I also found a huge improvement in composting speed after I drilled about a hundred small air holes in to the bin. Only problem is the occasional cheeky tomato seedling making it’s way through the holes 😄

    Hey lovely, which bay do you put the chicken/host waste in?

    Hi, looks great and about to embark on similar. Question, do rodents and possums not find their way in given there’s no roof? Appreciate any advice. Ben

Mounding Potatoes – Or Not

Mounding Potatoes – Or Not

There are many varieties of potatoes (aka spuds) but only two key categories they all fall into. Determinate and indeterminate. Determinate potatoes don’t grow very tall and only produce spuds in one layer of soil so you don’t need to mound them. They also generally mature quicker than indeterminate types, a good thing to know […]
