Compost bins work

Our compost bin has been full for months now and we have just been adding food scraps to it regardless. The time has come to empty it, do something with its content, and start afresh. My husband proceeds to dig it out. The first wheelbarrow is ready to go. "You better test it", he calls out. I grab a sample and run over to the microscope.

It's beautiful. It is rich in bacteria, and it has a good number of ameaba in it. Not too many hyphal fungi in there, but a few potential hyphal fungi spores. It looks and feels great. I run out of the house with thumbs up. The wheelbarrow departs towards our other compost heaps. (Had the thumbs been down, the wheelbarrow may well have departed in the direction of Bob's valley. I guess we will never know.)

So what did it look and feel like?
Soil. Absolutely crawling with worms soil. Really nice, little bit sticky, not too wet, but definitely moist, soil. Crawling with worms. Dark dark brown, almost black in colour. And did I mention the worms?

What can it be used for?
Growing most garden plants - veggies, flowers, herbs. Not trees though. It needs more hyphal fungi to grow trees. And it's probably too rich for some veggies. I am not an expert in this yet. Watch this space.

What did we make it in?
In normal compost bin. One of those that just stands on the ground, and worms from the ground can get into it. (And they did get into it.) It has a lid on top. It's round, and about 50cm in diameter at the top. Bit wider down the bottom.

How did we make it?
We put all our food scraps, except for meat and bones, into it. So this included all vegetable, fruit and fish matter. (Yes, fish too! Including fish bones.) Tissues. Tea bags. Egg shells. Bread, rice, pasta. Onion and garlic peel. Orange and lemon peels. Avocado seeds. And when my daughter had not finished her dinner, it went into the compost too. Meat and all. (Please do note that these were usually very small amounts, like about two to four teaspoons, and it happens very infrequently. Perhaps once per three months.)

By the time we were digging it all out again, everything (except the fresh stuff on top) had been decomposed. The only thing we could recognise was the egg shells. And let them sit there I say. They provide great air pockets!

How long did it take?
We started the compost bin either in late 2006 or early 2007. After the first six months it was moved, together with all contents. About 18 months ago it was full, but then during a hot spell it sank down by 1/3rd. So we kept filling it up. We only filled it up on weekends, which is why it took so long to fill.

Mothers' Day

Mothers' Day was few months ago. I know. In our family, we have a particularly poor photo download and publish process. So I only found these snapshots recently, and thought they were worth sharing.

This year, for Mothers' Day, Sabina took me out horse riding in the state forest. As it was a bit of an "occasion", Crownie had to be plaited up.

We got to Dead Cow, and Sabina was so exhausted, that she needed to stop for a picnic.

This left me holding onto the horses.

Then we rode back home.

And here's a tip from Sabina. "This is a great way to celebrate Mothers' Day."

Credit Kid

"Mama, what do you need?", Sabina jumps onto the bar stool at the kitchen bench, bear in one hand, bag in the other. I gaze carefully, wondering what sort of game we're playing now. "Can you get me some milk, ham and cheese?", I ask. "No", she responds. "I don't have those, but I can sell you this purple ball for a dollar." She produces a purple ball from the bag.

"A dollar you say?", I quizz, "ok. Looks like an alright deal. But listen, can I put that on credit?" "Yes you can," she responds. I commence writing out an old fashioned, "IOU" credit note. "Mama, give me your card," says Sabina. I stare. "Mama, you need to give me your card," insists the little girl. I pick up the closest business card lying around and hand it to her. "I need to snap it", she says impatiently. "Mama, give me that box so I can snap it." Bewildered, I pass the said ice cream box, which has a little groove at the edges.

Sabina grabs the box, swipes the card through the little groove, punches something into the box, then looks at me. "Mama, but where's the little piece of paper that comes out the top?" I hand her the IOU note. She pretends that it comes out of the box, and the transaction is complete. "Here Mama, here is your card back, here is your ball", she leaves the items on the kitchen bench and packs up ready to depart.

"Sabina", I say, "you 'swipe' the card. Not 'snap'. Swipe."

Afternoon tea

We're working outside, in the garden. Icy wind blows through the rocks we're trying to move with the tractor.

Three muffins.
Three minutes.
Gone.
Three smiles.
A chocolate crumb left in the corner.

Work resumes.

Garden path

We are trying to build a path in the garden, that will go all the way around the house. It will allow Sabina to do laps around the house on the bike, it will mean that visitors don't need to tramp across bunches of wet capeweed from their car to the house. It's a great idea.

In order to build the path, we need to move a few rocks. Well ... when does a rock stop being a rock and become a boulder? I think we need to move a few boulders. Pete brings in the tractor to help. Without it, we would still be standing over the rocks with a cup of tea. But even with it, the work is a feat of horse power and simple engineering. Wooden planks protrude at all angles as a rock is levered out of it's bed. Some of these rocks are like ice bergs - you only see 10% above ground.

Once the rock is "loosened up", the tractor pulls them out. We use the scoop for this, and it's a game of hit and miss. Sometimes, the rock is 3/4 out, then the scoop looses grip, and it rolls back in. Other times, the tractor tyres start spinning slowly, as it tries to win a tug of war with a stubborn rock. Pete estimates that some of the rocks weigh as much as the tractor.

Most of the rocks just need to come out. But one particular rock needs to be moved, and positioned carefully to fit in as the end piece of a rock wall. We roll it out, we roll it in, we jiggle with the wooden planks and the crow bar. We just need it another inch closer to the other rock. We roll it out again. The tractor holds it in a precarious position, while we dig away more soil behind it. What a shame we don't take a photo. We roll it back in. More jiggling - I suspend my weight on the crow bar in the process. More planks. Finally, it's done. It looks sensational. Like it belongs there.

Compost Analysis

I set the microscope up on the kitchen table. Sabina dances around it impatiently.

I open the little jar with a compost sample and put it under the tap. "You're supposed to use distilled water, otherwise you might be introducing organisms", I muse. I look around. We don't have any distilled water. I turn the tap on, and start agitating the little jar.

Five minutes later, I pippette the murky solution onto the slide, Sabina breathing heavily over my shoulder. I slip the slide under the lense. "Mama can I have a look?" "No, not yet."

I turn the microscope on, and focus the lense. Even before I flick to maximum magnification, I see a nematode. A tiny little worm, moving left and right across the slide. I stand aside, and Sabina pokes her head over the lenses. She sees the nematode. Silence. Then she's off to play.

I observe the nematode for a while, trying to judge whether he is a good guy nematode. Then I go on with my analysis, or assay.

There is a fair bit of bacteria there, and a lot of amebea. But the amebea seem to be quite inactive. Very little fungi. But the fungi that I do find is amazing. There are probably only about 4 strands, but they are dark brown and really thick - about 5 micro metres. Wow. I have never seen fungi that good.

My conclusion is that the compost is "average". We need to add more fungal food to our compost. Obviously we have the capacity to produce some amazing fungi, but there is not enough food in there for the fungus to grow.
