Aerating compost

Want to turn your compost into rich organic matter for the garden, quick smart? Get air in there!

Aerating your compost will help to create the ideal conditions for rapid breakdown of your organic waste.
Healthy compost is full of millions of insects and aerobic bacteria that break down the organic matter.

Like us, compost critters need air to breathe. Compost that is aerated will produce rich compost five times faster than organic waste that’s left to decompose on its own.

The most crucial reason to encourage air into your compost is that without it, ‘bad’ bacteria will take over and your compost system will rot. Rotting compost not only smells, but creates methane gas, which is 21 times more potent a greenhouse gas than carbon dioxide.

There are a number of ways to add air to your compost. You can dig into and turn your compost with a garden fork or shovel. Pipes with holes along their length can bring air into the lower levels of your compost. Tunnelling holes into your compost will also help to bring in air.

A compost aerator is a quick, easy and effective tool to use. Insert it into your compost and twist in several places to break down and bring air to your compost. An aerator can also bring rich compost from the bottom of your bin to the top, ready for use in your garden.

For your compost to thrive it needs ADAM; Aliveness, Diversity, Air, and Moisture.

Why is my bokashi bin not producing liquid?

Sun, 29 Aug 2021 03:30:24 GMT

A common question I get asked is "why is my bokashi bin not producing liquid?"

The answer is simple.

The juice will really depend on how wet the ingredients are. If you are putting in things with a high moisture content, like watermelon, tea pot washings, fruit, then a lot of liquid will break down from it. If you are putting in drier things like rice, meat offcuts, carrots etc, then they have much lower moisture content.
You can compact all the ingredients down with something like a potato masher to squeeze out any liquid, and I highly recommend rinsing your tea leaves/coffee grinds into it to run it a bit wetter if you want to get some liquid probiotic to then water down and use on the garden.

Here's a great little clip on decanting and diluting your liquid once you make enough.

Sustainability boredom busters

During these uncertain times, many of us are juggling working from home with kids needing stimulation. We are in the process of putting together some activities and resources sto keep the little ones (and not so little ones) entertained, I have put together some resources from other organisations that I found excellent!

Cool mob Australia has developed some fabulous resources for younger kids. Click on the images below to go to the respective activities.

Why garden shows are killing our soil

Fri, 15 Jun 2018 05:24:33 GMT

I get it.

Building a raised garden bed can be a bit of a hassle. You need crazy amounts of soil, compost, manure, straw, newspaper and any other organic deliciousness that takes your fancy. But what if you don't have enough? What can you fill it with that's free, won't break down (much), light weight, and considered "safe" enough to be used in the food industry?

This horrible stuff:

At least, that's what tv garden shows, blogs, and so called gurus would have you do.

via GIPHY

I've lost count of the number of TV programs, blogs, articles and You Tube videos I've seen promoting using this common pollutant as a soil filler. It makes me angry, as it shows a lack of corporate, social or environmental responsibility.

Furthermore it makes me angry that we, the sheeple, blindly follow these "great ideas" without question for the environmental ramification and long term impacts, not to mention the health consequences.

It concerns me that one of the most common questions I get is “Can I put bones or egg shells in my soil, as they take so long to break down?” Yet no one ever questions polystyrene, and gardening shows promote it! Why?

But before I show you the obvious eco alternative, let's dig a little deeper.

What we know about expanded polystyrene (EPS)...

It doesn’t decompose, just degrades into smaller pieces
Persists in the environment for 100 to 1 million years depending on environmental conditions.
It is banned in many parts of the world for use takeaway packaging including China, Zimbabwe, India, Taiwan and parts of the US.
It doesn't grow mould or bacteria – the opposite of organic matter like compost
It is ingested by marine and aquatic animals, clogging their digestive system, creating buoyancy that limits their ability to hunt, feed or escape predators, and ultimately kills them.
It can leach the toxins Styrene and Benzene (both suspected carcinogens, and known neurotoxins) into the environment and your blood stream
Polystyrene has been known to be manufactured with hydrocarbons and Chlorofluorocarbons (CFCs) with significant global warming potential (1000 times more potent than CO2)
Contains brominated flame retardants
The styrene monomer (from which polystyrene is made) is a cancer suspect agent.
Can interact with carotene (Vitamin A) or cooking oils
The National Human Adipose Tissue Survey identified Styrene residues in 100% of all samples of human fat tissue taken in the US.

A major manufacturer of polystyrene is the Dow Chemical Company, one of the companies that brought you:

plutonium triggers for hydrogen bombs,
radioactive waste leakage,
napalm and
Agent Orange.

via GIPHY

Let’s dig a little deeper…

There are two ways that polystyrene degrades: photodegradation and leaching.

Photodegradation occurs when polystyrene is exposed to sunlight for an extended period of time. Polystyrene starts to break apart into smaller, powdery pieces, becoming a micro plastic. Micro plastics act as a magnet for other pollutants such as heavy metals, and once in the form of a micro plastic, are near impossible to remove from the environment.

Do you really want to grow your vegetables in this?

Leaching occurs when the plastic becomes exposed to a certain amount of heat – such as that of a compost system. Under these conditions, tiny amounts of styrene can seep out of the plastic and contaminate the surrounding soil and water.

Meanwhile in Australia...

We are throwing out corks.

Hundreds of thousands of corks.

Straight to landfill. Do not pass go; do not collect $200.

See, the cork recycling industry in Australia just, kind of, stopped. Once recycling an item is not economically viable, it just doesn't happen. Cork recycling in Australia ceased around 2014.

But just because there is no recycling, does not mean there should be no reuse.

Instead of polluting our soil with polystyrene, why not use a natural product that is also lightweight, buoyant, water repellent, naturally fire retardant, and at the same time low emissions, non toxic, and organic?

So the million dollar question...

Where do you get enough corks to bolster up soil volume?

With no cork recycling programs currently in Australia, the best option is to partner with a local Community Garden or community group and start up a collection.

Chooktopia has been stockpiling corks for a couple of years now to trial uses including soil additives, concrete aggregate, gabion walls, retaining wall drainage substrate, insulation and more. Chooktopia is happy to share any excess.

Remember: polystyrene may break up, but it will never break down. It has no place in the natural environment.

Why are my worms all in the drip tray?

Wed, 16 Dec 2015 10:10:25 GMT

Worms are instinctive creatures, and they don't lose that instinct once they are in a worm farm.
In nature, their instinct helps them survive, but in a worm farm, that same instinct can get them into a lot of trouble!
Why worms head down into the drip tray:

Escape from heat
Protection from predators
Prevent drying out

What they didn't count on was the underground lake (drip tray)!
Worms aren't particularly good swimmers with their lack of limbs and life jackets. When they get down into the drip tray it can spell disaster.
It is best to leave the tap open so that the underground lake is more of a puddle, giving your worms the best chance of survival.
In summer you may even need to do rescue missions to get the worms out of the drip tray and back up into the farm. In particularly hot weather, freeze some of your food scraps before putting them in the worm farm. The worms will then move towards or away from the frozen scraps to regulate their temperature.
