Trench composting or Dig and forget composting

I will be honest. I love gardening but not a big fan of back breaking labor. The idea of having to turn compost and harvesting it does not appeal to me. Saving as much kitchen waste like chicken bones from landfill as I can however, does appeal to me. 

My mother, back in the days when we went fishing, used to bury fish scraps in the garden which turned into rich, fertile soil. Further research on the interwebs told me that you can bury your kitchen scraps directly in the garden, including chicken bones. Trench composting, direct composting, dig and drop composting whatever you want to call it, suits me. You don't have to turn the compost, harvest it or worry about carbon and nitrogen balance. The compost goes directly where you think it is needed, or in my case where you haven't dug compost in before. And the best thing is that you don't to worry about nitrogen and carbon balance and you can compost fish and chicken bones.

Since I started what I like to call dig and forget composting I've noticed more worms and the time it takes for the kitchen scraps to 'disappear' is faster - in summer it can be as fast as 2 weeks for vegetable and fruit to compost. All that is left of the bucket of chicken bones I buried in one corner of the garden seven months ago is a handful of bone fragments. That tells me that I have healthy soil full of worms and microbes.



This is the depth you should dig and forget compost.

I dig and drop one bucket (I think it is 20 litres) from my parents place, two buckets if I felt like cooking, once a week. Make sure you dig a hole that is at least 30cm deep so that animals don't dig up the scraps. And mark where you buried the compost. The soil drops as the scraps decompose. The number of times I have forgotten and my foot has sunk into the compost hole.

What goes into the compost bucket? Pretty much everything - citrus peel, chicken bones (I debone chicken wings and thigh cutlets), spoiled dairy products, spoiled food - my sister saves prawn shells to put in the compost bucket for me. I even have a bucket at work that people put their fruit scraps and used coffee pods in.



Make sure you put any fish,prawns and chicken bones at the bottom of the hole. I freeze these scraps as I can only get to my plots on the weekend.



The rest of the compost bucket is dumped on top of any prawn, fish and chicken bones. When I rinse out the compost bucket I throw the water into the hole before I cover the compost with soil. I give the soil a quick water and hope that I don't dig it all up again when I dig my next compost hole.
