TRENCHING INTO THE SOIL:
Ideally plan your garden in order to have an area clear of growing plants. Dig a shallow trench 30cm or so in depth and width depending on amount of waste. Place your fermented food waste into the trench and mix some soil through the food in order to increase the diversity of soil microbes in the waste.
Cover over a depth of 25 50cm of soil over the top, to allow the food waste to break down. Your fermented waste should barely be recognisable after 4 weeks. This process will take a little longer over the colder months. An area as small as little as a few square metres is all that is needed. You can continue to build the soil up with continuous applications of fermented waste until you are ready to plant.
Once plants are growing you can dig your fermented food waste in between rows of plants or around plants or shrubs. Try to avoid direct contact with plant roots.
Planting can take place over or directly into the fermented waste once 7-10 days has passed.
Remember: The `juice’ from ZingBokashi Compost Zing Systems is “liquid gold” for your garden. Apply with water, for bare soil application dilute 1:100, for foliar applications dilute 1:1000.
Mixing with Green Waste into a Compost Pile:
If available space is at a premium, and trenching in your fermented waste becomes difficult you can either use.
1. The Vertex Composta or
2. A traditional Compost Heap.
The Vertex Composta
This is an enclosed type of plastic compost container made by Vertex Plastics.
Trials carried out by the Strickland Street Community Gardens in Christchurch found that the Vertex `Composta’ was one of the best compost bins suited for the processing of Bokashi fermented food waste.
Simply layer your fermented food waste together with good quality compost/green waste or soil until such time your’ Composta’ is fill and then spread out over your garden when suitable.
The `Composta’ has advantages in that it has a good fitting lid and being lightweight is easily transported. Plus it can easily be lifted off the pile you have built inside and placed to a new position for you to continue using [see photo]
This method is ideal when garden space is at a premium or can be used over the winter months when weather conditions do not favour digging of the soil.
Tip: Retain some of this compost material and use it to cover your fermented food waste when you start again.
The second method of using your fermented food waste is to incorporate it into a compost heap.
As you generate some garden green waste this can be formed into a pile and mixed with your fermented food waste. The fermented food waste should be mixed with the green waste at a ratio of between 1 part to 5 (1:5) to 1 part to 10 (1:10). Mix this into the centre of your compost pile keeping an outer layer of green waste as protection.
It is best if you can keep the heap covered between uses
