Thought you might be interested in how we make fert?
Huge wall of text, but might be worth a look.
Picture 1.
We started with a 500l rainwater tank with a well fitting lid. I Made a giant "sock" out of 6 layer of shade cloth. The sock is twice as deep as the tank so it bunches up in the bottom heaps. That means there about a foot of scrunched up shade cloth in the bottom of the tank as filtration and a much larger surface area for the bacteria and yeast to grow on. Surface area is very important with this system as is the right "starter culture". If you get a build up of the wrong bacteria, the tank stagnates the culture dies and the stink is incredible!
Picture 2.
By volume, we aim for about 40% water, 40% fresh green weeds/lawn clippings, 5% ash from the fire(increases alkalinity, if you dont have ash a bit of lime will help every now and then) 10% roadkill/fish/meat/bones/eggshells/other and 5% household compost like citrus peel, tea bags, paper, fruit and vegie scraps/onions/rotten food/whatever else you find laying around.... Oh yeah, that skippy in the pic was a victim of the local roads, not by me by the way. I figured why let it go to waste, so I tied it to the roof racks an brought it home for the tank. Worked so well I do pretty often now.
Picture 3.
We drain the tank of half its fluid content daily and dilute it 1part "Juice"(think of it like a tonic not a fertilizer, like "worm wee"or "seaweed/fish emulsion") to 4-5parts water and use it sparingly on the garden. As the bacteria count can occasionally be quite high, only water on the roots of plants, and never on plants you will be harvesting with in a couple months. The sludge/soil/mud in the bottom of the tank can be shoveled out every 3-6months and is a great base for raised garden beds. Just layer cardboard then sludge, cardboard, sludge, cardboard, then good topsoil and plant into that. The cardboard and sludge layers really give plants a boost when the roots finally work there way down into them, and that's when they need it too, as they are nice and big by that time. The layering really helps maintain moisture levels too. The cardboard is free(love free!) and adds humus which is really lacking in our dry rocky soil. The high nitrogen, and trace element content from the sludge speeds up the cardboards decomposition.
The bones and feathers you see in the trolley are really soft like wet chalk, and if you were really keen you could crush them up with the shovel. I don't bother as they will be buried anyway, and with in another couple months underground, there won't be anything left at all, except an awesome garden!
