Very confused now.
I just posted this on the new Tera preta website in response to a question but thought you might like to read it here too
Still procastinating about writing my TP article
Home Made Terra Preta (Nova?) Kit

Great definition erich
I have been mucking around with different potting mixes. with different %s of the following . I do much of it by "feel" or instinct as I have been growing plants in pots for 40 years. Always looking for "The Perfect Potting Mix"
I can't find broken terracotta clay so I use bentonite or attapultite as it is cheap and readily available.(kitty litter.).
I am told zeolite would also work well. I do like to use Terracotta Pots when I can.
Charcoal, very fine, in amounts from 5% to10% (I would use more up to 20% if I could afford it)
Down the bottom of the pot I put some seaweed (whole), horse manure fine, and fine chicken manure. I cover this with Very cheap potting mix then I add the clay and charcoal and more potting mix (I don't want young plant roots touching raw manure)
I use also a little slow release fertiliser and Miracle Grow Liquid fertiliser (small amounts often-the basil seems to especially like this)
Most plants and worms seem to love the "Terra Preta (Nova?)" thus made
Things I am leaving out shells, (have found a small local midden and may try this soon) fish fertiliser (too expensive), soil (too many weed seeds and poor PH) , quartz ( too hard) microorganisms.(too mean to buy them)-
The mix is a little heaver than I would like. Some sand, bigger bits of charcoal or silica might help. I notice there is a new Kitty Litter on the market that looks like silica but I wish they would put the full name of the product on the packet for
Strange Gardening Experiments by
Strange Gardeners. Replicating the pottery shard side of terra preta is difficult.
I am most proud of my one year old Fig tree (from cutting) that is now over a metre tall and has figs friuts/flowers? coming !
One thing that Terra preta does do for you, is give you a new appreciation of the complex web of life in the soil
I have a huge compost pile mainly of seaweed, have taken to emptying the vacuum cleaner bag on plants (As S. American Indians keep home floor sweepings for the garden) and now keep and grind up egg shells in a M&P for my 1 lavender plant. Even the ham leg from Christmas I gave to the crabs down the lake to clean. I have now retrieved it and trying to work out away of pulverising it!!
I noticed yesterday some locals putting lawn clippings in the council green waste bin.
I had to control my urge to run over and tell them not to throw away such good organic matter. It was not easy.
