Okay, if you are faint hearted skip my contribution. I butcher at least 6 roosters yearly, catching blood in a bucket, keeping said bucket as a fetid fertilizer solution; in the winter, being in zone 5, I use a woodstove and take a little wood out before its fully burned, and crumble the charred wood into the blood bucket and let it fester all winter in the mud room where it won't freeze and break the bucket. My sandy soil has been pitiful, but where I amended the garden bed this spring with my fetid bloody char solution, I have had tremendously increased production.

That me think about my idea, which I brainstormed regarding the new proposed EPA regulations on meat processing facilities (they will have to have their own sewage treatment since they will be prohibited from contibuting to municipal sewage). I was thinking that they could partner with a co-op and offer the blood and entrails to be composted. This would greatly reduce the amount they would need to treat when they have to make the transition. But yeah, the same idea of animal waste compost but a bit different and on a larger scale. I think it would be a great idea. Don't know if it woukd ever be adopted, though.

one more data point: about 5 winters ago, any time something would go bad in the fridge, I chucked the remains onto one spot in the garden. Meat, veg, fruit, soups, rice, pasta...anything. The next summer I planted poblano peppers in that area. The plants were over 6 feet high, very strong (I never staked them) and super productive. I still have some of the poblano salsa and jelly from that year, there was a LOT. I have taken to throwing refrigerator compost directly into the garden during the winter. During the summer, it gets added to the compost pile.

The terra preta thing is fascinating. The pottery thing, in particular is interesting because it seems almost intentional technologically, but they couldn't KNOW about microbiology or the function that the porous pottery serves in the soil. That got me thinking. The common elements are char, ash, bones, small pottery shards. In lots of indigenous cultures, there's a cooking method involving pretty much any protein, leaf wrapper, and then a thick coating of wet clay, which is tossed directly into a fire to cook for several hours unattended. I've seen them drug out of the fire and cracked open and I've seen videos on YT where they get opened straight in the pit and the leaf package retrieved to the plate. It seems to me this type of cooking done at village scale solves a lot of communal issues as a kitchen initially might account for most of the ingredients and perhaps subsequent generations went on to use it as a communal trash pit. I like the idea that my barbecue pit may some day respawn paradise. Thanks for your books and videos, Dave.

That is an interesting idea. I had assumed that it was just due the poor quality pottery due to the poor quality clay available, but if they were effectively making pottery every time they cooked, and making extra charcoal by burying the fire for the roasting process, they could be generating the primary components unintentionally at an alarming rate.

When I want great soil I make it. A lot like what your doing. I layout a giant brush pile and burn to char. I cover the char with a 6 inch deep layer of wood chips. I cover wood chips with leaves and grass clippings and chicken manure to sit over winter,as im in northern Virginia. The bed should be ready to plant in spring. It basically a permaculture garden on top of bad soil that penetrates the bad with fungal shoots that break apart,yet hold together the soil and turning it the most perfect black , loomy soil! But,like you said,the Terra preta keeps self feeding for many years to come ,as to where you would have to put more manure on top if the garden is lacking. Every method has it's ups and downs. That's part of the beauty of gardening. PTP.. point to ponder... I noticed that I have a mycelium layer that is critical to long term self feeding process,but keeping the mycelium fed is an issue I solved by collecting all my lawn waste. I vacuum mow what grass i have left,and then go up and down the side of my road gathering hrass clippings and leaves. I pike extra for chickens to go through and they break most things down for me in a fraction of bio- waste time of natural process. Sorry I am rambling.

I built a kon tiki style fire pit in the ground to make charcoal for my biochar and just love it. All of my beds now have biochar in them you see if you grab a handful and they're a few years old so well aged. my greatest tip is to store up gallons of urine and use that as the initial quench, the steam will frack the nitrogen from the soil deep into the charcoal and no pathogens survive red hot coals. It's got a start on inoculation right from the start. After it's quenched with lots of water I'll add bokashi liquid, compost and leaf mold, bone meal, oatmeal (great for fungal growth), compost extract and tea, liquid JMS and anything else that's good. Between the biochar and compost my living soil cranks out amazing plants and honestly, they have little if any pest or disease pressure either.

What you're looking for is the most bioactive environment so that the soil can basically fertilize itself. I would introduce a secondary pit next to it converted into a pond. That way enough water can filter into the terra petra to keep it hydrated and bioactive. These rainforest soils had a huge amount of water in and around them. That's what you're missing most.

Rather, they probably thought something like, "We feed the earth with these things because the earth must eat to bear children. Where we place the most food is where the earth is most fed and can give birth to the most things." You can even see the symbolism in carving a deep trench. It's very mouthlike.

What could be interesting is adding vermiculture compost to the remaining product to see if the char material breaks down faster.

Native Americans are still making terra preta today. They sweep up ashes and coals and pile organic matter to let that compost and make the soil “strong”. I don’t think it’s a mystery any more. One factor to consider is the local soil chemistry of the Amazon basin. In general, studies show fresh organic matter composted on the native soil with fresh biochar selects a uniquely beneficial distribution of soil microorganisms by the graphite like carbon crystals facilitating electrochemical communication between species of said microorganisms. The other physical and chemical properties of biochar have been well characterized.

Just an assumption,I most definitely could be wrong.

The secret is pottery fragments holding water and charcoal filtering nutritions then creates medium for beneficial bacteria when leaves and organic matter fell inside continuously create more and more breaking down nutritions and filter up all that by carbons, that makes it perfect soil

I'd think of how it was first formed and do some science-based guess work. 1) The science. Charcoal has like twice the surface area of dirt. The reason is, it still has the channels that water traveled up the trunk to the top of the tree. It's porous. Because of the holes all throughout the material, it traps nutrients. So not only does it have surface-level nutrients, like dirt, it also traps nutrients directly. The more, the better. Clay is a slow absorber and releaser. That is great and it's required, but the soil already has to have a ton of nutrients for this to occur. Terra Preta has a unique microbial biosystem that has evolved for that type of soil. Knowing that, here's what I think but can pretty much guarantee what happened: Humans kept feces and nasty left over animal-based food parts and similar things away from their food in some form of dump. One day they noticed that a ton of stuff was growing really large and really fast near their dump and no where else. People like to grow food fast. So they decided to start growing stuff with the material from their dump. It worked. So the kept doing it. Terra Preta was not formed intentionally; it was a lucky coincidence. So what are the pieces that matter? A local fertilizer ecosystem. All of the waste was almost universally a product of what they were growing and what grew around the area. They were burning local trees and burning local waste produced by the consumption of local food being produced in the farm where they were going to use the waste. Terra Preta is the result of this process being repeated over at generations. So if you were going to recreate this process faster, you would most want: A ton of charcoal. You know that from the science. I would guess that you would such want to try to avoid one-off fertilizers that don't use the same bacteria that breaks down the plant waste of what you're growing. You want long term benefit, not short term, so you'd want to add mostly compost from what you intend to grow and have that be your fertilizer, and if possible, manure from animals whose diet is either what you're planning to grow, or at minimum, local plants. Not artificial foods. Anything else Is consider whether it's really required and would actually benefit, or if it's just a one-off fertilizer that will disappear as soon as it's used up by the plants. I think the localized bacteria colonization is an aspect oven overlooked. For fast forwarding your efforts, a small amount of Terra Preta might help because of the bacterial colonies, or it might not. It would probably depend on what you're growing and where. I would guess whatever is growing in it is suited to that type of soil, but at the end of the day, the ecosystem formed because it was local microbes feeding on local waste and plants over time. It will happen sometime either way, but maybe you'd get a lucky boost early on.

If Tera preta was just a burn pit for waste, why so much char? They must have purposely been using the char to absorb ordors or something, otherwise if they intended to just burn everything, there would be no char left. The creation and use of char must have been intentional. Perhaps they periodically covered their waste with it so it didn’t smell like a sewer.

Good luck. I think the best shot is to try and recreate Terra Preta in the Amazon first, where the temperatures, soils, humidity, precipitation, micro-organisms, etc are the same, and then once that's been done successfully, see if that can be transferred to other parts of the world. I also wonder how much Terra Preta is "created" and how much is "maintained"? Through regular additions of human and domesticated animal urine, food waste, etc.

a brick maker or a pot marker would see clay and charcoal fragments differently. If they are living in an area with a lot of clay - dig out some clay, kind of pound it thin, let it dry, and then when you make the fire, put the dry clay on top. the chemical reaction makes the new, dry clay parts great for drainage and all the other things that the wet clay wont do. maybe a big wood fire, and then all the other stuff like bone, and then layers of dry clay on top.

one thing I heard was a theory is that they burned it wet, kinda more of a boiling to break it down, and my theory which is probably wrong is that by burning it like that you lose less of the good stuff that comes of in the smoke which does take out nitrogen from the wood when you burn it.

I wonder if you really have to make the biochar as a separate process. I wonder if you could simply char or toast wood chips with one of those propane weeders. I know charring wood acts as a preservative, but I'm thinking if the chunks are small enough they would end up absorbing water and decomposing from the inside out. I think one of the biggest factors with this especially when it comes to clay soil is the increase in both aeration and moisture holding ability. Both of which allow living organisms to survive deeper into the soil. Burning the bones give you the same effect as adding lime since the bones break down into calcium carbonate which increases the alkalinity of the soil. Making clay soil more alkaline causes the tight bonds between particles to break down making it much less sticky when wet an far more friable when dry. I think the blackening of Terra Preta has less to do with the charcoal and more to do with the ability of organisms like worms lactic bacteria being able to thrive within the soil. I think making and adding Jeevamrut might increase the rate in which the soil blackens due to increased microbial activity. Just be careful where you get you cow poo since 2,4-d often sprayed on hay fields can still be found in the waste of the cows that consume it. I suspect this might be close to the missing key ingredient from your experiment since we know ancient civilizations separated urine from their solid waist. Liquid Jeevamrut is not only used as a fertilizer but also as a natural pesticide. I'm planning to make and try out Jeevamrut once I get some cows. My whole property is rocky hard clay soil with only about on inch at most of top soil covering it. I can add all the organic matter and compost I can source and it just burns off every year. Mulching helps to slow down the burn off, but it still never last more than a single year.

there's a few papers on microbial analysis of terra preta, some unique clades found, since it's said to "grow" there must be a living element to it, I've tried a few different applications with different "charges" cycling through compost seem the best, soaking in urine is not brilliant in the short term as I added it to a new bed planting beans in it which were covered in black fly within a week same plants in an established bed were not affected, maybe it was the urine more than the bio-char as John Kempf reckons a plant high in nitrates will attract pests, tho it's early days (2nd season) it's interesting stuff, following your experiments with interst, cheers David.

These are thoughts I have after watching the making and annual follow up videos: After the trench is dug, the sides and bottom can be lined with clay pre-burn so that a hardened clay barrier between the target volume and the surrounding soil is established-hopefully preventing native tree root invasion. Some considerations would be the temperature and longevity of the fire and how that impacts the curation period and efficiency of hardening the layer of clay-dependent upon its thickness. Some of the clay may also pop and shatter while firing because of expanding trapped moisture pockets. This clay barrier may also assist in nutrient retention Mixing in Amazonian terra preta introduces micro biome colonies sourced from ancient agricultural sites that may assist in soil longevity, soil life sustainability and micronutrient availability in the root space. These are just thoughts and not suggestions. Do with them what you will

I know the secrets of this soil. 😅 All soil is ammended by cycles of disturbance and rest. Now add flooding into the cycles and you've got the common denominator of every early agricultural culture 😅 These Terrapreta areas were like 50 acres in size. I think to clear jungle for towns they flooded areas along rivers for a time to kill vegetation, then drained them, and all kinds of weeds and grasses and saplings would pop up and a year or so after draining they would scorch it and move in. All the aquatic vegetation and minerals in the water would make it extremely fertile and they would live there for a few years and repeat all along these tributaries of the Amazon. They didn't have backhoes so there's no way they could have dug this fertility into the ground. 😂

@@davidthegood all these sites are along rivers. Of course because rivers are the only effective way to move through the jungle. Flooding is the only effective way to kill acres of trees.

My take on terra preta is its almost always found in groups. Makes me think Dakota fire hole design thats.always burning but little smoke. Intake side would be for garden scraps, bones, and the villages toilet... If smell got too intense burn wood for ash or clay to absorb the stink, I mean an entire village could fill quite the septic tank. They burned it, along with everything else. All that concentrated nitrogen from urine, bone meal, biochar, and human fertilizer built up over any amount of time while the hole filled would definitely be some of the best ground ever. How did villages full of people dispose of there own human waste while there's a big open burning pit in the ground?

Also Preta is for creating deep soil where its not good deep soil already. If you had happy root laden soil the difference wont be as big as if the soil is baked packed dead to begin with. Like my clay. I cant get water to soak in; my results will be bigger just for that teason alone.
