Mysterious Amazon soil (Bio-char) What is Terra Preta soil?

Terra Preta is often referred to as Amazon fertile/dark/black/super soil or Indian black earth. In Portuguese, it is known as Terra Preta do Indio. It’s a highly fertile anthropologic (man-made) soil specific to the Amazon region created by Amazonian civilizations approximately 7000 years ago. They may or may not have realized the significance of adding biochar to the soil had such a positive effect on crop yields. Terra Preta is still present today and is even being mined as potting soil for sale in local markets.
This “circular living system” where the inert elements provide the perfect conditions for the mycorrhizal fungi and microorganisms to thrive. These promote amazing soil health, which in turn drives better plant health and crop yield above the ground.
Terra Preta soils are very different from the surrounding tropical soils. These are notoriously thin and nutrient-poor containing high levels of clay, silt, or sand.
Color and composition
Terra Preta has a characteristic dark color due to the black carbon/charcoal/biochar content incorporated in it. For the purposes of today’s context, it would have contained partially burnt wood, charcoal, biochar, and ash. We will refer to this as biochar (see differences here). During recent sampling, it was found to contain local brown soil (Terra Mulata*), biochar, and shards of pottery.

That soil was definitely invented to fix the native infertile soil. It's so much ancient lost knowledge of there

[@litterbox2010]

It's not lost. It's composting.
We just keep telling ourselves ancient people were dumber than us. They clearly weren't.
People who garden sustainably, or anyone with an interest in environmental sciences/conservation know this 'lost knowledge'. No one listens.
When we tell you these things, how to do them and why, everyone gets all political and angry.

Heard about this years ago and started throwing my campfire ashes and charcoal ashes over the fence in the weeds. My ex was assured that grass wouldn’t grow under her tree in the front yard at her apartment. I fetched the soil and it was dark like the video. The grass really “took off” and ended up thick with deep green color.

[@Lobos222]

The main reasons is potassium and phosphor. While this is dark ages type fertilizing. We mine potash today, which is a mix of minerals, aka rocks. However as the name insinuates. It also has industrial history via burning wood and using the ash to accumulate the same content, but at a much lower rate than via minerals.

[@ach2lieber]

Interesting. And here we've been trained to throw out our fireplace ashes.

I’ve never been clear what purpose the shards of pottery serve in the terra preta.

[@spektrul4905]

To retain water

[@RelaxPlaya]

Ad keep it oxygenated

The micro pores make great homes for bacteria and nutrients.

Btoken pottery makes a great home for soil bacteria to thrive

One thing I know if soil is fertile if you found lots of earth worm in it.

[@RamblingWithRitchie]

Cheers for this video 👍🏻

[@PrepperAction]

Any time!

Fertility has an impact on color in plants. The Hawaiian drug patrol has a certain type of technology that can distinguish between levels of green in the leaves of plants. Could that technology or something similar be utilized to find patches of Terra Prata?

[@jdabseerl4016]

Just an opinion but maybe some kind of compost/ garbage system?

[@musskeeterbump]

would that technique work on Mars in Martian soil ?

[@ampsquadshorts]

Tell me I'm not alone who's has come here from podcast lol 😂
Salute to u brother for listening such good things in time of hell generation,tell me ur age in bw 🤝🏻

The Agni Hotra practice from India, which is taking off all over the world, has the reputation of converting barren land into fertile food forests and of healing all kinds of ailments of the human and animal bodies. It relies on mantra, specific timings, offerings of clarified butter to a fire and then spreading the ashes where needed. Not only do the ashes have cleansing effect, the practice itself cleanses and beautifies the atmosphere.

[@Slimenator]

There may be something to it

[@litterbox2010]

Native Indians? lmao
