📖 The Nature’s Lost Vault Book Is Now Available. Learn more: https://naturelostvault.com/book.html
Every morning, you crack an egg and throw the shell away. For centuries, farmers across Korea and Japan knew that shell held something your garden desperately needs, and that the chemical industry would eventually sell back to you for billions.
This is the story of Cho Han Kyu, a Korean farmer who watched his neighbors go into debt buying synthetic fertilizer for soil that had fed families for generations without it. What he remembered from the old ways became one of the most powerful closed-loop farming systems ever documented. No purchases required. No annual inputs. Just what the kitchen already gives you.
The calcium your plants need most is not missing from your life. It is sitting in your trash. Locked inside a form the plant cannot use — and one jar of vinegar away from becoming the most bioavailable soil amendment you have ever applied. What changed was not the chemistry. What changed was who profited from making you forget it existed.
Industrial calcium nitrate is now a 14-billion-dollar market. The USDA extension system that expanded after World War II was aligned with the chemical companies that built it. Farmers were trained to buy what they once made. This vault opens that door back up.

OMG I needed that tip a couple of years ago 🤣 I knew what my pepper plants needed I just didn't know how to fix it… I skipped a couple of years but I am giving it another go this year and have a new strategy to try and a dozen or so baby plants that I can try this on 👌🏻
I use my chickens egg shells to feed my garden, and also dry them and crush them for my chickens if I am short on oyster shell. Between goat and chicken poop, soaked weeds, egg shells, vegetable and fruit scraps, coffee and tea leftovers as well as used grounds I have a full aray of fertilizers at my fingertips for a wonderful compost or pour on liquid fertilizer. I also use the whey leftover from my cheesemaking, pasta and rice water, and soaked potato skins after eating potatoes out of our garden harvest. God gave us everything we need.
Common farming practice is to have fields "limed" before planting. Usually done sometime before planting to add calcium to the soil. The soil is tested to determine the pH level and know how much lime is needed.
I don't have eggshells in my household.
Sooooo compost.
Well, they used a lot more poudrette, composted barn sweepings, deep-rooted mineral miners like comfrey, green manure cover crops, wood ashes, and straw than vinegar and eggshells. Now, that's a real closed loop that modern organic gardeners/farmers use quite nicely..
Great video! I love the explicit instructions.
Thank you! 🙏🏼💚
The soil where I live is mostly red clay, which means iron content. Would calcium like this help the soil?
The prosperity of primitive farming techniques has nothing to do with egg shells. How many chickens does he think there are? The prosperity came from composting the plants and human waste back into the land. It was a closed cycle that lost no minerals. Today most of the waste plant material is fed to animals, and little of the human and animal waste is returned to the fields.
Love your channel. I learn so much. Many Thanks!!
This is excellent video , clearly step by step advice. Thanks
Stinking Rockefeller again
Thank you. I have plenty of eggs and never knew this. Now I will split my eggs between this and feeding back to the hens.
Have you done any videos about Azolla, the nitrogen fixing aquatic fern that helps fertilize rice paddies?
We’ve always saved egg shells. They’d be put into the oven after a meal was cooked and the oven turned off. They’d be then ground into dust and tiny pieces and fed back to the chickens. The chickens yard was last year’s vegetable garden and would be next years garden. The chickens never gave weak shelled eggs and the garden was always fertile.
Thank you for spreading the gospel of truth. The truth will always find a way to surface.
I find it hard to see eggshells providing enough calcium for large crop production. Where else can you get calcium from?
ThankYou ❗️❣️❗️
So with this knowledge now, how many egg shells per hectare? I'm not sure I could eat enough eggs for the 1000 ac's of market garden. Fair enough you could use it on a home garden, but to use the conspiracy theory your alluring to is a bit of a stretch.
Aricept does not work (ref my mother).
But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and for ever. Amen.
2 Peter 3:18 KJV
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
John 3:16 KJV
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
John 14:6 KJV
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
2 Corinthians 5:21 KJV
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Romans 10:9 KJV
I don't think everyone should use egg shells for calcium to plants, they are much better abundant calcium available in rock dust which can be added to a forest soil microbes culture and broadcast it to the soil which can fulfill calcium and other minerals to the plants by these microbes once they ferment and decompose them
Is this good for other plants also or just vegetables? What about using other food scraps to mix in for additional fertilizer?
Does the type of vinegar matter? We usually have raw apple cider vinegar in the house.
`The problem is scale…
Thank you for this. I've been looking for a chemical free solution.
Does anyone know impact of Apeel on composting pilrs? Stuff like that is on alot of store veggors n fruits now…..?
OK, what about bones? especially after making soap stock. Here in Southern California, the best Japanese gardeners used to throw blood or bone or fish meal handfulls around every week. Bones have both calcium and phosphorus , plus other trace. The other needed item is potassium. The irrigation water supplies sodium (as a carbonate), sulfur is usually in excess.
Is the wood ash of use for gardening. Sure lye soap, water purification, pottery, but gardening? (got plenty ash from the Barbeque). Note also that ash is certainly not flammable so can be used as insulation where it stays dry. Nitrogen in soluble form is needed- readily available from the obvious, unmentionable source.
I can't remember the author , but a good book to read is , The Secret Life of Plants .
