BD 500 through 508. Jeevamrit. Panchgavya. Two ancient farming intelligences working together on one estate.
At Aura, biodynamic farming is a closed-loop operating system — a way of understanding the estate as a single organism where soil, plant, animal, and cosmos are connected.
We practise two systems simultaneously: European biodynamic and Vedic agricultural science (millennia older, orally transmitted, regionally adapted).
Two languages describing the same intelligence.
BD 500 — horn manure. Cow dung packed into a cow horn, buried over winter, exhumed in spring. The microbial transformation that occurs underground produces a concentrate of soil-building biology. Stirred dynamically for one hour — creating a vortex, breaking it, reversing — then applied to soil in the evening, when the earth is inhaling.
We will say the thing most of the biodynamic world talks around. The lunar charts and the talk of the earth breathing are poetry, and poetry has never survived a controlled trial. We keep these preparations for a harder reason: the biology in them works, we can measure it, and we do. The ritual earns its place by what it grows in the ground. That is the only test we let it take.
BD 500 — Horn manure.
BD 501 — Horn silica.
BD 502–507 — Compost preparations.
BD 508 — Horsetail.
Alongside those numbered preparations, the estate prepares and applies a parallel set of inputs rooted in Indian agricultural science —CPP, Jeevamrit, Panchgavya, Beejamrit, and older preparations from the Vrikshayurveda lineage.
The two systems reinforce each other. Each carries a piece of the same underlying observation: feed the soil, close the loop, and let the cow do most of the work.

We SCALE WISDOM. We keep what works, and build on it.
Everything begins with the cattle. The Malnad Giddaare the small indigenous cattle of these hills, grazing at this altitude for centuries. Their gut has adapted to the estate’s grasses and soil over generations, and the reasoning here is that the dung carries that adaptation with it. The comparison against another breed has not been run.
The dung drives BD 500, CPP, Jeevamrit, Panchgavya, and compost activation. The system tracks which animals contributed to which preparation batch. Ninety days after application, soil biology outcomes are cross-referenced with the preparation’s lab results — pH, EC, microbial colony counts, Trichoderma viability,Pseudomonas counts.
The cattle rotate through blocks timed to coffee cherry development stages. At the right time, their presence enriches soil biology for the next season. At the wrong time, it compacts the ground. Timing is everything. Right time, right action.
Every batch is tested before application. The BD application data stream records which crop layer was targeted, which blocks received the application, the lunar calendar day, the weather at the moment of spraying, the field worker, and the dung source batch. Every entry is cross-referenced with soil health outcomes over the following months.
pH and EC.
Microbial colony counts.
Compost maturity.
Heavy metals and pathogens.
AAT chromatography.
Spray teams.
Buffer days.
A full biodynamic year — every preparation applied, every batch tested, every block retested at ninety days — is written down as it happens and signed by the person who did it. The record is kept in plain JSON and CSV, readable without any of Aura’s own software.
Each entry sits alongside the weather at the hour, the point in the lunar calendar, and the soil result that followed it, so a claim about a block can be traced back to the batch that made it.
Every one of those milestones is signed and timestamped in the estate’s own record, which is what this page stands on. Writing them to a public chain is the next step, and when a lot page is open for anyone to check, it will be linked from here.
Biodynamic inputs, ecological pest balance, a restored soil microbiome — this is the estate working hand in hand with the land’s own intelligence. We believe it is the only kind of farming that will still make sense in a hundred years, and we are building as if we are right.
A four-story polyculture, fed by preparations from indigenous cattle, building soil carbon decade over decade. This is what a closed-loop operating system looks like when it has been running long enough to forget where it started.
