For farmers & FPOs

What taking part involves, before you agree to anything.

We work with smallholders. The rock has to fit a season you already farm, and the soil results come back to you — in Hindi, in the format of the card you already know.

An elderly farmer in a white dhoti and headscarf walking a grass field boundary with a younger field worker carrying a notebook, the farmer pointing across a newly sown plot as they talk; a tall green crop stands on the other side of the path and trees line the horizon.

Step by step

What happens, in order.

Nothing is spread on a field before its soil has been sampled and your consent recorded.

  1. A conversation

    Tell us your district and your crop. We explain the work, and whether land like yours is likely to suit it.

    District · crop

  2. Your consent, recorded

    Consent is recorded for each purpose, versioned, and can be withdrawn. Data about Indian farmers is stored in India.

    DPDP Act, 2023

  3. A field visit

    The team walks the plot with you and records its boundaries, so every later sample can be tied to the same ground.

    Plot recorded

  4. Baseline soil samples

    Soil is sampled at two depths before anything is applied. This is the before-picture every later result is compared with.

  5. Basalt, in your season

    Crushed basalt that has passed trace-metal testing is spread at agronomic rates, in a window your cropping calendar already has.

  6. A soil health card, every season

    Your results come back in Hindi, in the Government of India format, with last season beside this one.

What you get back

A result you can use on the field.

The same soil sample serves two purposes. The card on the left is yours. The panel on the right is the extra analysis used for carbon accounting.

Said plainly

What we will not promise.

  • A yield increase

    We report soil chemistry, which we measure. We do not put a yield figure on the basalt without a trial designed to show it.

  • That every field suits it

    In some soils the benefit is small, or the change is hard to measure. If that is true of your land, we will tell you.

  • That the rock needs no checking

    Basalt carries trace metals. Every lot is tested before it is used, lots outside threshold are refused, and the same metals are tracked in your soil afterwards.

Farmers & farmer producer organisations

Tell us the district and the crop.

Individual growers, cooperatives and FPOs can write to the same address. Someone from the field team will reply.
