About Sona Ugao

Sona Ugao is Arcus Serves Foundation's biochar initiative. It turns the crop residue that would otherwise be burned into biochar, made in the village with small kilns, and returns it to the same fields. The soil holds more water and nutrients, the carbon stays in the ground where it is measured, and the capability stays with the farmers who run it.

FROM STRAW
TO SOIL

01. Learning from working units

Understanding how existing units run before designing a kiln a village can operate itself.

02. Biochar, ready for the field

Rice straw carbonised into a stable, porous char that holds water and nutrients in the soil.

03. Bagged and delivered

Four tonnes packed and carried to the farms, village by village.

04. Handover at the farm

Each treatment plot is marked and matched to a control plot on the same farm.

05. Enrolment, signed at the farm

Plot details, inputs and practices recorded so results can be measured, not guessed.

06. Broadcast and worked in

Biochar spread and incorporated ahead of transplanting, following the recommended practice.

Signs from the field

Early season, and the treated plots already read differently.

  • Faster plant growth
  • Dense cropstands and leaves
  • Greener, brighter foliage
