Bedding, consulting and a robot in one — the D2O HBP system

D2O supplies D2O Humus (peat moss) bedding, advises farms converting to the HBP method, and is developing Galjeonguri, the robot that will take over daily tilling.

How the D2O HBP system flows

  1. Bedding

    Humus (peat moss) laid deep

    D2O Humus bedding

  2. Tilling

    Turned over daily to let air in

    Tractor → Galjeonguri

  3. Fermentation

    Manure composts inside the barn

    HBP consulting

  4. Compost

    Soil-like in about two months

  5. Pasture

    Back to the soil to grow grass

The D2O HBP system starts from CBP

A CBP (Compost Bedded Pack) barn has a wide, open resting area with no stalls, bedded deep and turned over every day to let air in. Manure mixes with the bedding and composts aerobically right in the barn. Cows lie down and get up freely, and no slurry pit is needed.

The D2O HBP (Humus Bedded Pack) system replaces the bedding material of CBP with humus. Humus (peat moss) holds a lot of moisture and binds odor compounds, so the system is designed to keep the floor dry, reduce odor and speed up composting.

  • Bedding — D2O Humus (peat moss) bedding
  • Design and operation — HBP consulting
  • Tilling — a tractor today, the Galjeonguri autonomous robot in future

D2O Humus (peat moss) bedding

We supply D2O Humus for barn bedding. It replaces sawdust or is blended with it, and we advise on the quantity and top-up interval for the barn area and herd size.

Used bedding matures inside the barn and comes out as compost. By observation at Song Young Shin Farm it reaches a soil-like state in about two months.

HBP system consulting

Changing the bedding alone does not make an HBP barn. Barn structure, ventilation, stocking density and tilling all have to fit for fermentation to hold. D2O draws up a conversion plan for each farm from its own experience running the system at Song Young Shin Farm.

  • Barn assessment — area, herd size, ventilation, floor condition
  • Starting the pack — depth, humus blend, moisture targets
  • Tilling management — frequency, depth, equipment
  • Operator training and follow-up checks
  • Using the compost — returning it to pasture and crop farms

When Galjeonguri is added

The most labor-intensive part of HBP is the daily tilling. Galjeonguri is a robot that drives itself and does that job. With the robot added to bedding and consulting, the barn keeps fermenting without someone climbing onto a tractor every day.

It is being developed under a Ministry of Trade, Industry and Energy project with GMW Co. and the Chungnam National University industry-academic foundation. D2O runs the field trial at Song Young Shin Farm and handles roll-out and training.
