Regenerative Agriculture

How manure becomes soil and returns to the pasture

Soil → grass → cow → milk → compost → soil again. Regenerative agriculture means keeping that loop unbroken.

The D2O HBP system

HBP stands for Humus Bedded Pack barn. It takes the CBP (Compost Bedded Pack) method — deep bedding tilled every day so that it composts inside the barn — and uses D2O Humus (peat moss) as the bedding material. That is D2O's system. No slurry pit is needed, and the cows live on a soft, dry floor.

It is in daily use at Song Young Shin Farm. By the farm's observation the bedding and manure mature to a soil-like state in about two months. Odor reduction and maturation speed are being measured under a field verification plan, and the results will be published together with the measurement conditions.

Tilling: Once a day; Our own records; Tractor today, robot in future
Maturation: About 2 months; Our own records; Farm observation; verification under way

Raised on grass

The Jerseys at Song Young Shin Farm eat hay. More than 80% of the ration is forage and no silage is fed. About 30 hectares of pasture and forage fields produce roughly half of the hay. Compost from the barn goes back to this land.

Compost becomes a product too

The farm's fermented compost reaches consumers as After Milk, a compost for house plants. The loop closes when someone who drank the milk grows a plant in soil that the same cow made.
