Historically, many potato farms in the Manjimup-Pemberton area used a five year rotation of potatoes, hay, pasture, pasture, pasture.  Pasture species were generally limited to sub clovers and annual ryegrass species.  Soil health was declining on many of the farms in the area because potato production practices were and area very damaging to both the soil and soil biology.

Soil disturbance and organic matter removal from potato farming means that carbon is lost, soils form hardpans, pH becomes more acidic, nutrient and water retention reduce and weed burdens increase.  As an added insult potato pasture and hay yield and quality all decrease.  The loss of carbon reduces the soils’ capacity to function in so many important ways.
