Woodhaven Vineyard soil structure

Woodhaven Vineyard is nestled in the low rolling hills of Red Hill on a north facing slope of red volcanic clay/loam known as the Red Hill tertiary basalts.

The dominant soils of the Woodhaven Vineyard are red ferrosols; high free iron oxide content.  The sub-soil is yellowish red, medium to heavy clay.  Once vines are well established on the Red Hill soils, there is no need for supplementary water. Accordingly, the vines are dry-grown to concentrate fruit flavours in the grapes.  

We work to increase the soil organic matter by applying compost and mulches and biodynamic applications which increase the microflora in the soil and enhance the symbiotic relationship of the vine roots with the micro-organisms in the surrounding soil.   We add Gypsum under the vines to facilitate the natural uptake of required nutrients by the vines. No other fertilisers are added to the soil. 

Clover and grass cover in the vineyard cools the ground, fixes Nitrogen from the air, and traps moisture from dew.  A diverse mix of plants around the vines protects the soil and encourages beneficial insects.
