Soil Preparation Flashcards
Which elements of the soil does the grape grower need to make sure is suitable for planting vines?
Drainage and structure
Mineral composition
Presence of pests/unwanted animals
What does the structure of the soil influence?
Root penetration
Water drainage
Nutrient holding capacity
Workability
How does the gg prepare the soil?
-Big rocks may need to be removed
-Plough pan may need to be removed. (By subsoiling= better drainage and makes soil easier to cultivate)
-Roots must be burnt or can harbour disease
-Manure, compost, fertilisers applied to increase nutrients and organic matter in soil.
Ploughing, adjust PH (acidic soils eg in Beaujolais- lime sprayed then ploughed in).
Topography- steep slopes in Duero Valley- tuned into terraces= flat land
