The main factor influencing the soil drainage is the texture. Ideal for the vine is a medium textured soil (clay and sand
balanced).
A well-drained land is critical to raising the quality of wine grapes. To do this, besides medium texture is important
the soil is deep. Shallow soils are not recommended for any vineyard. The vine has roots aprofundantes. Are
long and have room to expand. At least 60cm deep. Less than that compromises the fixation
vine, depending on which there underneath, fruit quality and health of the plant. If stones there is a risk, in times
drought, the plant go without water. If it is a water table, the level of sugar in the fruit can be seriously compromised.
In addition to organic materials produced by photosynthesis, the vine needs a complement extracted from the soil. Materials
organic substances present in soil have stabilizing function. Affect the permeability of the soil and imply increased productivity.
The addition of organic material to the clay soil becomes more permeable, ie, it increases its porosity, and amazing
it seems, the added organic matter to sandy soils acts in the opposite way. Decreases the pore size and
therefore impermeability. Normally sandy soils require more fertilizer than organic clay.
The first thing to do before planting any kind of vine is to examine these soil characteristics.
