The Soil

Most of the ground is stony, which is one  of the factors of the quality. In Las Chas, for instance,the composition of the soil (down to 30 cms) is as follows:54% stone and gravel, 12,8% clay, 2,1% organic matter, 0,40% potassium. During the day the stones are heated by the sun, so that they give heat to the plant during the night (in this way tha maturing cycle is considerably increased).

The area of greatest slope, soil is more clay, herbs remain throughout the year to prevent erosion.
