Soils
Deep Andisol (>80 cm) formed by alteration of eolic ashes, covering Acrisol. Fertility is excellent but with high P sequestration. The loamy texture, halloysite contents as well as dryness of the soil after its agricultural preparation, generate crusting, especially after heavy rains. The C contains is high, but lower as expected and it is due to the erosion of the top soil.
