Natural Park soils are generally poor, somewhat acidic and poorly developed. The main soils are displayed Leptosols, Cambisols and Regosols:
Leptosols soils are generally poorly developed and a simple sequence of horizons metamorfosedimentarias grow on rocks. The term comes from the Greek leptosol "leptos" meaning thin.
are defined as natural soils, minerals that are not permanently frozen and are limited by a continuous rock within 25 cm of the surface, or by a material with more than 40% of calcium carbonate equivalent. Also considered as such to those in their first 75 cm only have less than 10% of components under 2 mm. In any case one can have a mollic surface horizon, or ochric umbric and in depth only one or vertic yermic.
The main factor limiting the use of these soils is its small thickness, although associated with it have poor water holding capacity, making them very dry soils under xeric conditions.
Leptosols and Dystric Lithic and their associations representing 28.67% of the area of \u200b\u200bNatural Park, while their associations with other soils are represented in space 31.91% protected. The Cambisols have
horizons, having a distinct B horizon, usually richer in depth than the previous soil. Cambisol The term derives from the Latin word "cambiare" which means change, referring to the principle of differentiation of horizons indicated by changes in color, structure, or the laundering of carbonates, among others.
The Cambisols are developed on altering material from a wide range of rocks, among them the nature wind deposits, alluvial or colluvial.

allow a wide range of possible agricultural uses. Its main limitations are related to topography, thin, rocky, or low in bases. In areas of steep and its use is limited to forest or pasture.
The Cambisols alone do not have excessive weight (3.45% Natural Park), but their associations with Regosols and Leptosols (13.35% of protected area). Regosol The term derives from the Greek word "Rheged" meaning sheet, making allusion to the mantle of change that covers the earth.
Regosols develop on unconsolidated materials, altered and fine texture.
appear in all climatic zones without permafrost and any altitude. They are very common in arid areas in the dry tropics and in mountainous regions.
The AC-type profile. There is no one diagnostic horizon except a superficial ochric. The evolution of the profile is minimal because of their youth, or a slow process of formacioón by a prolonged drought.
Its use and management have varied widely. Irrigated support a wide variety of applications, while low load extensive grazing are the main use. In mountainous areas it is preferable to keep them under forest.
In the Park, Regosols are characterized by very dense, acidic in nature and organic matter accumulation on the surface. Appear on the slopes of the valleys. The associations of these soils with the above are important in this natural area (6.05% of its surface).
The Fluvisols, although unimportant in surface soils rich are related to the courses of major rivers in the Natural Park, which appear naturally associated riparian forests. However, they have a good agricultural suitability that has been exploited by man. Displayed without forming associations and the Natural Park not exceed 1.2% surface (Fluvisols eutric). Fluvisol The term derives from the Latin word "Fluvius" which means river, hinting that these soils are developed on alluvial deposits.

type of profile BC with clear evidence of stratification that hinder the differentiation of horizons, but often the presence of a Ah horizon conspicuous. The redoximorphic features are common, especially in the lower profile.
The Fluvisols often used for food crops, orchards and often grazing. It is usual that require flood control, drainage, artificial and are used under irrigation. When drained, the Fluvisols Thionic suffer a strong acidification accompanied by high levels of aluminum.
The remaining soils listed are unimportant in the Natural Park, with the above, along with their associations, that showcase the pedology of this protected area.
