dc.description.abstract[EN]: Native pastures of the upper zones of the Guadalquivir river marshes (vetas), have a noticeable nutritive value with N, S, P, K, Na, Ca, Fe, Mn, Zn, Cu, K/Na, Ca/P, K/Ca + Mg and DDM/levels adequate, in general, for the indigenous cattle requirements. In these zones, tbe salinily level is comparatively low in the top layer after rainy periods and the useful water level comparalively high, improving so the herbage production. In general, physical properties of the soils of the Guadalquivir river marshes are typical of heavy clay soils, that facililates the soil contaminauon of herbage.es_ES
dc.description.abstract[FR]: Le pâturage naturel du marais haut du Guadalquivir (vetas) a une valeur nutritive notable, avec des niveaux de N, S, P, K, Na, Ca, Fe, Mn, Zn, Cu, K/Na, Ca/P, K/Ca + Mg et DDM suffisants pour les besoins du bétail autochtone. Ces zones ont un bas niveau de salinité dans l'horizon superficiel après les périodes pluvieuses et un haut niveau d'eau utile qui facilite la production herbacée. En général, les propriétés physiques des sols du Marais du Guadalquivir correspondent à celles des sols argileux, ce qui favorise la contamination du pâturage par le sol.es_ES
