Para caracterizar los suelos de los brezales húmedos atlánticos del norte de Galicia, dominados por la especie Erica mackayana, se estudiaron las propiedades físico-químicas y se caracterizó la materia orgánica en noventa parcelas de 18 sitios. El principal responsable de la nutrición de estos hábitats es una materia orgánica poco evolucionada a través de un intenso biorreciclado con un fuerte control local por condiciones microclimáticas y con poca relevancia de la naturaleza litológica. La capacidad de intercambio catiónico es baja y tiende a estar dominada por Al. En este contexto, el impacto del calentamiento climático y los cambios de uso del suelo sobre la evolución de la materia orgánica, así como la posibilidad de estabilización en compuestos organoalumínicos será el principal responsable de la evolución del sistema suelo-planta en este hábitat.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Heathlands are a habitat type with a close and complex relationship between plant communities dominated by evergreen shrub species and soils characterised by nutrient poverty and high organic matter content. To characterise the soils of the Atlantic wet heathlands of northern Galicia, dominated by the mackayana species, physico-chemical properties were studied and organic matter was characterised in ninety plots at 18 sites. The main responsible for the nutrition of these habitats is a poorly evolved organic matter through an intense biorecycling with a strong local control by microclimatic conditions and with little relevance of the lithological nature. Cation exchange capacity is low and tends to be saturated in Al. In this context, the impact of climate warming and land use changes on the evolution of organic matter, as well as the possibility of stabilisation in organoaluminic compounds will be mainly responsible for the evolution of the plant-soil system in this habitat.]]></p></abstract>
