Abstract
El abandono de las tierra de cultivo constituye un procesos de cambio de uso del suelo que puede conducir a la regeneración natural de los suelos y la cubierta vegetal Sin embargo, las tierras abandonadas presentan diversas respuestas que dependen del tiempo transcurrido desde el abandono, características del sitio, posibles perturbaciones post-abandono, gestión previa y posterior, condiciones climáticas, etc., que condicionan la sucesión vegetal y las propiedades edáficas dando lugar a ecosistemas y paisajes tan contrastados como bosques, matorrales, pastizales y suelos casi desnudos, que experimentan cambios a diferente ritmo temporal (Lasanta et al., 2021). En este contexto se desarrolla la presente tesis doctoral que se centra en la evolución de las propiedades del suelo que se han visto alteradas como consecuencia de la degradación asociada al uso agrícola (viñedo), y la progresiva influencia de la recolonización vegetal y de la recuperación del suelo a lo largo de una cronosecuencia de abandono de más de 50 años. El estudio se realiza en el municipio de Navas del Rey, en un reducido área de 2x2,5 km en el que encuentran representación las distintas fases de la sucesión secundaria que se inicia con pastos, seguidos por matorral, arbustos y bosque...
The abandonment of cropland constitutes a process of land use change that can lead to the natural regeneration of soils and plant cover However, abandoned land has a variety of responses depending on the time elapsed since abandonment, the characteristics of the site, possible post-abandonment disturbances, previous and subsequent management, climatic conditions, etc., which condition plant succession and soil properties leading to ecosystems and landscapes as contrasted as forests, scrub, grassland and almost bare soils, which undergo changes at different time rates (Lasanta et al., 2021). In this context, the present doctoral thesis focuses on the evolution of soilproperties that have been altered as a result of the degradation associated with agricultural use (vineyard), and the progressive influence of plant recolonization and soil recovery over a more than 50-year period of abandonment. The study is carried out in the municipality of Navas del Rey, in a small area of 2x2.5 km in which are represented the different phases of the secondary succession that begins with pastures, followed by thicket, shrubs and forest...
