[ES] Después de analizar la tendencia actual al aumento de la superficie cultivada con siembra directa o no laboreo y al descenso de la superficie total de barbecho y la del barbecho mantenido con laboreo tradicional, se presenta una síntesis de los resultados obtenidos en las últimas dos décadas sobre los beneficios derivados de la reducción del laboreo, a través de la adopción de técnicas de agricultura de conservación (laboreo reducido y no laboreo) y su influencia en algunos parámetros edáficos, agronómicos y medioambientales en los sistemas de cultivo de secano semiárido del Valle del Ebro. La conclusión es evidente. El uso de dichas técnicas, especialmente el no laboreo, como alternativa al laboreo intensivo tradicional, es una estrategia recomendable para mejorar tanto la calidad y productividad del suelo como la conservación y sostenibilidad de dichos agrosistemas.
[EN] In the context of the current nationwide trend towards the increase in the proportion of cultivated land with no tillage and the decrease of total fallowed land area including that of traditional tilled fallow, the authors overview selected results obtained during the last two decades on the beneficial influence of conservation agriculture practices (reduced tillage and no-tillage) in soil, agronomic and environmental parameters in semiarid dryland farming systems of the River Ebro Valley. In the light of the results presented, it becomes evident that adopting conservation tillage technologies, especially no-tillage, is a viable alternative to conventional tillage for improving not only soil quality and productivity but also the conservation and sustainability of those agricultural systems.
