Secuestro de carbono y mejora de la calidad del suelo bajo laboreo de conservación en condiciones mediterráneas (SO de Andalucía)

Abstract

[ES]: El presente trabajo de Tesis se ha desarrollado para evaluar cómo la implementación de la agricultura de conservación puede mejorar la calidad del suelo en diferentes escenarios. El principal objetivo del estudio pretende conocer cuáles de los parámetros analizados pueden ser utilizados como índices fiables de calidad del suelo tanto en parcelas experimentales como en fincas comerciales, bajo condiciones Mediterráneas. Para ello se analizaron parámetros químicos y bioquímicos en diferentes muestras de suelo, tanto en suelo masivo, a diferentes profundidades, como en fracciones de agregados de suelo por tamaño y densidad y muestras de ácidos húmicos y fúlvicos. Además, se obtuvo una caracterización más precisa de la materia orgánica (MO) del suelo mediante técnicas de alta resolución de espectrometría de resonancia magnética nuclear de 13C de estado sólido y espectrometría de masas de resonancia iónica en ciclotrón con transformada de Fourier. El grueso del estudio lo constituyen cinco publicaciones científicas que abordan diferentes aspectos derivados de la aplicación del laboreo de conservación tanto en parcelas experimentales como en fincas comerciales de Andalucía Occidental.

[EN]: The present Thesis work has been carried out in order to evaluate how the application of conservation agriculture could provide benefits to soil quality in different scenarios. The aim of this work was to establish how the parameters analyzed could be used as indexes of soil quality and which of these are the most appropriate and viable for experimental and commercial farms under Mediterranean conditions. To reach this objective, chemical and biochemical parameters were analyzed on different types of soil samples, such as bulk soil at different depths, aggregate fractionated soil, density fractionated soil, and chemically extracted humic and fulvic samples. Furthermore, a deeper characterization of soil organic matter was obtained by new techniques of solid state 13C nuclear magnetic resonance spectrometry and Fourier transform ion cyclotron resonance mass spectrometry. The central body of this manuscript consists of five peer-reviewed publications that investigate different aspects of the application of conservation tillages in farms situated in Andalucía, SW of Spain.
