Introduction
I'm agronomist, soil scientist and micromorphologist. My general interests are the application of soil micromorphology to soil genesis and to soil management practices, mainly in semi-arid mediterranean areas. Additionally, I like studying the relationships between soil structure and porosity and soil carbon.

Article
Full-text available
Soil organic matter (OM) is a source of fertility for food provisioning and a means for climate mitigation. A high pedodiversity observed over very short distances due to both past and present land use, such as in Western Africa (Northern Togo), makes this a crucial issue. In particular, some small spots covered by sacred forests (forêts sacrées) o...
Article
Full-text available
The increasing regression of Urmia Lake in the last 30 years has brought about the salinization and sodification of arid soils from the shoreline, which has aggravated land degradation in this area. The objective of this work was to assess the changes in the soils brought about by progressive and fast salinization of the region, and to determine th...

The Pyrenean range (NE Iberian Peninsula) has some favourable lithological and climatic conditions (iron-rich parent materials and udic moisture regimes) for the formation of acid sulfate soils (ASS) that have not been reported on from the region until now. The analyses of a drained peat bog near València d'Àneu revealed a pH (1:2.5) of 3.7. We hyp...
Chapter
Carbonate-rich soils are common in many arid and semiarid areas. Many of them are cultivated, and agriculture is expanding by the spreading of irrigation. Although the soil mineral fraction has been usually considered little or not affected by agricultural management in the short term, increasing evidence suggests that this is not the case for carb...
Article
Agricultural terraces are the most widespread archaeological landforms worldwide. Despite their far-reaching prevalence in many inhabited parts of the world, archaeological soils in terraces (hereafter ‘terrace soils’) are scarcely studied and their nature is poorly defined. This study aims to depict a space–time framework for the development of ca...
Article
Full-text available
Gypsum is widely found in soils under arid and semi-arid climates due to its semi-soluble nature. In spite of that, they are less known than other soils, and this has generated some misunderstandings in some initial pedological concepts and in soil classification systems. In addition, the quantification of gypsum, and in particular of its secondary...

Soil micromorphology is the technique in soil science that enables us to observe how soil constituents are organized at a microscopic scale, i.e., between field and submicroscopic observations. Special terms are used to study and describe soil microfabrics viewed in soil thin sections, which have evolved from a genetic to a more morphoanalytical ap...
Article
Most of the loess in the southeast of the Ebro Valley encompass mostly the Marine Isotope Stage 2 (MIS2) but some exceptions date back to more than 115 ka. Soils formed on these older loess deposits are normally categorised as red soils. We studied the pedogenesis of two of these red soils. Macro-micromorphological, particle size, color-redness rat...
