Agroecological Transition

La agricultura industrial en gran escala promueve una explotación intensiva del suelo que puede comprometer su sostenibilidad en el tiempo. Como respuesta, la Agroecología propone una serie de prácticas que devuelven al suelo su capacidad productiva. Esta investigación empleó un marco de análisis sobre sostenibilidad, para identificar indicadores que relacionen el estado y manejo del suelo con las dimensiones física, química y biológica. Fueron seleccionados nueve indicadores de sostenibilidad aplicados en veintitrés fincas con distintas trayectorias en el proceso de transición agroecológica localizadas en Subachoque, Cundinamarca, Colombia. Los sistemas productivos con cinco o más años en transición obtuvieron los valores máximos para ocho de los indicadores evaluados. Se evidencia cómo la agroecología genera cambios en la sostenibilidad del manejo del suelo, asegurando características edáficas apropiadas para mantener su capacidad productiva a través del tiempo

Variable Charge Soils

This book, based on research carried out at the Academia Sinica over the past 30 years, explains the basic difference between the variable charge soils of tropical and subtropical regions, and the constant charge soils of temperate regions. It will focus on the chemical properties of the variable charge soils--properties which have important bearing on soil management practices, including maximizing soil productivity and combating soil pollution.

Edaphic arthropod communities provide valuable information about the prevailing status of soil quality to improve the functionality and long-term sustainability of soil management. The study aimed at evaluating the effect of plant and grass cover on the functional biodiversity and soil characteristics in a mature olive orchard (Olea europaea L.) managed for ten years by two conservation soil managements: natural grass cover (NC) and conservation tillage (CT). The trees under CT grew and yielded more than those under NC during the period of increasing yields (years 4–7) but not when they reached full production. Soil management did not affect the tree root density. Collecting samples underneath the canopy (UC) and in the inter-row space (IR), the edaphic environment was characterized by soil structure, hydrological properties, the concentration and storage of soil organic carbon pools and the distribution of microarthropod communities. The soil organic carbon pools (total and humified) were negatively affected by minimum tillage in IR, but not UC, without a loss in fruit and oil yield. The assemblages of microarthropods benefited, firstly, from the grass cover, secondly, from the canopy effect, and thirdly, from a soil structure ensuring a high air capacity and water storage. Feeding functional groups—hemiedaphic macrosaprophages, polyphages and predators—resulted in selecting the ecotonal microenvironment between the surface and edaphic habitat.
