General description El programa de esta asignatura sintetiza el cuerpo de doctrina que actualmente constituye las Ciencias del Suelo, centrándose en el estudio de las propiedades, la organización y las funciones de los suelos. El núcleo del programa teórico, está estructurado en torno al estudio de los componentes minerales y orgánicos del suelo, las propiedades físicas, químicas y biológicas, así como la relevancia ecológica de las funciones que se derivan de estas propiedades. El programa teórico concluye considerando que los suelos son entes naturales que deben de ser protegidos en la misma medida en que los son las especies animales y vegetales.
Las prácticas pretenden no solo fomentar el aprendizaje de las técnicas generales de análisis de suelos en estudios genéticos y sistemáticos, sino contribuir al conocimiento de técnicas de estudio del suelo más específicas, desde el punto de vista físico, químico y biológico.

The scientific study of the soil is important for Biologists, mainly from an ecological perspective. Soil is essential in environmental studies and soil science contributes to understand important processes such as biogeochemical cycles, the structure ecosystems and factors from which primary production depends.

The course of Soil Science is designed to provide an overview of the fundamental: Physical processes, Chemical processes, Fertility, Biology, and Land Use. Both theoretical and practical contents in Soil Science should contribute to enhance the skills of Biology students at the UDC in the use of several instrumental techniques. A2

Soils act as substrates for vegetal communities and also as adsorbent and absorbent for nutritive, and allow life of many animal and vegetal organisms. Therefore our program pays particular attention to the “edaphosphere” as a complex dynamic and organised site, located in the interface between biosphere, lithosphere, hydrosphere and atmosphere. Soil is also the support of man-made spaces or sites influenced by man activity, such as urban-industrial areas and transport infrastructures. A6

Because of the role of the soil for terrestrial ecosystems, Edaphology has a particular interest in Environmental Biology. The soil food chain describes a complex living system and how it interacts with the environment, plants, and animals. The nature of soil makes direct observation of food webs difficult. Soil microbial communities are characterized in many different ways. The activity of microbes can be measured by their respiration and carbon dioxide release. The cellular components of microbes can be extracted from soil and genetically profiled, or microbial biomass can be calculated by weighing the soil before and after fumigation. A21
