CENTRO DE EDAFOLOGIA Y BIOLOGIA APLICADA DEL SEGURA CSIC The Spanish National Research Council (CSIC) is the largest public institution dedicated to research in Spain and the third largest in Europe, belonging to the Spanish Ministry of Science and Innovation through the Secretary of State for Research. CEBAS (Centro de Edafología y Biología Aplicada del Segura) is a CSIC´s institute located in Murcia (South East Spain), 50 Km from Mediterranean coast, under semiarid climatic conditions. Created in 1958, with the aim of promoting research in the fields of Agriculture Science, Natural Resource and Environmental Science. Actually, the CEBAS is arranged in five department: Nutrition and plant physiology / Plant breeding and phatology / Food science and technology / Soils and Water Conservation and Organic Refuse Management. CEBAS initiated its research activity in the middle 80, focusing its activity on studies on soil organic matter and humic fractions, as well as in the search of new sources of organic matter, which could replace the traditional organic amendments (peat, and manure) more and more scarce, their characterization, treatment, and their recycling in soil for both, agricultural purposes, and degraded soil rehabilitation. In the last 12 years it has carried out studies dealing with the use of microbial and biochemical marker in studies of soil quality, soil degradation and rehabilitation, in both natural and agricultural systems. The scientific production of the group from its beginnings has been qualitatively and quantitatively important (the principal investigator has published more than 130 SCI articles and several books and book chapters),being a group pioneer in the studies of organic waste stabilization (composting) and waste recycling, soil enzymology and bioindicators of soil quality, processes of soil degradation and desertification, as well as in the use of urban wastes as strategy for degraded soil rehabilitation.
