Corporacion Colombiana de Investigacion Agropecuaria, CORPOICA, Colombia

 

The Corporacion Colombiana de Investigacion Agropecuaria, CORPOICA is a mixed economy, non profit, private-law Corporation, created by the Colombian Government in 1993, under the Science and Technology law. It was designed to strengthen and to direct research and transfer of technology to the agricultural sector, with the commitment and participation of the private sector.

The Corporation is integrated by the country’s agricultural sector: guilds, universities, private enterprise, government bodies (national and local) and rural organizations. Corpoica´s basic mission is to generate scientific knowledge and technological products and services to improve the national agricultural production efficiency and contribute to the welfare of the Colombian population.

The Aims of CORPOICA are:

·         To develop and sustain excellent scientific and technological capabilities for strategic and applied research in crop, animal and related sciences

·         To improve the competitiveness of agricultural production in Colombia

·         To develop an equitable way of distributing the benefits of technology

·         To ensure that crop and livestock production systems are sustainable through the rational use of natural resources.

·         To develop biotechnology - based products and to facilitate their application to solving production problems in the tropical ecosystems.

CORPOICA is the national Institution responsible for strategic and applied research on agriculture. A broad multidisciplinary approach to strategic research and technology transfer was adopted. Strategic research programs include Genetic Resources and Biotechnology, Natural Resources and Environment, Integrated Pest Management, Ecophysiology and Animal Nutrition, Animal Health, and Production Systems.

Dr. Leyla Amparo Rojas is soil scientist and and Director of the Soil Laboratory. Her main research activities are the determination of the availability of nutrients for plants in order to establish sustainable fertilization programs and strategies to inhibit uptake of toxic elements and toxic substances. The research in the National Program of Biophysical is related to the study of the dynamics in the soil of elements not only as plant nutrients but also as toxic elements. During the last five years research has been focussed on plant nutrients such as potassium, sulphur, phosphorous, and toxic elements such as aluminium, selenium, molybdenum, cadmium and arsenic
