Abstract
Geosoil permite almacenar, consultar e interpretar información tanto del suelo como de su entorno biofísico a diferentes escalas: parcela, finca, comunidad, municipio, departamento, región, país. Opera a partir de una base de datos relacional elaborada en ACCES 2000, compuesta por una serie de tablas principales estructuradas con información a diferentes niveles jerárquicos que permiten la caracterización de las propiedades del suelo. Los elementos morfológicos y analíticos del suelo se combinan para conformar indicadores de calidad mediante un sistema de calificación que permite visualizar el grado y el número de limitaciones que podría tener un suelo para ser utilizado en agricultura. Además, posee módulos en los cuales el usuario puede: (a) adicionar o consultar características espaciales y de atributos del suelo; (b) visualizar la interpretación de los indicadores de calidad, agrupados en rangos de limitación (c) determinar la aptitud general del suelo para un cultivo específico mediante la comparación entre oferta (suelo) vs. demanda (requerimientos del cultivo); (d) calcular necesidades de fertilización; (e) generar reportes de la variabilidad en profundidad de algunas características, para uno o más suelos; (f) cartografiar los resultados mediante un link con el SIG MapMaker y (g) visualizar mapas de variabilidad espacial y/o temporal (isolíneas) de la variable utilizada como indicador. ABSTRACT The System Georeferenced of soil quality indicators for the savannas of Colombia. Geosoil allows to as much store, to consult and to process data of the soil as of his biophysics surroundings on different scales: parcel, property, community, municipality, department, region, and country. It operates from a relational database elaborated in ACCES 2000, composed by a series of structured main tables with information at different hierarchic levels that they allow the characterization of the properties of the soil. The morphologic and analytical elements of the ground are combined to conform indicators of quality by means of a qualification system that allows visualizing the degree and the number of limitations that could have a soil to be used in agriculture. In addition, it has modules in which the user can: (a) to add or to consult space characteristics and of attributes of the soil; (b) to visualize the interpretation of the quality indicators, grouped in limitation ranks; (c) to determine the general aptitude of the soil for a specific culture by means of the comparison between supply (soil) versus demands (requirements of the culture); (d) to calculate the fertilization necessities (e) to generate reports of the variability in depth of some characteristics, for one or more soil; (f) to map the results by means of a link with the MapMaker GIS (g) to visualize maps of space and/or temporary variability (isolines) of the variable used like indicator. Key words: indicators, soil quality, Geographical Information Systems, soil database, land degradation and land evaluation, savannas.
