Desarrollo de modelos agroforestales para evaluación de tierras en Nicaragua
Five models corresponding to 5 types of land use, within basic agroforestry use in Nicaragua during 1992 were built using ALES. These models include: 1) high technology monoculture coffee plantation; 2) semi-technified monoculture coffee plantation; 3) coffee plantation with traditional tree shade; 4) coffee plantation semi-technified with tree shade and 5) forest plantation. Each model has a knowledge base and the area studied a database. In each model the physical and economic suitability were evaluated by classes (suitable and unsuitable), expressing the economic suitability by gross marginal income ( /ha/year), and net present value ( /ha). Results showed that availability of phosphorus was the most limiting factor in the physical suitability. Also the land use for coffee plantation in the traditional and semi-technified system had the best profitability. The forest plantation type showed less profitability, however, it 66 por ciento of this was classified in the category of physical suitability.
