Sistemas agroforestales de café (Coffea arabica) con laurel (Cordia alliodora) y café con poró (Erythrina poeppigiana) en Turrialba, Costa Rica. III. Modelos de la materia orgánica y los elementos nutritivos
Models for organic matter and nutrients (N, P, K, Ca and Mg) were prepared for the agroforestry systems of coffee (Coffea arabica) with laurel (Cordia alliodora) and poro gigante (Erythrina poeppigiana) based on studies carried out CATIE (Centro Agronómico Tropical de Investigación y Enseñanza) in Turrialba, Costa Rica. For each system an inventory was made for organic matter and nutrients considering as compartiments the plants (wood, branches, leaves, roots and fruits at age 4.5 years, 1982), the litter layer and the mineral soil (0-45 cm). The experiment began in 1977. As input into the system were measured anually (5 experimental year) growth, fertilization and nutrients in the rainfall. As output of the system are considered harvest (5 years) and lixiviation. As transfer processes were measured the litter production (naturally and pruning) and its decomposition. The models are presented grafically and discussed
