| Coffee (Coffee arabica L.) management in Costa Rica is changing from plantations associated with shade trees to monocultures; both of which receive large additions of N through fertilization. Understanding patterns and processes of N cycling within coffee agro-ecosystems could lead to the development of management practices that maintain productivity while minimizing environmental damage. My study investigated the N dynamics in paired shaded and unshaded coffee plantations in the Central Valley, all fertilized with about 300 kg N ha... |
