Sistemas computacionais aplicados na avaliação técnica de agroecossistemas

Abstract

The purpose of this literature review was to describe three software applied in the technical evaluation of agricultural systems and their use. It is known that the agroecosystem performance depends on physical, chemical and biological components, hence, computer modeling can help increase efficiency in the use of available resources, directly affecting sustainability. Thus, the description gathered the Integrated Farm System Model (IFSM); Denitrification and decomposition (DNDC) and Environmental Policy Integrated Climate Model (EPIC); these three models can be applied in any situation to represent the behavior and / or the system performance, so they are in constant validation to suit the different methods, technologies or strategies used and are also efficient for field research, technology transfers and guidance to decision making about strategies in agro-ecosystems.
