Interest in the impact of deforestation on climate in Amazon has been shown in several models and projects. Previous studies concentrated on the transformation from forest to pasture. However, in recent years, there has been an increase in the area of rice and soy bean plantation in the Amazon. In the Large scale Biosphere-Atmosphere experiment in Amazonia (LBA) there is a continuing effort to understand the effects of this consequence of deforestation by generating a nearly continuous flux data set. This study presents the results of turbulent flux measurements of carbon, heat, and moisture using the eddy correlation system over an agricultural site in the Eastern Amazon region. During the last 5 years this field has been transformed from a pasture to a rice and soy bean plantation. We will show the changes in turbulent fluxes (CO2, H20, and heat), radiative parameters (albedo and PAR-albedo) due to changing landscape from a pasture to crop fields. We also will show the impact of burning and plowing techniques on these parameters.
