Sažetak: | The goal of this research was a thorough assessment of the biophysical and radiometric characteristics of the cultivated pastures in the Cerrado biome, based on both field and remote sensing data acquired in August 2009 and February 2010. The study area, located in the State of Goiás, Central Brazil, comprises an area of approximately 77.806 km², between latitudes 14º 00 S and 16º 30 S, and longitudes 48º 30 and 51º 10 W. Based on our data and results, we found a substantial difference between the two periods investigated, particularly concerning the green biomass and % green cover. While the total biomass remains mostly unchanged, the green biomass varies from 1.2 to 3.1 t/ha between August and February. Likewise, the % green cover increases as much as 65%. All these data and results, situated within the context of a larger initiative, certainly may be instrumental in promoting a more effective and sustainable pasture management in the Cerrado biome. |
