Spatial distribution of the CO2 stream in archaeological dark earth area under cocoa and coffee cultivation in the municipality of Apuí, AM, Brazil
The Archaeological Dark Earth (ADE) are soils that can hold up to six times more organic carbon than surrounding soils without anthropic horizons, thus assuming higher CO2 emissions from these soils. The objective of this study was to investigate the spatial distribution of CO2 efflux, temperature a...

| description | The Archaeological Dark Earth (ADE) are soils that can hold up to six times more organic carbon than surrounding soils without anthropic horizons, thus assuming higher CO2 emissions from these soils. The objective of this study was to investigate the spatial distribution of CO2 efflux, temperature and soil moisture in an Archaeological Dark Earth area under cocoa and coffee cultivation in the municipality of Apuí, AM, Brazil. Sample grids of 42 x 80 m were set up, with space between points of 8 x 6 x 10 m and 10 m, respectively, for the cocoa and coffee areas. After data of CO2 efflux, temperature and humidity of the soil were collected, descriptive statistics and geostatistics analyses were done. The results showed that the evaluated parameters exhibited spatial dependence reaching a range of 25 to 40 m for CO2 stream ADE area with cocoa. The CO2 efflux in the cocoa area was higher, with an average value of 5.49 µmol m-2 s-1, compared to 3.99 µmol m-2 s-1 in the area of coffee CO2. |
