El Effect of different topographical attributes on organic carbon in several land uses
Abstract
The aim of this study was: to quantify the amount of soil organic carbon (SOC) stored at three depths and to relate various topographical attributes to the density of SOC at the site El Progreso, El Oro-Ecuador province. The study was conducted in four land uses: banana, young cocoa, mature cocoa and old cocoa, with SOC values between zero and 0,10 m of 25,6 g kg, 35,8 g kg, 13,2 g kg and 10,5 g kg respectively, and the predominant textural classes are: loamy clay (0-0.10 cm) and clay loam (0,30-0,40 cm). In each soil 1 ha was delimited to take soil samples at: four depths every 10 cm. The topographic attributes: drained area (AS), sediment transport factor (LS) and soil moisture (WTI), were taken from a digital elevation model (DEM) with a resolution of 12x12m. The SOC ranges decreased from the middle part of the area under study (banana 38,4-8,1 Mg ha-1 ; young cocoa 36,20-10,50 Mg ha-1 ; old cocoa 13,80-0,94 Mg ha-1 ) with higher slope (10-20 %) towards the lower part (mature cocoa 18,80-08,40 Mg ha-1 ). Young cocoa land use showed the highest value of AS (10 286, 5) and in LS (11,44). Significant differences were also determined with the LS factor by crop and correlated with the total SOC. Therefore, LS (runoff) is the topographic attribute that most influenced the storage of SOC.Downloads
