Soil organic carbon prediction with terrain derivatives using geostatistics and sequential Gaussian simulation
Original language description
This current study investigated the relationship between soil organic carbon SOC and terrain derivatives on soil developed on dissimilar lithology while comparing the best modelling approach. Sixty bulk soil samples were taken from the depth of 0 to 30 cm according to five identified basement complex materials and analyzed for SOC. The models considered are ordinary kriging OK, principal components kriging (PCA-OK) and regression kriging (RK). For the predictions accuracy, 2 fold, and leave one out cross validation was carried out. The study indicated SOC in soil developed on granite gneiss and biotite hornblende gneiss to be significantly higher than those on other lithology materials. RK improved the map structure with terrain derivatives, but the area was generally low in SOC. Model limitations showed that OK requires larger samples to improve the quality of prediction. Also, RK significant dissatisfaction is that the regression model parameters and covariance function parameters need to be estima
