“…Which method is the priority selection still needs further discussion in the hilly red soil region. Although some studies have been reported in other regions [15,27], the results may not be suitable for the red soil region due to the complex terrain and fast changing soil types and land-use patterns. A comprehensive comparative study for different interpolation methods in this area is still necessary and has important practical significance.…”

“…For the polygon-based method, soil property data can be linked to soil type, land-use pattern, climate zone, agricultural region, and even administrative region unit and regular grid [19,[23][24][25]. Meanwhile, kriging has also evolved into the methods such as universal kriging (UK), co-kriging (CK), regression kriging (RK), and kriging combined with other auxiliary information (soil, land-use, vegetation type, and other related information) [26][27][28][29]. After being modified, the polygon-based and kriging methods are usually much more adaptive in the spatial prediction of SOC in some soil regions.…”

“…The E-BLUP is, in effect, a combination of a regression-type prediction from the covariation and a kriging-type prediction from the random effect. This was discussed in the context of soil information by Lark et al (2006), and the approach has been applied in various studies (e.g., Chai et al, 2008). In addition to the predictor, a prediction error variance is also computed which provides a measure of the uncertainty of the prediction.…”
