Using a process model and regression kriging to improve predictions of nitrous oxide emissions from soil

Mapping continuous depth functions of soil carbon storage and available water capacity

“…This affected the final model predictions in that only a slight improvement was achieved when they were incorporated into predictions. Other studies such as Odeh et al (1995) and Stacey et al (2006) have reported greater success using the regression kriging approach we implemented for this study.…”

Soil Organic Carbon Density Spatial Distribution and Influencing Factors in a Karst Mountainous Basin

“…The value of C 0 indicated the degree of variation in the soil. The higher the value of C 0, the higher the degree of variation caused by the random part; on the contrary, the variation was mainly caused by structural influences [21][22]. If the value of C 0 was smaller than 25%, the variable had an intense spatial correlation, between 25% and 75%, and the variable exhibited medium spatial correlation; if the value was larger than 75%, the variable had weak correlation.…”

Indicator and probability kriging methods for delineating Cu, Fe, and Mn contamination in groundwater of Najafgarh Block, Delhi, India

“…The geostatistical concepts and its applications are reported by different researchers around the world (Isaaks and Srivastava 1989;Goovaerts 1997;Kumar and Ahmed 2003;Stacey et al 2006;Lu et al 2007;Lado et al 2008;Santra et al 2008;Liu et al 2009;Orton et al 2009). Specifically, indicator kriging (Goovaerts 1997), which is a nonparametric approach, is more advanced due to its ability to take the data uncertainty into account and often used to predict the conditional probability for the categorical data of an unsampled location (Goovaerts 1994;Oyedele et al 1996).…”
