The researchers studied soil salinity in the Yellow River Delta using statistics and geo-statistics. They found that soil salinity varies across different depths and is influenced by factors like topography and climate. By using the CoKriging method, they were able to estimate deep soil salinity more accurately, reducing the estimated variance by 167.36% compared to traditional methods.
