Is it possible for the soil pH to be around 8, but with negligible amounts of carbonates, bicarbonates and exchangeable sodium?

Can this pH of 8 be due to the presence of other substances? Or do I have an error somewhere in the analysis? Thank you!

Ali i have read this paper but i cant understand. how they make the same the spatial resolution. if you understand please tell me

Chong Wei

Maybe you have not necessarily made the same spatial resolution for the SWAT model and soil moisture data. The soil moisture output in SWAT is on the subwatershed and HRU scale, it is possible to calibrate the SWAT model on the subwatershed scale. To calculate the average value of soil moisture of a subwatershed and use this data to calibrate the relevant parameters in SWAT, maybe it is an alternative method.
