| General Comments: | This article is one of eight articles (besides the overiew article) for Part II of a SWAT Special Issue that was published in Agricultural Water Management. The citation for the overview article is: Volk, M., D. Bosch, V. Nagia and Balaji Narasimhan. 2017. SWAT: Agricultural water and nonpoint source pollution management at a watershed scale—Part II. Agricultural Water Management. 180(Part B): 191-193. Doi: 10.1016/j.agwat.2016.09.029.
Note also that the "SWAT-K" model decribed in this paper represents new potassium algorithms and is a different SWAT-K model than the one previously developed for South Korean applications (see following example studies: (1) Kim N.-W., A.-H. Shin and C.-G. Kim. 2009. Comparison of SWAT-K and HSPF for hydrological components modeling in the Chungju Dam Watershed. Journal of Environmental Sciences. 18(6): 609-619. (2) Kim, N.W., I.-M.
