Agricultural potassium sulfate (LN K2SO4) was obtained from SDIC Xinjiang Lop Nur Potash Co. Ltd., China. Chemical grade polyethylene glycol 1000 (PEG 1000), sodium tripolyphosphate (STPP), and analytical grade reagents for gravimetric methods and Volhard method (sodium tetraphenylborate, ethylenediaminetetraacetic acid disodium salt, ammonium iron sulfate, BaCl2 and AgNO3) were purchased from Sinopharm Chemical Reagent Co. Ltd. Industrial grade urea phosphate (UP) was purchased from Tianjin Kemiou Chemical Reagent Co. Ltd. Tap water was used in all experiments and its physicochemical properties are shown in Table 1 . The concentration of metal ions (K+, Na+, Mg2+, Ca2+) was determined by an atomic absorption spectrophotometer (AAS, AA-6880 SHIMADZU, Japan). The concentration of SO42− and Cl− anions was determined by the barium chloride gravimetric method and the Volhard method, respectively.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
