Are there any rapid analysis methods for compound fertilizers (N.P.K)?

As the title suggests, I would appreciate it if fellow users could recommend whether it is the automatic analyzer determination method in the data sharing area (GB/T22923-2008)
The time required according to the national standard methods is inevitable; I’ve looked into rapid methods before, but I haven’t seen any company using them!
Fast, how fast do you need it? With advanced instruments, nitrogen can be determined quickly; for P and K, if the gravimetric method is used, the results are available in 5-6 hours as well. No matter how fast you are, you can only do the part at the beginning; you just check whether it exists or not, without looking at how much it contains. It depends on your purpose!
That instrument is too expensive; it was developed at the expense of the manufacturers who produce such instruments, and it doesn’t have much practical value. If you have money, you can also play standard.
Some chemical companies have rapid analysis methods! . . . It has independent intellectual property rights! :）
