Typically not. Most are meant to slow dissolve and so will clog a sprayer if not fully dissolved. Stuff like Miracle Grow is obviously meant to be dispensed in water (they also have liquid fertilizers for sale). Plain uncoated Urea could be dissolved if given enough time or mild heat while mixing.

But if you are just trying to use up a bag of regular fertilizer by thinking you can mix it in some tap water and use it's not a great idea (I tried it a couple years ago and should have just disposed of it properly).
