I agree. I use drip tape. I have a fertilizer injector, but have only put very soluble ferts in it. I have considered building a pipe and dripper system so that I can have easier access to the emitters to see if they are clogging up. That would let me run organic ferts through the injector, a lot of which tend to be goopy and cause clogs. If I clog up my drip tape under black plastic, I'm not going to realize it until the plants start to wither.
