Just list vegetables. If you need to be specific, tomatoes. I just received a report on 2 samples and on one I listed two crops for the field, the other my vegetable garden. Be sure and send off a representative sample of your final mix. TX A&M soil/water test lab charges only $15 and you get your NPK and other macros (Ca, S, and Mg), micros, conductivity, pH, as well as recommendations of what to add. Save on postage, and send off a water sample for analysis too. You can use a 12 oz bottle.
Based on one soil sample, I put out a 150 lbs. of a 18-11-5 with Zn and Fe yesterday, and now we have a nice slow rain going on.
BTW, I bought 250 lbs. of high grade fertilizer
for $52 total from a feed store. Called up the manufacturing plant's agronomist (yes, a legitimate doctorate) and talked with him about a few issues, and went about my business. The N sources of this food are ammoniacal, just what I want to get a little pH reduction with very little leaching. IOW, you can get very good professional advice and cheap but high quality products if you do your homework. Stick with the professionals in the horticultural industry.

I'm not the be-all of gardening, I have alot to learn but when you understand that alot of salts are broken down into their respective ions BEFORE being taken within plant tissue, you must question such forum paradigms.
Thank you!
