Planting time organic fertilizer suggestions needed

First a little background...
My garden has slowly gone organic though I was never one to use much in the way of pesticides anyway. I just don't have an insect pest problem big enough to warrant treating. This may be becuase I don't grow things that are very pest susceptable for the most part. One thing i have had a problem with is flea beetles in egglplant and SVB in zucchini. I used rotenone for the eggplant and Bt for the zuchini last year (are they considered organic?) other than that I don't treat for anything. I do have some disease issues but planting resistant varieties has helped there.

I am going to be putting my tomatoes, peppers, squash and beans in the ground soon and am looking for organic suggestions. In the past I would mix a handfull of 10-10-10 and a bit of epsom salts in the soil I would remove from the planting hole. I do not have access to compost (already used mine up for some other plantings) or manure (not truck to haul it in and nobody willing to do the hauling). I have a worm farm but I've already harvest and pretty much used that up. I have made alfalfa tea and have a jug of fish emulsion. Can I use either or both of those at planting, will they burn the plants and do they give enough P and K to balance the N? The last thing I want to do is overload my tomatoes and peppers with nitrogen to get lots of leaves but no fruit.

I always throw a half a trowel of bat guano in every transplant hole--for everything. Works great for me, never burns a thing, you can buy it where ever they sell a lot of organic products in 1 lb. buckets. Actually my philosophy of gardening down here in Texas (and the answer to all life's problems in my opinion..lol) can be solved by more bat guano and more mulch.
