I would like to start canning my own tomatoes in both whole form and in
salsa. What is the best variety for this? I'd like to get something
that grows well in my sandy loam kansas soil and has a decent yield.

Also, we'd like to have a few slicer tomatoes for salads and to eat
plain, what makes a good tomato variety for this?

the past few years, we've only used miracle grow fertilizer about 3-4
times during the season without any ammendments to the soil. Should
we consider manure or other fertilizers to increase the tomato yield
out of our smaller garden?
