Why do all tomato feeds seem to be liquid? Sulphate of potash comes in a
solid form, so what is it that we can't mix with water ourselves?

Water is cheap, so the profit margin is high. I tried looking for
a low-nitrogen fertiliser in solid form, and came up with a
complete blank. Yes, I could make one up, but getting hold of
the minor nutrients would be a real pain :-(
