I couldn't agree more Bob. I have been doing it for years and the combination of improved soil condition along with the commercial fertilizer has allowed me to grow plenty of veggies in a very small space here in the city.

As for the salt(s), it is like I said in another post--it is not the presence of salt(s) but the concentration (or everything here would be dead for miles inland due to salt spray when we have hurricanes).

BTW --just to make it clear, pretty much everything that plants take up are salts or ions--whether it is an ammonium ion, a nitrate ion, a potassium ion--it is part of a salt--they do not take up much in the way of non-ionic macro molecules although they do take up some.
