I've been doing a lot of studying lately. When urea is used as a source of nitrogen aren't we just slowly killing the soil? Does the salt kill the bacteria/microbes in the soil? When I'm selling customers on my organic prgram I tell them it does. I use the example of spilling ice melt on your lawn and how it kills it. Is this information correct? Thanks for your input.

fertilizers all have a salt index! Some are higher than others, so you have to be carefull at the rate you apply fertilizers, for each application, and the total per year. I've seen the salt index on milorganite, extremely low, but so is uf, which is a sythetic fertilizer!
