I have recently been purchasing bags of rabbit pellets as an organic
fertilizer for both my lawn and plants. I have read a few minor
concerns over the salt content though. The bags I use say anywhere
from .3 to .6% salt. Is this high enough to make an issue of? It seems
to be quite low to me, but I'm hardly an expert on the subject.

I've been using alfalfa pellets mainly, rabbit pellets sometimes for
fertilizing. Excellent choice. My native soil is very sandy and these
provide OM, micronutrients, and slow-release nitrogen. I suggest you
buy rabbit pellets with a high percentage of alfalfa or 'forage greens'
vs. grains (which tend to be cheaper anyway). If you have access to
a feed store which stocks supples for horses, straight alfalfa pellets
would be cheaper yet.

Would repeated applications cause a salt buildup or are the levels
equal to naturally occurring salts? Is this a higher salt % than
chemical fertilizers? I would greatly appreciate any info on this, as
I don't want to keep doing it and find out too late that I screwed my
whole yard .

I doubt that it would be a problem unless you are growing in a very
difficult climate and soil area (where you are totally dependent on
irrigation water, for instance).

Chemical fertilizers may contain salts of various types (potassium salts,
fior instance).
