I urinate on my pineapple plants regularly, in non phytotoxic amounts.

I was not able to find ammonia in the store, even after asking for it. I
saw bleach and other anti fungal bathroom measures, but no ammonia. This
may have something to do with the post Murray Federal Bldg era. Probably
not such a good idea any ways.

I've read warnings not to mix ammonia and vinegar.

Manure and alfalfa would have to be cut into the soil before planting. Or I
suppose you could make manure tea by putting it in hosiery and soaking in
water.
