is amonia harmful to live oak trees



  1. 0 Votes

    Ammonia salts are used in certain fertilizers, but by no means is ammonia good for all plant life.  Ammonia is toxic and very caustic, and may cause problems, including defoliation, if an oak tree comes into contact with a sizeable quantity of it.

    In large concentrations, ammonia like any other substance can be and is toxic to other organisms. But in weaker concentrations, like one tablespoon per gallon of water, ammonia becomes a source for nitrogen, which is beneficial to all plants. Keep in mind though, large amounts of nitrogen can result in excessive weak growth in a plant, that in itself is not condusive to a plants long term health.
