What’s in Your Fertilizer?

Whether you use organic or inorganic fertilizer, you may not know exactly what’s in it. The label will tell you the percentage of NPK, of course, but what else is in it? Trace elements, micronutrients, heavy metals? How can you find out?

I have come across a great website that has a database of hundreds of commercial fertilizers, both organic and inorganic. It is so extensive, I can’t imagine that any fertilizer you can buy in stores or online isn’t in their database! And the database is organized in alphabetical order based on the product’s official name. For example, Alaska Fish Emulsion (one of the fertilizers I use) is listed under A.

The database is maintained by the Washington State Department of Agriculture. The information is very easy to understand and is in chart format. Before buying your fertilizer, check it out.

And while you’re there, feel free to roam around their website. You can never learn too much about gardening!

  1. Your page looks great! You are a talented writer. On a lighter note – every time my 2 year old hears the word fertilizer he says 10-10-10.
