Ah AM! This is where you've been hiding.
Salt = the leftovers from an Acid chemical and a Base chemical (non-acid) mixing. There are many different kinds of salt. The most common are the basic building blocks of nature, potassium, nitrogen (special class of vapor salt), and all the other minerals you feed your plants. All life needs salt or we would dry up very quickly and die, just like plants do without water.
Organic = delivered the same way nature does.
Non-Organic = Made in a factory with byproduct waste.
Both are the exact same salts. The only difference is where they came from.
In soil, the minerals are broken down into salt by enzymes.
Enzyme = a tiny chemical machine that breaks stuff down into its basic parts.
