1. A composition for tracing the source of a high value crop selected from the group consisting of cannabis, ginseng, a gourmet mushroom, a gourmet garlic, and a rare herb comprising:
a first element selected from the group consisting of strontium (Sr), neodymium (Nd), calcium (Ca), magnesium (Mg), potassium (K), boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), and combinations thereof; and
a second element comprising nitrogen (N), phosphorus (P), and potassium (K) in an amount sufficient to support the growth of a high value crop selected from the group consisting of cannabis, ginseng, a gourmet mushroom, a gourmet garlic, and a rare herb; and
a third element comprising stable isotopes wherein stable isotopes of the third element are present in a mixture that provides an isotopic fingerprint for tracing the source of the high value crop into which the composition has been incorporated;
the mixture of stable isotopes is selected from the group consisting of 87Sr/86Sr, 87Sr/84Sr, 87Sr/88Sr, 143Nd/144Nd, 143Nd/142Nd, 143Nd/145Nd, 143Nd/146Nd, 143Nd/148Nd, 143Nd/150Nd, 42Ca/44Ca, 24Mg/26Mg, 25Mg/26Mg, 39K/41K, 11B/10B, 37Cl/35Cl, 65Cu/63Cu, 56Fe/57Fe, 56Fe/58Fe, 57Fe/58Fe, 55Mn/53Mn, 94Mo/95Mo, 94Mo/96Mo, 94Mo/97Mo, 95Mo/96Mo, 95Mo/97Mo, 96Mo/97Mo, 66Zn/67Zn, 66Zn/68Zn, 67Zn/68Zn, and combinations thereof;
wherein the composition is incorporated into the high value crop during the growth of the high value crop.
