Fertilizer Product Name Database
This database contains nutrient guarantees and laboratory reports on nine heavy metals for fertilizer products currently registered in Washington State. The Washington Standards for Metals are based on the Reported Metals and the maximum application rate of the product. To accurately compare products, the use rates need to be considered.
Definitions
The "Guaranteed Analysis" is the minimum percentage (%) of each nutrient as claimed by the company. Blanks and "0's" indicate no guarantee for that nutrient.
The "Reported Metals" is the maximum claimed concentration of each listed heavy metal based on the results of the lab analysis required by WSDA of a representative sample. The results are reported in parts per million (ppm).
