Alaska Pure Kelp Plant Food is a fertilizer marketed by Lilly Miller Brands. The NPK analysis for the fertilizer is 0.13% nitrogen (N), 0% phosphorus (P2O5), and 0.6% potassium (K2O). Heavy metal analyses of the product reported to Oregon and Washington State can be found in the info box on this page. These analyses show the quantities of heavy metals, in parts per million (ppm), of arsenic (As), cadmium (Cd), cobalt (Co), mercury (Hg), molybdenum (Mo), nickel (Ni), lead (Pb), selenium (Se) and zinc (Zn) present in a sample of the product. Oregon does not report levels of cobalt, molybdenum, selenium or zinc.

The fertilizer heavy metals analyses information for Alaska Pure Kelp Plant Food is from the Oregon Department of Agriculture and the Washington State Department of Agriculture. The information on WikiFootprints was last obtained from the agency websites on 4 May 2017. WikiFootprints is not an official source of this information and may not represent the most recent analysis of the product. Official data can be obtained from the Oregon Department of Agriculture Fertilizer Program and the Washington State Department of Agriculture Fertilizer Product Database.[1][2]



Usage

Fertilizers and similar products can contain significant quantities of heavy metals, such as arsenic, cadmium, lead, mercury, and nickel. Fertilizers are often reapplied at regular intervals, so there can be a cumulative effect on the soil. A few departments of agriculture monitor the concentrations of heavy metals, in agricultural products, to protect human health and natural resources from toxicity.

The Oregon Department of Agriculture sets required lower limits of detection for each heavy metal concentration measured. At the minimum laboratories must be able to detect concentrations of 10.0 ppm arsenic, 5.0 ppm cadmium, 5.0 ppm lead, 0.20 ppm mercury, and 5.0 ppm nickel.[3] The concentrations of arsenic, cadmium, lead, mercury and nickel, reported to Oregon, are at or below the maximum lower limit of detection.[1]
