Alaska Morbloom is a PK fertilizer from Lilly Miller Brands. The fertilizer contains 0% nitrogen (N), 10% phosphorus (P2O5), and 10% 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), lead (Pb), mercury (Hg), molybdenum (Mo), nickel (Ni), selenium (Se) and zinc (Zn) present in a sample of the product. Oregon does not report concentrations of cobalt, molybdenum, selenium or zinc.
The fertilizer heavy metals analyses information for Alaska Morbloom 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.
Fertilizers and other products used to increase soil fertility can contain notable amounts of heavy metals, such as arsenic, cadmium, lead, mercury, and nickel. PK fertilizers are often used on a regular basis, so there can be a cumulative effect on heavy metal concentrations in the soil. A few government organizations regulate 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. The concentrations of arsenic, cadmium, lead, mercury and nickel, reported to Oregon, are at or below the maximum lower limit of detection.
