Whoops, I forgot our eco-nazi friends over at Rutgars University. http://njaes.rutgers.edu/pubs/soilprofile/sp-v16.pdf While the great majority of commercial fertilizer products are generally regarded as safe and free of harmful levels of heavy metal contamination a limited number of products of concern have been identified in the garden center and fertilizer dealer market place. An example of a product of concern that is widely available in the home garden fertilizer market is Ironite. A recent study found that Ironite contains up to 3600 mg/kg As and 2900 mg/kg Pb and that solubility testing indicates that the product should be classified as a hazardous waste. On August 15, 2005, the New Jersey Department of Agriculture issued a ³stop sale² on Ironite 100, but other Ironite products remain on the market. A limited survey of commercial products obtained from fertilizer dealers in New Jersey, conducted by Rutgers Cooperative Research and Extension, identified one zinc product of concern that contained 83 mg/kg Cd (Table 2). Also analysis of a commercial liming material found a Ni concentration of 194 mg/kg. New Jersey state officials, garden centers and fertilizer dealers are being informed about these suspect products. In New Jersey, commercial fertilizer products are regulated for guaranteed nutrient concentration by the New Jersey Department of Agriculture (NJDA). Although concentrations of nonnutrient substances in fertilizers and liming materials are not currently regulated, the NJDA will, on request from the public, test product samples for some heavy metals of concern. When a farmer, gardener, or fertilizer dealer has concerns about the guaranteed nutrient concentration in a fertilizer, quality of a liming material, or possible contamination of a product with heavy metals, the product in question may be sampled and tested by the NJDA, P.O. Box 330, Trenton, NJ 08625. Phone: 6099842222. -- Billy Bush and Pelosi Behind Bars http://www.youtube.com/watch?v=9KVTf...ef=patrick.net http://www.haaretz.com/hasen/spages/1009916.html |
