Abstract
A method of making a vegetation-friendly ice melting composition with sub-zero ice melting characteristics is described. The method of making the composition includes mixing from about 60-90 parts by weight non-fully hydrated ice melter, which is preferably calcium chloride with from about 10-40 parts by weight of fertilizer, which is preferably urea. The most preferred composition is about 70 parts by weight of calcium chloride and about 30 parts by weight urea. The calcium chloride and urea are preferably admixed first to coat the calcium chloride. To this mixture is added a measured amount of powdered non-fully hydrated calcium chloride as a solid coatant. The non-fully hydrated calcium chloride by hydration forms a coating around the ice melt base. The resultant mixture is discharged from the mixer, screened and packaged.
