A controlled release fertilizer has been prepared comprising a nutrient core coated with one or more moisture barrier coatings, at least one of said moisture barrier coatings comprising: at least one polyethylene wax; and a thermoset polyurethane from the reaction of a polyol and a polyisocyanate. The weight ratio of thermoset polyurethane to polyethylene wax is from about 50:50 to about 98:2. The polyethylene wax is heated above the melt point of the polyethylene wax and mixed and dispersed into the polyol component of the thermoset polyurethane in a ratio of 90-70% polyol to 10-30% polyethylene wax before the thermoset polyurethane-forming mixture is applied to the surface of the nutrient core and cured. A coating of a high temperature microcrystalline wax can be applied prior to final curing of the thermoset polyurethane to the coated nutrient core particles.

A money and card holding assembly includes a housing that has a bottom wall, a top wall and a peripheral wall. The peripheral wall has a peripheral break therein positioned generally equidistant from the top and bottom walls so that a top portion and a bottom portion of the housing are defined. A hinge hingedly couples the top portion to the bottom portion so that the top and bottom portions may selectively be positioned in an open position or a closed position. The hinge hingedly couples an upper portion of the back wall to a lower portion of the back wall. A first plate is attached to the lower portion of the back wall and is biased toward the bottom wall. A second plate is attached to upper portion of the back wall and is biased to the top wall.
