Fertilizer composition including animal manure and cement kiln dust
A composition for use as fertilizer includes cement kiln dust and animal manure. The content of cement kiln dust and animal manure in the composition is selected as a function of either weight or volume. The content of cement kiln dust is greater than or equal to the content of animal manure. The fertilizer composition is formed by mixing the cement kiln dust and animal manure at ambient temperature and pressure.
A flute filler for a standing seam metal roof having a plurality of ribs and having valleys therebetween comprising is provided. The flute filler comprises a sheet having a plurality of planks secured thereto. The planks are arranged to be side by side at spaced intervals such that each plank is adapted to be disposed in a valley and the sheet overlies the planks when the flute filler is situated on the roof. A cover board and a roofing membrane may be disposed over the sheet of the flute filler. In order to situate the flute filler on the roof, the planks are placed in a valley of the standing seam roof which can be accomplished by unrolling a rolled flute filler.
