Single Party Framework for Fertilizer, Seeds, Supplies, Sand, Rootzone & Stone for University of Limerick UL0802

Description

Supply of fertilizer, seeds, chemicals, fungicides, line marking paint, landscaping & grounds tools, sand, rootzone and stone. Items have been split into 2 lots. Lot 1: Supply of Fertilizer, seeds, landscaping supplies Supply of all products needed for Nutrition programme for sports pitches based on soil sampling Lot 2: Supply of Sand, Rootzone and Stone Topdressing Sand: Topdressing sand should have a minimum of 50 percent of its particles in the medium-sized fraction (0.25-0.50 millimetres (mm) in diameter) and 15 to 40 percent in the coarse fraction (0.5-1.0 mm in diameter). The fine sand fraction (0.15-0.25 mm) should not exceed 25 percent, and the very fine fraction (0.05 - 0.15 mm) should not exceed 5 percent. Ideally, the material should have no particles greater than 1.0 mm in diameter given the difficulty in getting these larger particles to work down into the turf canopy.
