NITROLIZED FIR FINES
Nitrolized Fir Fines are derived from construction grade Douglas fir building remnants. The fir fines are "nitrolized" to prevent nitrogen drag (the removal of plant-needed nitrogen by the wood.) The particle size of this material is 3/8 inch. Nitrolized Fir Fines improve soil structure, increase nutrient holding capacity of sandy soils, and improve water drainage. Nitrolized Fir Fines are a stand-alone amendment but can also be used as a component in container mixes or soil-less potting mixes. Available at all three locations.
