Nitrolized Redwood Shavings are shavings derived from the surfacing of lumber at sawmills treated with an ammonium nitrate fertilizer to prevent the nitrogen draw from the soil created by microorganism’s use of nitrogen to decompose the woody material . The shavings are approximately 3/4” with some sawdust. Nitrolized Redwood Shavings decompose at a slower rate than shavings derived from soft woods such as Fir or Pine. When incorporated into soil, Nitrolized Redwood Shavings improve soil structure, tilth, increases nutrient holding capacity of sandy soils, and improves water drainage.


Nitrolized Redwood Shavings Cutsheet


  • Amending native sandy soils
  • Component of container mixes and soil-less potting mixes
  • Mulch


  • Amending soil, excavate hole twice the diameter of the root ball and amend excavated soil with Nitrolized Redwood Shavings and backfill with mixture. To prepare soil for turf, roto-till in 20%-30% by volume into the top 2” - 4” of existing soil.
  • In soil-less potting mixes, some plants respond differently to the same ratio. Try small trial batches to determine what mix is best for your plants.
  • Mulching, apply 2” - 4” of Nitrolized Redwood Shavings around planting area and keep several inches away from the trunks. Fine mulches tend to repel water. Using drip irrigation under the mulch can help provide sufficient water to the plants.
