SOIL AMENDMENTS and COMPOST

FIR BARK HUMUS - soil amendment for alkaline sandy soils

Base feed stock for Fir Bark Humus comes from Douglas fir trees grown in the Pacific North West.  Fir Bark Humus is derived from the part of the logging/milling process in which bark is removed from the tree. After the debarking takes place, the bark is then passed through various sized vibrating screens which separate the bark into different sizes including 1/4 inch fir bark humus.  It has a slightly acidic pH value and will aid in moving alkaline soil toward a neutral value.  Fir Bark has a slower decomposition rate than shavings derived from soft woods such as Pine.  Fir Bark Humus is a stand-alone amendment but can also be used as a component in container mixes or soil-less potting mixes.

Coco-Coir - soil conditioner 

Our Coco-Coir is a renewable, non synthetic coconut by-product rich in potassium and micronutrients. Used as a soil conditioner it naturally guards against plant diseases and increases nutrient uptake, which results in explosive root and plant development. Our Coco-Coir also improves soil structure, helps prevents soil compaction, holds seven to eight times its weight in water, and provides improved drainage and aeration.  


NITROLIZED FIR SHAVINGS - soil amendment for sandy soils 

Nitrolized Fir Shavings are derived from construction grade Douglas fir building remnants.  The fir shavings are "nitrolized" (treated) with ammonium nitrate 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 Shavings improve soil structure, increase nutrient holding capacity of sandy soils, and improve water drainage.  Nitrolized Fir Shavings are a stand-alone amendment but can also be used as a component in container mixes or soil-less potting mixes.
