Rice Hulls

Product Overview

Rice hulls are the hard outer covering, or husk, of the rice kernel—composed of silica and lignin and indigestible to humans. In agriculture and horticulture, these lightweight byproducts offer diverse benefits in seeding, soil amendment, bedding, erosion control, and insulation.

• Weigh approximately 9 lb per bushel—use standard calibration for seeding equipment
• Improves seed flow: ensures uniform coverage, slows seed drill rates, prevents “bridging” of fluffy seeds
• Enhances soil structure: increases aeration, drainage, and moisture retention in potting mixes and garden beds :contentReference[oaicite:0]{index=0}
• Organic, biodegradable substrate safe for hydroponics, composting, and vermiculture :contentReference[oaicite:1]{index=1}
• Ideal animal bedding and litter—highly absorbent and anti-skid; used in poultry and livestock operations :contentReference[oaicite:2]{index=2}
• Effective insulation: used in natural building, compost bins, and thermal panels :contentReference[oaicite:3]{index=3}
• Many additional uses: compost bulking agent, biochar feedstock, soil amendment, construction filler, filter media :contentReference[oaicite:4]{index=4}

Rice hulls are neutral in pH, naturally resistant to mold, and decompose slowly—making them a sustainable, eco-friendly alternative to mined materials like perlite or pumice :contentReference[oaicite:5]{index=5}.

Directions

For Seeding: Mix with seed at 9 lb per bushel. Calibrate drill settings to account for added bulk and weight.

As Soil Amendment/Substrate:

• Mix into potting soil or garden beds (10–50%) to enhance drainage and aeration;
• Use parboiled or sterilized rice hulls in hydroponic media for inert, stable support;
• Add during composting or vermiculture as a bulking agent—helps airflow and water balance.

Animal Bedding & Litter: Spread dry hulls in animal pens for absorbent, anti-skid bedding. Replace as needed to maintain dryness and cleanliness.

Insulation & Erosion Control: Use loose or mixed with natural binders in building, compost bin insulation, trail surfaces, or as mulch to reduce erosion and provide thermal buffering.
