Rice Hulls (PBH)A sustainable and effective soil amendment, rice hulls improve drainage and aeration while helping soil retain just the right amount of moisture. Ideal for loosening heavy soils or balancing rich compost blends, they also make an excellent mulch, naturally suppressing weeds without compacting. Rich in silica and slow to break down, rice hulls support soil structure, microbial activity, and long-term plant health. pH neutral and chemical-free, they’re a smart, regenerative choice for gardeners and growers.

Improve Drainage and Aeration

• Rice hulls are lightweight and help create air pockets in soil, improving root oxygenation.

• Great for loosening heavy clay soils or balancing out water retention in compost-heavy beds.

Retain Moisture (Just the Right Amount)

• They hold moisture like a sponge but also let excess water drain, creating a well-balanced root zone.

Suppress Weeds

• When used as mulch, rice hulls form a loose but effective weed barrier while allowing water to pass through.

Slowly Decompose and Add Organic Matter

• Unlike fast-decaying materials, rice hulls break down gradually, feeding soil microbes over time and improving soil structure.

Silica Content

• Rice hulls are rich in silica, which can strengthen plant cell walls—some studies suggest this helps improve pest and disease resistance, especially in grains and grasses.

pH Neutral and Non-Toxic

• Unlike some amendments, rice hulls are pH neutral and free from salts or harmful residues, making them safe for all kinds of crops.

Sustainable and Renewable

• They’re a byproduct of rice production, so using them recycles agricultural waste and supports sustainable farming syste
