Royal Gold Worm Casting, 1 cu ft

Royal Gold® Earthworm Castings 1cu ft — Premium OMRI Listed Vermicompost

Royal Gold® Earthworm Castings are a premium-grade vermicompost sourced and processed to the exacting quality standards that have made Royal Gold a trusted name in professional growing media. Pure worm castings are widely recognized as one of nature's most complete and biologically active soil amendments — naturally rich in plant-available macro and micronutrients, a diverse community of beneficial microorganisms, humic and fulvic acids, enzymes, and naturally occurring plant growth-promoting compounds. OMRI Listed® for use in certified organic production, Royal Gold® Earthworm Castings deliver all of these benefits in a consistent, professionally processed format.

Unlike raw compost or synthetic fertilizers, earthworm castings provide nutrients in forms that are immediately available to plant roots while also feeding the living biology of the growing medium for sustained nutritional release over time. The exceptionally stable structure of worm castings also improves growing media aeration, water retention, and drainage — contributing to optimal root zone conditions throughout the growing cycle.

Key Features & Benefits

• OMRI Listed® Certified Organic: Approved for use in certified organic production. Royal Gold® Earthworm Castings are derived from a pure, vermicompost process with no synthetic inputs, meeting the strict requirements of the Organic Materials Review Institute.
• Naturally Rich Plant Nutrition: Worm castings contain a balanced array of plant-available macro and micronutrients released through microbial activity — providing gentle, biologically buffered nutrition that feeds plants consistently without the risk of salt burn associated with synthetic fertilizers.
• Beneficial Microbial Community: The vermicompost process concentrates a diverse and active community of beneficial bacteria, fungi, and other soil organisms within each casting. Introducing worm castings to your growing medium directly inoculates it with this rich biological community, supporting healthy root zone ecology throughout the crop cycle.
• Humic & Fulvic Acids: Worm castings are naturally rich in humic and fulvic acids that improve nutrient availability, enhance root cell membrane permeability, and stimulate plant growth at the biochemical level — contributing to improved nutrient uptake efficiency.
• Growing Media Structure Improvement: The stable aggregated structure of earthworm castings improves moisture retention and aeration in growing media — helping maintain the optimal air-to-water ratio in the root zone for vigorous plant growth.
• Compost Tea Ready: Royal Gold® Earthworm Castings can be used as an extract base for aerated compost teas, providing a concentrated source of beneficial biology and soluble organic nutrients for foliar or root drench applications.
