OG Thorvin Nature's Kelp
Mineral-Rich Organic Kelp for Soil, Crops, and Compost Vitality
OG Thorvin Nature's Kelp is a certified organic kelp meal harvested from the pristine waters of Iceland's North Atlantic coast. This dried and milled seaweed (primarily Ascophyllum nodosum) is a powerhouse source of over 70 minerals, micronutrients, natural growth hormones, and plant-available trace elements. It is ideal for use as a soil amendment, compost booster, foliar feed, and livestock supplement in any regenerative, no-till, or organic growing system.
Key Characteristics
-
Supplies Micronutrients and Enhances Plant Resilience
Thorvin kelp is rich in potassium, magnesium, sulfur, boron, iron, and zinc-key elements for chlorophyll production, enzyme activity, flowering, and immune defense. It helps crops withstand drought, transplant shock, disease pressure, and temperature swings. -
Feeds Soil Microbes and Improves Structure
When applied to soil or compost, kelp stimulates microbial activity, humus formation, and nutrient cycling. It enhances soil texture and supports mycorrhizal and bacterial symbioses, building long-term fertility. -
How to Use in Soil, Compost, and Foliar Programs
-
Soil amendment: Apply 1-2 lbs per 100 sq ft or 5-10 lbs per 1,000 sq ft as a topdress or mix-in.
-
Compost: Add 1-2 cups per yard to stimulate microbial breakdown and mineral content.
-
Seedling trays and starts: Mix 1-2 tablespoons per gallon of potting mix.
-
Foliar feed: Brew into compost tea or steep at 1-2 tbsp per gallon of water.
-
-
Supports Rooting, Blooming, and Fruit Set
Natural growth hormones (cytokinins, auxins, gibberellins) enhance root vigor, flowering, and overall plant metabolism. Excellent for tomatoes, peppers, fruit trees, cucurbits, berries, and leafy greens. -
Safe and Versatile Across Systems
Use in greenhouses, raised beds, row gardens, orchards, food forests, compost piles, and livestock systems. Also safe as a trace mineral feed additive for chickens, goats, and other pasture-based animals.
