Gaia Kelp Meal 1-0-3 Soil Amendment is a fast-acting source of potassium and vital micro-nutrients. Don’t look to kelp products for the high Nitrogen-Phosphorus-Potassium ratings that you’ll see on other fertilizers in this section. It is the micronutrients found in kelp that make it such a useful soil amendment. Kelp Meal forms cross-linked organic chelates with nutrients, protecting them from loss by leaching and making them readily available for plant uptake. Many species of seaweed have been used in agriculture and large differences of nutritive values exist among them. As with many natural soil amendments, Gaia Kelp Meal 1-0-3 Soil Amendment continues to provide benefit for years after initial application.
