Seaweed Fertilizers Have an Ancient History

Seaweeds have long been valued as sources of food, medicine, fiber and other materials. Evidence shows that humans ate seaweed as far back as 2500 BCE in China. Long after, the first Hawaiians transitioned from explorers to settlers, learning the value of seaweeds as fertilizers in their coastal taro ponds. But it wasn't until the 1950s that the development of a process to liquefy seaweed would revolutionize its widespread use in agriculture.

Use of seaweeds as an agricultural fertilizer is a common practice in coastal regions of the world. Seaweed is a valuable fertilizer because it contains a wide array of useful molecules. Kelp can include macronutrients like nitrogen, phosphorus and potassium, trace elements (Fe, Cu, Zn, Co, Mo, Mn and Ni), plant hormones (abscisic acid, auxins, cytokinins and gibberellins), hormone-like regulators (betains, brassinosteroids, jasmonates, polyamines and salicylates), vitamins, amino acids and signal peptides. No wonder plants like it so much!!

Directions for Use and Application Rates

How should I use Emerald Cup Kelp?

Directions for Use: Emerald Cup Kelp should be used as part of a comprehensive nutrient management program determined from plant tissue or soil analysis for your specific crop. Apply pre-plant, once per week when plants are actively growing, or more often as needed based on plant genetics, lifecycle stage, and immediate needs. Shelf life is over two years if kept away from moisture.

Mixing Directions: Mix well in the desired amount of water. DO NOT STORE MIXED PRODUCT; only mix enough for immediate application. Emerald Cup Kelp should be compatible with most other fertilizers and plant nutrients. Application of Emerald Cup Kelp with pesticides may reduce expected results. When mixing with other products, perform a jar test for compatibility and spray test on a small area before wider usage.

What is the Emerald Cup Kelp application rate?

Foliar Feeding: We recommend that Emerald Cup Kelp be applied as a foliar feed to plants in any kind of growth medium. Mix 1 to 2 teaspoons of Emerald Cup Kelp per gallon of applied water. Spray mixed product onto stems, branches, and top and underside of leaves until liquid begins to drip, either early or late in the day (avoid spraying in intense heat or direct sun). Do not overspray.

Drench Feeding: In a soil or soilless system or where foliar feeding is not possible, apply Emerald Cup Kelp as a root drench. Mix 1 to 2 teaspoons of Emerald Cup Kelp per gallon of applied water. Soak at least 2” of soil by pouring a steady stream of mixed product around the base of the plant. 

Hydroponic Systems: Mix 1 to 2 teaspoons of Emerald Cup Kelp per gallon of reservoir water.
