Seaweed or kelp meal fertilizer makes a great organic amendment to garden soil. It’s an excellent bioactivator, waking up all the microbes in the soil to help break down organic matter and make it available to plants. It also contains macro and micro nutrients, trace elements, and vital resources. Whether you live on the coast or inland you can add kelp meal fertilizer to the garden.
The Basics of Kelp Meal Fertilizer
Kelp is a type of seaweed that’s harvested in the oceans or along the shore from seaweed that washes ashore. Some people call any seaweed kelp, but kelp refers to one specific type of aquatic plant.
Why Kelp Fertilizer Is Great for Gardens
Organic gardeners love to compost plant material such as grass clippings, leaves, vegetable peels and others to create a rich, organic fertilizer. Out of all the plant material available, organic gardeners swear by seaweed and kelp meal fertilizer for many reasons.
- Abundant source of bioactivators: Bioactivators are organic (living) materials that help break down other materials. In the case of compost piles and garden waste, bioactivators trigger the biological process of decomposition. If they’re abundant in the soil, they do several things. First, they break down the remains of plants into their chemical components, which makes them available in a form plants can use in the garden. By breaking down plant material, they also enhance the soil structure. They can also be added to existing compost piles if the pile isn’t decomposing quickly to trigger the natural process of decomposition.
- Rich source of NPK: NPK stands for nitrogen, phosphorus and potassium, the major three elements found in every type of fertilizer and the macro nutrients plants need to survive. Kelp meal fertilizer tends to have slightly more potassium than other fertilizers, which helps plants develop strong roots.
- Include micro nutrients and trace elements: Kelp and seaweed contain an abundant amount of various micro nutrients and trace elements. These are absorbed through seawater and made available when the kelp and seaweed breaks down again in soil.
- Breaks down quickly: When added to the compost pile or garden, kelp in its natural, harvested form breaks down more quickly than grass clippings or leaves.
- Sustainable source of fertilizer: Kelp grows quickly in the oceans, and while over harvesting can be a problem, most kelp is gathered at the shore. If you live near the beach and it is legal in your area, you can gather up as much kelp and seaweed as washes ashore and take it home to your compost pile. Just be sure to check local laws to make sure you are not illegally harvesting something from a state park or a protected area.
- Completely organic: It’s 100 percent organic, and an excellent soil-builder for organic vegetable gardens.
