SeaLife Kelp Meal for Soils

seaweed soil amendment

SeaLife Kelp Meal for Soils is a graded kelp meal soil conditioner made from the seaweed Ascophyllum nodosum. We harvest the seaweed from the cold, clean waters of the Maine coast and dry it at low temperatures to preserve its valuable vitamins, minerals, trace elements, amino acids, and carbohydrates. The variety of nutrients in SeaLife feed and stimulate beneficial microbial populations in your soil, improving soil tilth and ultimately plant health and performance.

If you’re looking for a slow-release soil conditioner to amplify the health of your soil, this is it!

Repeated applications will gradually improve soil texture, structure, aeration, and water and nutrient holding capacity as SeaLife provides the organic matter and nutrients necessary for a healthy soil microbial community. A healthy soil microbial community increases fertility and makes essential amino acids available to plants, while also suppressing the growth of other potentially harmful microbes.
