SeaXtra Nutritional Supplement (1-0-3) provides nutrients from urea, potassium acetate and seaweed extracts derived from the highest quality Ascophyllum nodosum. This hardy seaweed is sourced from the cold, nutrient rich waters of the Bay of Fundy. Thriving in intertidal zones, this seaweed is constantly exposed to a variety of environmental stresses. As tides change throughout the day, the seaweed goes from being completely exposed on the rocky shoreline to submerged beneath the frigid salt waters of the North Atlantic. To survive these environmental extremes, the seaweed contains a variety of beneficial bioactive substances including, amino acids, vitamins, enzymes, proteins, minerals, etc.
When applied to plants, the components in SeaXtra Nutritional Supplement have been known to encourage rooting and help improve stress tolerance. SeaXtra also provides a unique source of organic content that improves soil microbial activity. These benefits are particularly advantageous for new plantings and to promote the vitality of existing plants.
- Landscapes prone to environmental stresses including temperature extremes and drought
- Shallow or poorly developed root systems
- Weak or thin areas in turf
- Poor microbial activity
