Seaweed garden nutrients are relatively low in nitrogen and phosphorus but contain about 60 other trace elements, as well as fungal and disease preventatives. Using seaweed for compost improves soil consistency and increases water retention in sandy or grainy soils and may be used as a top or side dressing.
