Seaweed  Fertilizer

Seaweed has been used as a fertilizer by the farming Community in the rich green fields of the West of Ireland for many years.  Farmers harvested the seaweed from the rugged shores and applied the seaweed direct onto their grasslands, such was their rich harvest that this was repeated rather than any other fertilizer. 

Celtic Moss has three types of Seaweed:

  • Seaweed Fertilizer 
  • Seaweed Liquid Fertilizer

Seaweed contains all major plant nutrients and trace elements; Alginic acid, Vitamins,  Auxins and Antibiotics. Alginic acid is a soil conditioner, the remainder are plant conditioners. 

Seaweed and seaweed products improve the water holding characteristics of soil and help the soil to form a more crumb structure.  It was found that farmers on the rugged slopes of the west of Ireland used seaweed fertilizer as other fertilizer was washed down the slopes by the heavy rainfall they experienced from the North Atlantic weather, however the use of fertilizer created a  stronger crumb on the soil surface and prevented rainfall carrying off fertilizer and seeds. 

Today seaweed liquid  is used by large growers, at home in the garden, on the golf course, on the race course to name just a few.
