Resumo(s)
Seaweed has long been known to be an effective fertilizer improving soil quality
and also a biostimulant of plant growth. Seaweed contains all the macro and micronutrients
needed for plant growth (Verkleij 1992). Also, it has nitrogen (N) content
similar to that of most animal manures, high content in potassium (K) (especially
brown seaweed) and a modest amount of phosphorus (P) (Stephenson 1974; Senn
and Kingman 1978). Seaweed improves soil quality, mainly as a result of its high
content in phycocolloids resulting in increased structure, water retention and
exchange capacity (Metting et!al. 1990; Lynn 1972; Khan et!al. 2009). By virtue of
its high Calcium (Ca) content and the presence of alginates capable of binding aluminium,
seaweeds additionally have liming effects (Crouch et! al. 1990; López-
Mosquera and Pazos 1997; Eyras et! al. 1998). Also, it facilitates the growth of
bene"cial microbiota, thereby increasing biological activity in soil (Kuwada et!al.
2000, 2006; Chen et!al. 2003; Khan et!al. 2009).
