People have used seaweeds for millennia as
a nutrient for animals and soils health. For the
applications on soils and plants, seaweeds act
as a biostimulant, mainly because of the presence
of plant hormones. A significant amount of research
shows that seaweeds in plants culture has a
positive effect on crops. Seaweed extracts improve
the resistance of the plant to drought and frost and
increase crops yield.
