Abstract
Seaweed is considered the most important marine bioresource within
marine ecology, enriched with ideal bioactive components, including macro and
micronutrients, vitamins, amino acids, proteins, phytohormones, minerals, lipids,
carbohydrates, antimicrobial compounds, and osmoprotectants. Currently, seaweed is a
potential candidate for the production of human food, animal feed, fuels, fertilizers,
chemicals, pharmaceuticals, phytoremediation, nutraceuticals, and hydrocolloids.
Within the agricultural sector, seaweed-derived biofertilizers play a vital role. The
utilization of seaweed compounds in agriculture and horticulture to nourish and
condition the soil, as well as for the enhancement of pest management, are some of the
major considerations that have enhanced the growth of the worldwide seaweed extracts
market. Seaweed extracts are available as biofertilizers in various forms, including
liquid fertilizers, powder, and flakes. In this chapter, our goal is to emphasize the
utilization of seaweed-derived biofertilizers in sustainable agriculture and its
significance in organic farming, which is a more environmentally friendly option for
current and upcoming generations.
