Role of Microalgae as Biofertilizer for Sustainable Plant and Soil Health

Abstract

Soils are the environments used by significant types of organisms, for example, microbes, archaea, algae, fungi, insects, annelids and plants. The wayfaring utilization of different synthetic substances to upgrade agronomic effi-ciency prompted grave outcomes like structural unsteadiness, the assembly of hazardous contaminants and so forth, prompting a biological lopsidedness between soil, vegetation and microbes. Nonetheless, the main job of microalgae and cyanobac-teria to compensate for the yield of plants and other possible arrays stays unexplored yet. The purpose of this chapter is to feature the importance of this novel group of microorganisms with regard to fertility and health of the soil. This interesting group of photosynthetic eukaryotic organisms additionally has solicitations in current farming trends through promising and prolonged nutrient expediency, synchronizing natural carbon and soil fertility and improving plant development and harvest yields, because of incitement of soil microbial enactment. Microalgae are betrothed with the forma-tion of metabolites, for example, growth hormones, polysaccharides, antimicrobial composites and so forth, which undertake a significant job in the plant colonization and multiplication of microbial and eukaryotic organisms in soil.
