Potential Applications of Algae-Based Bio-fertilizer

Abstract

To meet the growing demand for food, the production and application of synthetic fertilizers, pesticides, and other chemicals have intensified, which consequently pollute the environment and pose a serious threat to all living beings. Furthermore, agricultural land is losing its fertility due to intensive agricultural practices and climate changes. Various microorganisms such as bacteria, algae, fungi, etc. are receiving much attention as environmental-friendly alternatives to synthetic chemicals because of their ability to improve the soil fertility, fix atmospheric nitrogen for plant availability, produce plant growth hormones and biocides, etc. This chapter will explore the potential role of microalgae and cyanobacteria as bio-fertilizers.
