Abstract
Microalgae are tiny microscopic prokaryotic and eukaryotic organisms that serve as a partial substitute for conventional synthetic fertilizers. The application of microalgae as biofertilizers and biostimulants has been shown to positively influence both the above- and below-ground growth of plants. Rich fertile land is an essential resource for farmers. Nevertheless, the poor farming practices can lead to soil degradation and loss of nutrients. The efficacy of microalgal biofertilizer and biostimulants is greatly influenced by a number of critical factors. The method of application and their combinations with organic amendments result in their distinct effects depending on the crop and the desired outcome. Concentration and dosage play vital roles; as a general rule, low to moderate concentrations are effective, while high concentrations may produce inconsistent and even harmful results on plant growth and physiology. This review article studies last five years of research from onwards and provides a brief review of the microalgae applications across crops, highlights mechanisms, identifies key knowledge gaps and future perspectives for research
