Currently, sustainable agriculture uses environmentally safe practices such as biofertilization. How Do Biofertilizers Increase Crop Yield? Diverse forms of living beings could applied as biofertilizers to improve soil productivity and it's non-pollution through their biodegradability. These can be, for example, live micro organisms such as bacteria,micro algae and micro fungi but also macroorganisms like macro algas, macrofungi and advanced plants. The biofertilizing agents of living organisms along with their metabolites instead of applying chemical fertilizers will be more extensively developed, as the latter result in heavy metals becoming accumulated in soil. The goal of biofertilizer is to implement sustainable soil-conserving agriculture. This will be a release from, climate change and its consequences, as will also implement the proportion of numerous high pollution-based diseases including cancer, liver and kidney failures, and immune system dysfunction. Biofertilizers from various forms of life spanning the Monera and Plantae kingdoms (bacteria, algae, fungi, and higher plants), were considered in this study. The review aims at promoting the use of such organisms for commercial purposes which contribute significantly in increasing quality of soil nutrients in safe, inexpensive and environmental benign method. Beneficial Effects of Bio-fertilizer Overview. The investigation on biofertizers indicate that the due to eco-friendly nature, bio fertilizers have several advantages particularly in soil health, crops yield and other ecologicacl problems, a global The meta-analysis carried out revealed which biofertilizers endowed in conjunction with characteristics like mobilizing phosphorus and fixing nitrogen significantly improve NUE coupled with crop yield, especially in dryland agriculture, this study underlines the importance of bio-fertilizers as a key input for an ecofriendly and sustainable agriculture to cope with climate change, which could usefully alleviate soil and water limitations (Schutz et al., 2018).
