Biofertilizers are gaining massive traction across the globe with their eco-friendly nature and abundance of benefits

 

Biofertilizers

The agriculture industry has witnessed a significant change over the years from using conventional machines to GPS-enabled harvesters. Similarly, fertilizers have witnessed continuous progression over the period with biofertilizers gaining significant traction recently. Biofertilizers area unit natural and fertilizer that helps to stay within the soil with all the nutrients and live microorganisms needed for the advantages of the plants. It's employed in organic farming, property agriculture, inexperienced farming, and nonpollution farming. It's additionally one among the vital parts of integrated nutrient management, as they're a cheap and renewable supply of plant nutrients to supplement the chemical fertilizers for property agriculture. The aim of biofertilizers is to enrich and, wherever applicable, replace typical chemical fertilizers so their use will be reduced with the ensuing economic and environmental advantages.

Azotobacter, Azospirillum, Rhizobium, eubacteria, phosphorus, and K solubilizing microorganisms and mycorrhizae area unit a number of the PGPRs that were found to extend within the soil beneath no-tillage or minimum tillage treatment.  There are different types of biofertilizers used namely nitrogen fixing biofertilizers, phosphate biofertilizers, phosphorus mobilizing biofertilizers, compost, etc. Phosphate biofertilizers solubilize the insoluble phosphate from organic and inorganic sources of phosphate. It further releases insoluble phosphorus in soil and fixes in clay minerals. Besides, it lowers pH and secretes organic acids to dissolve bound phosphates in soil. Furthermore, compost is another popular biofertilizer that uses animal dung to enrich with microorganisms, phosphate solubilizing bacteria, eco-friendly organic fertilizer, and various decomposing fungi.

These biofertilizers have shown the positive impact on agricultural activities by fixing nutrients availability in the soil, producing a larger quality of crops, and promoting healthy soil. Liquid biofertilizer is another special type of fertilizer that uses microorganisms to fix atmospheric nitrogen and solubilize insoluble phosphates. Recently, the demand for such fertilizers has increased in the U.S., Italy, and the U.K. Furthermore, in India, the scientists at Bihar Agricultural University (BAU) developed eco-friendly liquid biofertilizers to boost agricultural yield by over 20%.
