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