Azolla fern that will save the world by reducing global temperatures


This ancient fern plant known as Azolla filiculoides is a small aquatic evergreen plant. Azolla filiculoides proliferates swiftly by budding and growing a thick network on the water surface.

Researchers simply made it the primary fern to get its genome sequenced due to its potential for lowering global temperatures. Scientists hope to use this fern to invert the global warming effects.

Fifty million years back, it was so rich as sea bloom that it helped cool the world's climate.

Azolla fern that will save the world by reducing global temperatures

Fifty-five million years back, when researchers assume the Earth was in a chaotic state, perilously overheated by ozone-depleting substances, the Arctic Ocean was an altogether different place.

It was a huge lake, associated with the more prominent seas by an opening: the Turgay Sea.

At the point when this channel shut or was blocked about 50 million years prior, the encased waterway turned into the ideal living space for a little-leaved fern called Azolla.

Envision the Arctic like the Dead Sea of today: It was a hot lake that had turned out to be stratified, experiencing an absence of trade with outside waters.

That implied its waters were stacked with abundance supplements.


How Azolla Fern helped in lowering global temperature


Azolla fern exploited the rich nitrogen and carbon dioxide, two of its most loved nourishments, and thrived. Huge populaces framed thick tangles that secured the body of the lake.

At the point when precipitation expanded from the evolving atmosphere, flooding gave a thin layer of crisp water for Azolla to crawl outward, finished parts of the encompassing landmasses.

The way that the fern just needs a little an inch of water under it to develop influences the entire situation to appear to be simply inside reason—that is, until the point that you figure out how much carbon this carbon eager for dioxide plant sucked up finished the course of those million years.

Amid the Azolla major bloom, worldwide temperatures dove, proposing the minute fern "assumed a key part in changing Earth from a hothouse to the cool place it is today.


Azolla event

This incredible Azolla fern boom was thriving to the point that it went on for a long time, and is currently referred to paleobotanists as the "Azolla event." 

Green plants suck up carbon dioxide; & it is especially great at doing as such. Over that period, specialists trust it sequestered around 10 trillion tons of carbon dioxide people presently discharge into the air each year.

Yet, Azolla's evident trove of helpful characteristics does not stop there: The plant's shape contains concentrated little indents where it houses cyanobacteria, a type of blue-green algae that goes about as a nitrogen fixer—that is, changing over nitrogen in the air into a compost.

The fern has the microbes, giving it sugary fuel, and in doing as such, helps make its own compost.
Agriculturists all through Asia, especially in China and Vietnam, definitely realized that they have utilized Asian water fern as a type of compost in rice fields for over 1,000 years. In their Nature Plants paper.

 Green manure of Azolla


In this technique, Azolla biomass is joined into the field before rice plantation.

It very well may be either developed in a similar field before transplanting rice or developed in nursery informal lodging transported and consolidated into the field by puddling.

When it is fused into the dirt, breaks down quickly with 7-10 days. Notwithstanding, nitrogen accessibility reaches out from multi-week to ten weeks. 

Research has demonstrated that 34% of the aggregate nitrogen is accessible two weeks after fuse, 63% following a month, 76% following a month and a half and 85% following two months.

This strategy includes developing Azolla alongside rice edit. Multi-week after the planting of rice seedlings, new Azolla t the rate of 200-300 gm for every square meter ought to be connected in standing yields. the fern biomass is shaped in three weeks.

Water is depleted out and Azolla is consolidated into the dirt utilizing executes.

"With this first genomic information from ferns, science can increase imperative knowledge for understanding plant qualities

Azolla cultivation methods


Azolla is a little fern with a spreading stem and bilobed clears out. The roots that rise up out of the stem assist the plants with floating on water. It is by and large discovered drifting on stale water.

There is a little pit on the uppermost piece of the leaf which houses upwards of 80,000 blue-green algae have the ability to settle air nitrogen and make it accessible to Azolla.

Consequently, the blue-green growth gets asylum and sustenance from the fern and blue-green growth.


Under this technique, a lake or a field with shallow standing water is picked. The profundity of water required for Azolla cultivation differs between 5-10 cms.

For the quick development of Azolla, the use of superphosphate (4-8 kg P2 O5/ha) is prescribed. Azola inoculum can be presented in standing water moreover. In three weeks time, it increases to frame a cover on the water surface, which can be gathered and utilized instantly or dried and protected for later utilize
