A market that didn’t exist earlier is now worth billions.
According to a report by Straits Research published in 2024, it is estimated that the market value of global biofertilizers will be just over $2 billion (USD) in 2024 and will reach nearly $5.7 billion (USD) by 2033, with a compound annual growth rate (CAGR) of 12.23%.
This is not a temporary trend but rather a transformational shift in how the globe views food production.
The chart provides a clear visual picture of what is currently happening in the global biofertilizer industry, but the real story is found in the “Why” behind the chart.
Problem With the Old Ways
In the last several decades, massive amounts of pesticide and synthetic fertilizer use have caused worldwide degradation of soils leading to reduced soil fertility via loss of biodiversity, decreased water retention, and the disruption of biogeochemical cycles. On the other hand, the world’s population is projected to reach 9 billion by the year 2050, requiring enormous increases in crop yields in order to satisfy basic food demand.
Chemical fertilizers were developed to propel the Green Revolution, but it has come at an expense and the cost has yet to be paid. Fertilizer nitrogen runoff contaminates water systems. Nitrous oxide which is a greenhouse gas that is 300 times more efficient at trapping heat than CO₂ that escapes from over-fertilized fields. The most subtle effect of fertilizer destruction is that the soils themselves are beginning to perish.
Let’s Talk About Microbes
Living organisms are used to create biofertilizers, such as bacteria, fungi, and algae, that give significant benefits when they form a cooperative relationship with plant roots. They have the unique ability to assist in acquiring essential nutrients from the air and soil (that would not normally be available to the plant) via their association/partnership with plant roots.
Biofertilizers created from naturally occurring bacteria, fungi, and algae are also capable of improving soil fertility, so that plants (through their roots) can access the nutrients necessary to grow as intended, and do so in a way that aligns with sustainable agriculture practices (ScienceDirect).
One of the most well-known cooperative partnerships that biofertilizers encourage between plants and microbes involves Rhizobia bacteria and the Legume family of plants. Through their ability to use microorganisms as a tool for growing plants and reducing chemical dependency on synthetically made nitrogen fertilizers, biofertilizers derived from these types of organisms have increased soil fertility, increased crop yields, and have been proven to positively impact agriculture.
Research conducted in 2024 found that approximately 58.1% to 84.9% of the nitrogen uptake by hairy vetch came from the process of nitrogen fixation by bacteria, providing a significant increase in crop yield and a reduced amount of nitrous oxide emissions from paddy field cropping.
This is not a minor impact of one type of organism acting as the chemical factory for producing plant nutrients for free.
What the latest science says
In a report published in Discover Agriculture by Springer Nature, researchers conducted an extensive evaluation of all mechanisms of biofertilizers and found that endophyte enriched formulations performed significantly better than their rhizosphere-only counterparts in areas where soil is depleted of minerals. Additionally, endophyte enhanced formulations produced 12-25% greater yield compared to rhizosphere only formulations based on crop type and soil characteristics, demonstrating consistent efficacy across cropping systems.
New genomic technologies have also accelerated advancements. Specifically, through advancements in genetic editing and transcriptomics, researchers have identified many of the important biosynthetic pathways of rhizobacteria that are involved in modulating various plant hormones including auxin, gibberellin, cytokinin and ethylene. Engineered strains of rhizobacteria will not only enhance crop nutrition but will also reduce or eliminate the effects of plant diseases. For example, Pseudomonas koreensis has demonstrated the ability to inhibit disease-causing organisms from infecting maize through the production of both antioxidant enzymes and siderophores.
One example of the success of biofertilizers on a national level can be found in China. As of 2024, China is home to more than 3,500 biofertilizer manufacturers who produce approximately 35 million tons of biofertilizers annually and apply them to more than 20 million hectares of land used for many different types of crops within its borders.
The climate story here that deserves more attention
While crop yields are important, there’s also a significant climate-related aspect that needs more focus. Microbial organisms that suppress methane emissions from paddy soils and nitrous oxide from upland systems are being genetically engineered (using CRISPR-Cas9) for improved ability to withstand extreme variations in carbon dioxide (CO₂) and temperature (as a result of climate change) [Research Gate].
Agriculture comprises approximately 10–12% of global greenhouse gas (GHG) emissions, and there are bio-fertilizers being produced that could help reduce these levels while simultaneously helping to feed the world. This represents a unique opportunity to achieve an outstanding twofold benefit.
Challenges that must be acknowledged
Biofertilizers have real-world barriers like poor performance from one location to another, limited product shelf-life, sensitivity to extreme conditions, and, simply put, not many farmers know what they are.
In China, only 1-3% of soybean crops are planted with rhizobial inoculants (PubMed) have an uphill battle to overcome the adoption gap. Getting these types of solutions to work on a large scale will require an organised effort to develop standards, educate farmers, and create supportive policies. There are education campaigns and training opportunities being developed to help promote the benefits of biofertilizers, but that just a start of the work to be done.
The Bottom Line
There is more to the soil in a field than just dirt. It’s an entire community of organisms that are involved in cycling nutrients, protecting the roots of the plants, and ultimately creating the foundation for every meal we eat. Biofertilizers are not creating a new soil system rather, they are utilizing this pre-existing soil system.
In the traditional agricultural model, farmers treated soil like a sponge that could hold lots of chemical applications without being alive. With the new agricultural model, farmers are treating soil as it was meant to be treated which is like it is actually alive. When farmers invest in the soil and take care of the soil, it provides compounding returns over time. The smallest farmers on earth (microorganisms) have been doing this for 400 million years, we are now just learning how to work with these little farmers on the soil.
Frequently Asked Questions
Q1: Can biofertilizers completely replace chemical fertilizers?
Not yet, although there is hope for some reduction in the future. Research indicates that biofertilizers function well only as part of an integrated nutrient management strategy that involves gradual elimination of chemical compounds. Biofertilizers are best utilized together with small amounts of chemical fertilizer, particularly on poor-quality soils.
Q2: Are biofertilizers safe for human consumption and the environment?
Absolutely! They represent some of the safest agricultural inputs known. There is no danger of residues since biofertilizers consist of natural microorganisms only; thus, crops produced with them are free from chemical contaminants. Furthermore, biofertilizers increase soil biodiversity, which in turn leads to improved water quality.
Q3: Which crops benefit most from biofertilizers?
Biofertilizers have been shown to yield spectacular results on leguminous plants such as soybean, chickpeas, lentils, and alfalfa. However, cereals like wheat, maize, and rice also exhibit considerable productivity increases with appropriate inoculation of crops with phosphate and potassium solubilizers.
