Low Carbon Agricultural Fertilizers: 7 Emission-Cutting Tips
“Switching to green ammonia can cut fertilizer-related CO₂ emissions by up to 80%.”
Understanding Low-Carbon Fertilizers
As global awareness about agriculture-related greenhouse gas emissions grows, we must focus on climate-friendly solutions that address the core causes of CO₂ and N₂O release. One of the most promising ways to reduce emissions and build a sustainable food system is by transitioning to low-carbon agricultural fertilizers. These innovative fertilizers are specifically designed to reduce greenhouse gas emissions associated with traditional fertilizer production and use, primarily by replacing fossil fuels with renewable energy sources and integrating cutting-edge technologies.
In this comprehensive blog, we’ll uncover:
- The science and practical strategies behind carbon footprint reduction in agriculture
- The top seven emission-cutting tips every modern farmer should consider
- The benefits and challenges of adopting low-carbon fertilizers
- How tools like Farmonaut’s Carbon Footprinting platform support farm-level emissions tracking for compliance and sustainability
Traditional Fertilizer Emissions: Why Change is Critical?
Traditional fertilizers (especially nitrogen-based fertilizers such as ammonia) are vital for feeding the world’s population. Yet, the production and use of these fertilizers are typically associated with significant CO₂ and N₂O emissions. Traditionally, fertilizer manufacturers rely on natural gas (a fossil fuel) for ammonia synthesis, which contributes significantly to global emissions.
The shift toward low-carbon fertilizers involves:
- Switching to renewable energy in fertilizer manufacturing (hydro, wind, solar power)
- Utilizing climate-friendly fertilizer methods like green ammonia production, enhanced weathering agriculture, and nanotechnology in fertilizers
- Reducing emissions at every stage: from manufacture to field application
“Low-carbon fertilizers can reduce agricultural greenhouse gas emissions by nearly 20% globally.”
7 Emission-Cutting Tips With Low Carbon Fertilizers
Let’s explore practical solutions and methods you can adopt to promote carbon footprint reduction in agriculture. Each of these tips combines new tech, field wisdom, and sustainable fertilizer solutions.
-
1. Switch to Green Ammonia-Based Fertilizers
Green ammonia production transforms fertilizer manufacturing by eliminating fossil fuel dependence. Instead of using natural gas, green ammonia is produced through electrolyzing water with renewable energy (wind, solar, or hydro). Hydrogen from this process is then combined with atmospheric nitrogen to form ammonia–a vital precursor for many chemical fertilizers.
- Impact: This method significantly reduces CO₂ emissions—by as much as 70–90% (Yara International).
- Advantages: Supports a climate-resilient food system and enables large-scale fertilizer decarbonization.
- Implementation: Choose fertilizer suppliers whose products use renewable energy fertilizers and are labeled as “green ammonia derived.”
-
2. Adopt Enhanced Weathering Agriculture Methods
Enhanced weathering involves applying crushed basalt to agricultural soils. The minerals in basalt react with atmospheric CO₂ and water, forming stable carbonates that sequester carbon in solid form while improving soil fertility. This technique not only reduces emissions but also can increase crop yields.
- Environmental co-benefits: Boosts soil health, enhances nutrient cycling, and corrects soil acidity.
- Implementation: Incorporate enhanced weathering via local basalt amendments alongside regular fertilizer routines.
- Research-backed: Enhanced weathering can sequester up to 4 tonnes CO₂e/ha/year, according to arxiv.org.
-
3. Integrate Nanotechnology In Fertilizers For Precision Nutrient Delivery
Nanotechnology in fertilizers leverages nanoparticles (nano fertilizers) to dramatically improve nutrient efficiency and reduce losses. Due to their small size, these particles deliver nutrients directly to plant roots, allowing for maximal absorption and minimizing leaching.
- Reduced nitrous oxide losses: Minimizes N₂O emissions, a potent greenhouse gas.
- Cost savings: Farmers can use less fertilizer for the same (or better) yield results.
- Examples: Nano-urea, nano-phosphate, and micronutrient nano-formulations.

4. Utilize Biofertilizers and Organic Amendments
Biofertilizers are living organisms—microbes such as nitrogen-fixing bacteria, phosphate-solubilizing fungi, or mycorrhizal inoculants—that naturally enhance soil nutrient availability. These climate-friendly fertilizer methods draw upon nature’s processes rather than fossil fuel-based synthesis.
- Decrease reliance on synthetic fertilizers
- Support carbon sequestration and microbial biodiversity
- Low-input, sustainable, and compatible with organic farming systems
Application: Seed treatments, soil applications, or as foliar sprays
Explore Farmonaut’s Traceability System to ensure biofertilizer supply chains are transparent and sustainable from farm to market.
-
5. Employ Enhanced-Efficiency Fertilizers (EEFs)
Enhanced-efficiency fertilizers are formulated to optimize nutrient supply and minimize losses due to volatilization, runoff, or leaching. These include:
- Slow-release nitrogen fertilizers
- Nitrification and urease inhibitors
- Coated or encapsulated fertilizers
By controlling the release of nutrients, EEFs ensure that plants get what they need when they need it, reducing unnecessary applications and associated emissions.
-
6. Optimize Fertilizer Application With Digital Decision Support
Leveraging remote sensing, AI, and satellite data platforms (such as Farmonaut) empowers farmers to apply fertilizers only where and when needed using precise, data-driven recommendations.
- Minimizes over-application/eutrophication
- Supports yield-maximizing and emissions-reducing strategies
- Resource efficiency: Lowers input costs and environmental impact

7. Support On-Farm Renewable Energy Projects For Fertilizer Operations
Farmers can invest in on-site renewable energy (solar panels, wind turbines, or biogas digesters) to power irrigation and fertilizer mixing or blending equipment. This decreases the indirect carbon footprint of fertilizer application and farm operations.
- Promotes energy independence and climate resilience
- May unlock subsidies or carbon credits in certain regions
- Integrates well with Farmonaut’s Crop Loan & Insurance Assessment for sustainable farm investments
