Long-term Advantages of Lignite-Granulated Fertiliser

Australia's agricultural sector faces significant challenges due to its nutrient-poor and heavily weathered soils. These soils suffer from issues like erosion, salinity, and acidity, which are exacerbated by an overreliance on conventional fertilisers and extensive land clearing. Despite these challenges, Australia maintains high farm productivity. Recognising the critical importance of soil health, the government has emphasised soil as a "national asset" and aims to promote best practices through a comprehensive soil improvement plan.

In collaboration with ESG Agriculture, we are developing a granulated lignite-urea product that substantially benefits farmers and the environment. This innovative fertiliser addresses the key issues facing Australian soils and promotes sustainable farming practices. Here’s an in-depth look at how it helps:

Slow-Release: Ensuring Consistent Nutrient Supply

One of the most significant advantages of lignite-granulated fertiliser is its slow-release mechanism. Traditional fertilisers often release nutrients too quickly, which can lead to nutrient burn and inefficient nutrient uptake by plants. In contrast, the slow-release property of lignite-granulated fertiliser ensures a steady and consistent supply of nutrients. This gradual release aligns with the natural growth cycles of plants, promoting steady and healthy plant growth without the risk of nutrient burn.

Benefits of Slow-Release Fertiliser:

  • Enhanced Nutrient Efficiency: Plants receive nutrients at a pace they can absorb, minimising waste.
  • Reduced Risk of Nutrient Burn: Gradual nutrient release prevents the damage that can occur with high concentrations of nutrients.
  • Improved Plant Health: Consistent nutrient availability supports robust plant development and resilience against stress.

Lower Nitrogen Emissions: Supporting Environmental Health

Nitrogen is a critical nutrient for plant growth, but its excessive use in agriculture can lead to significant environmental issues. Traditional nitrogen fertilisers often produce high nitrogen emissions, contributing to environmental pollution. Lignite-granulated fertiliser dramatically reduces nitrogen emissions, supporting environmental health and sustainability.

Environmental Benefits:

  • Reduced Greenhouse Gas Emissions: Lower nitrogen emissions contribute to mitigating climate change.
  • Minimised Water Pollution: Reduced nitrogen runoff into water bodies prevents eutrophication and protects aquatic ecosystems.
  • Sustainable Farming Practices: Promoting environmentally friendly fertilisers aligns with broader sustainability goals.

Reduced Urea Usage: Cost Savings for Farmers

The slow-release formula of lignite-granulated fertiliser means that less urea is needed to achieve the desired nutrient levels in the soil. This reduction in urea usage translates to significant cost savings for farmers. Farmers can achieve better economic efficiency and improve their bottom line by optimising nutrient delivery and minimising waste.

Economic Advantages:

  • Lower Input Costs: Reduced need for frequent fertiliser applications saves money on purchasing and applying fertilisers.
  • Increased Profit Margins: Lower input costs can increase farmer profit margins.
  • Sustainable Investment: Investing in slow-release fertilisers provides long-term economic benefits by enhancing soil health and productivity.

Long-Term Soil Health: Enhancing Soil Structure and Fertility

Healthy soil is the foundation of productive and sustainable agriculture. Lignite-granulated fertiliser enhances soil structure and fertility, contributing to long-term soil health. This fertiliser supports the creation of long-term carbon stores, improving soil organic matter and promoting sustainable farming practices.

Benefits to Soil Health:

  • Improved Soil Structure: Enhanced soil aggregation and porosity promote better root growth and water infiltration.
  • Increased Soil Fertility: Higher soil organic matter levels improve nutrient availability and retention.
  • Carbon Sequestration: Long-term carbon storage in the soil helps mitigate climate change by reducing atmospheric CO2 levels.

Embracing Innovation for a Sustainable Future

The collaboration between our team and ESG Agriculture—enabled by our COLDry process—represents a significant step forward in addressing Australian agriculture's challenges. By adopting lignite-granulated fertiliser, farmers can maintain crop yields, reduce environmental impact, and contribute to the agricultural sector's sustainability. This innovative approach aligns with the government’s vision of treating soil as a national asset and promoting best practices for soil management.

Using lignite for agricultural applications means this vast resource can enhance rather than harm our environment, pivoting its use away from high-emission power generation toward soil health and food security.


The long-term advantages of lignite-granulated fertiliser are clear. Its slow-release mechanism ensures a consistent nutrient supply, reducing the risk of nutrient burn and improving plant health. Lower nitrogen emissions support environmental sustainability, while reduced urea usage translates to significant cost savings for farmers. Most importantly, this fertiliser enhances soil structure and fertility, creating long-term carbon stores and promoting sustainable farming practices.

As we look towards the future, embracing innovations that support sustainable and productive agriculture is essential. We can cultivate a more sustainable and prosperous future for Australian agriculture by working together and adopting best practices.

Join us in embracing this innovation, and together, let's cultivate a more sustainable and productive future.
