LCA study of Humics from Extraction to the Point of Delivery in the UK

The Scientific Case for Humic Soil Boosters

SoilPoint’s humic soil boosters enhance soil health by improving its structure, increasing nutrient uptake, and boosting microbial activity, and can also significantly reduce greenhouse gas emissions in agriculture.

SoilPoint’s soil boosters have a significantly lower Global Warming Potential (174.4 kg CO2 eq) compared to nitrate fertilizers (751 kg CO2 eq) and compound fertilizers (862 kg CO2 eq).  

These findings, from an independent Life Cycle Assessment (LCA) conducted by Earthhood, conclude that humic soil boosters help create healthier soil ecosystems by improving soil organic matter, enhancing nutrient retention and reducing heavy metal contamination. The use of humic soil boosters was shown through this study to mitigate the negative impacts of using synthetic fertilisers, improving soil, water and air quality.

With 80% of the GWP from SoilPoint’s humic soil boosters used in the UK due to current transportation methods, the carbon footprint can be reduced even further through supply chain reforms.  

The report concluded that humic soil boosters have the potential to play a pivotal role in achieving global food security while preserving the environment. The overarching message is that it is no longer good enough to feed our plants, we must feed our soil to feed our growing populations. The adoption of humic soil boosters, such as SoilPoint’s Soil Booster will help achieve this goal.

Background to the Lifecycle Assessment study

In 2024, SoilPoint commissioned a Life Cycle Assessment (LCA) study of its humic soil booster derived from oxidized lignite brown coal, from production to delivery in the UK.  

The study compares these soil boosters with conventional nitrate-based and compound fertilizers to assess their environmental impacts. Undertaken by Earthhood, a carbon offset auditing company accredited by the United Nations Convention on Climate Change, the report highlights the critical need to reconcile agricultural productivity with environmental sustainability to ensure future global food security.  

The report found that the over-reliance on synthetic fertilisers to boost crop yields has led to significant environmental and health challenges, their over-use resulting in soil degradation, water pollution, greenhouse gas emissions, and biodiversity loss. With nutrient demand set to triple by the mid-21st century causing demand for organic soil amendments to grow, traditional methods are insufficient and damaging long term.  

Low-rank coal (LRC) and its derivatives offer a promising alternative to improve soil health naturally. Rich in macro- and microelements, LCR-derived Humic Substances improve soil structure, soil fertility, water retention, nutrient retention, while reducing soil degradation. It also helps with soil remediation by adsorbing heavy metals and organic pollutants, thus reducing their impact on plants.

Technical details

This Life Cycle Assessment (LCA) study evaluates the environmental impact of SoilPoint’s humic soil boosters produced from oxidized lignite brown coal in Kazakhstan and exported to the UK. It applies a cradle-to-gate approach, following ISO 14040/44 standards, considering the entire process from raw material extraction to product transportation and comparing the impacts of humics to conventional chemical fertilizers.

CARBON SEQUESTRATION

SoilPoint's Soil Booster enhances carbon sequestration both in the soil and above ground biomass, effectively reversing the trend of rising atmospheric greenhouse gases.

By adopting SoilPoint's innovative farm management practices, farmers can generate carbon credits while improving soil health and sustainability.
