Natural soils: the foundation for biodiversity

Our Natural Areas are not just beautiful landscapes. They act as libraries for flora and fauna, making them essential for biodiversity conservation. Some of our natural areas also fulfil an important role in drinking water extraction.

But our nature is under threat from a number of factors:

  • Industrial activities: emissions of waste to air and water.
  • Intensive agricultural practices: Surplus of nutrients such as nitrogen and phosphorus, impact of plant protection products and dehydration due to intensive irrigation.
  • Traffic pressure: exhaust fumes and particulate matter.
  • Urbanisation: fragmentation of natural Habitats and disruption of natural water cycles.
  • Climate change: shifting climate zones requires faster adaptation of species, damage from extreme weather events.

These factors have a negative impact on the resilience of nature and hence the soil that forms the basis of these important ecosystems.

A healthy natural soil is crucial for the resilience of our natural areas

Natural soils are very diverse in terms of their microbiome - a collection of millions of microorganisms such as bacteria, archaea and fungi forming an ecological community. These microorganisms fulfil a wide range of crucial roles in the natural ecosystem. Healthy natural soils help with:

  • Carbon sequestration: They help store carbon in the soil, which contributes to climate change mitigation.
  • Water management: They influence soil structure, which is important for water retention and preventing flooding and drought.
  • Plant growth: They support plant growth by making nutrients available.
  • Disease protection: They form a natural defence mechanism against plant diseases.

Consequently, degradation of natural soils has major consequences.

Bioclear earth and Next Generation Sequencing

With Next Generation Sequencing (NGS), Bioclear earth maps the entire soil microbiome. This technology helps us understand how human activities affect soils and provides insights for remedial action. By interpreting NGS data and combining these with data on location, soil type, vegetation, hydrology and management, we can develop strategies to restore biodiversity and improve the health of natural soils.

Ecosystem restoration

The European Soil Health Law, to be rolled out in 2024, focuses on preventing soil degradation and restoring healthy soils by 2050. NGS data can help policymakers and nature managers formulate and monitor effective measures, for example to reduce loads of nutrients such as nitrogen and phosphate, improve carbon uptake and improve water quality.
