Enhancing Ecosystem Resilience: A Soil Health Study Across Gisborne

Jacopo orazi





The collaboration between Radice Soil Solutions and Ecoworks represents a shared commitment to understanding and restoring soil health across diverse ecosystems in Gisborne. From farmland to wetlands, and restoration areas to untouched native forests, this project aims to set a new benchmark for sustainable soil management.


The Approach: Understanding Ecosystem Dynamics


A robust methodology was central to this project, involving:


  • Nutrient Analysis: To measure essential soil nutrients and their availability to plants.

  • Sap Testing: Providing insight into the nutrients plants are absorbing, bridging the gap between soil content and plant health.

  • Microbial Analysis: Examining the diversity and functionality of soil organisms, with a focus on fungi, bacteria, and soil predators.

  • Visual Soil Assessment: Evaluating physical characteristics like structure, porosity, and compaction, alongside indicators like earthworm counts.


By integrating these methods, we gained a full understanding of soil and plant interactions, including how biological activity supports nutrient cycling and ecosystem resilience.


Important Findings


Despite following best practices in restoration areas, fungal populations (both in diversity and density) have not recovered to native forest levels. Undisturbed native forests showed 60 times more fungal biomass than the restoration areas, emphasizing the gap in biological recovery.

This discrepancy highlights the critical role of fungi, especially mycorrhizal fungi, in supporting native species. These fungi form symbiotic relationships with plants, improving nutrient uptake and resilience. To address this, we are now exploring methods to reintroduce fungal populations into restoration areas, with a focus on boosting the survival rates of native plant species.


A Path Forward

This study underscores the importance of soil biodiversity, particularly fungal communities, in building resilient ecosystems. By leveraging the insights from native forests as benchmarks, we are developing strategies to restore biological balance and enhance the success of ecological restoration projects.
