Case studies

Wind Farm Project

Central NSW

The challenge

To revegetate previously polymer-treated steep batters at a site in the Mudgee area of Central NSW under sub-tropical storm conditions. 

Our brief was to provide a long-term, self-sustaining solution that required minimal maintenance. 

The solution

Our team applied EnviroMatrix (ECM) Biotic Growth Amendment at a rate of 10 Tonnes per hectare to encourage strong, swift vegetation growth. 

Included in the EnviroMatrix ECM slurry was our EnviroBond long-term storm guard polymer, which was applied at a rate of 400 Litres per hectare. EnviroBond was used under dryland conditions without any soil seed bed preparation, which wasn’t ideal.  

The ECM Biotic Growth Amendment is an all in one bag product that includes soil conditioners and microbial coated mineral-based fertiliser with trace elements. The fertiliser is non-water soluble, eliminating the risk of nutrients contaminating the surrounding environment. 

This combination of products was selected to provide immediate and longer term erosion control that would hold the EnviroMatrix onto the slope, allowing for effective vegetation establishment and a long-term self sustaining outcome.

The results

Nine months after the application of ECM, a well established vegetative cover, including native plant species, had developed under natural rainfall conditions and without any erosion. The dryland non-watering program used on this site is designed to protect seeds from insects and unfavourable climatic conditions until germination and plant establishment occurs.
