Soil Carbon Capacity Building

The Soil CRC’s free Soil Carbon Capacity Building webinar series helps NSW farmers, landholders, and advisors understand and manage soil carbon on-farm.

Across seven webinars — six already delivered and available to view — the series covers soil data access, interpretation, and region-specific practices for improving soil carbon.

Evaluating novel approaches for drought resilience through capitalising on an established network of long-term trials

This project uses long-term trial sites and advanced crop modelling to compare innovative and conventional soil and farm management practices, assessing their impact on soil water, productivity, and resilience under current and future climate scenarios.

Its goal is to build drought-resilient farming systems across Australia by identifying practices that strengthen productivity, profitability, and recovery in dryland, grazing, and mixed farming environments.

Organic-Based N Fertilisers

This project is testing three new slow-release organic-based nitrogen fertilisers—made from peanut shell biochar, cow manure, and green waste compost—to determine whether they can improve nitrogen use efficiency, crop performance, and soil health compared with conventional urea.

Trials in NSW, VIC, and QLD will measure crop uptake, yield, and soil function across multiple farming systems to assess their potential as more sustainable, cost-effective fertiliser options.

Building resilient soils and enhancing carbon stocks in cropping systems through plant diversity

This project is examining how greater plant diversity—through cover crops, intercropping and varied crop rotations—can improve soil resilience, boost carbon dynamics and maintain or lift productivity in Australian cropping systems.

Using long-term trials at CWFS and partner sites, researchers are measuring impacts on soil carbon, microbial communities, soil structure and system performance to identify practical agronomic strategies that build healthier, more resilient soils.

Rhizobial Carriers

This project is developing and testing new organic and inorganic carriers for rhizobial inoculants to improve rhizobia survival, nitrogen fixation and crop performance, addressing the limitations of peat-based carriers and heat- and moisture-related losses.

By evaluating biochars, biopolymers and other low-cost materials across diverse regions and soils, the research aims to deliver practical, cost-effective alternatives that boost legume productivity and soil health in Australian farming systems.

Soil water storage

This project is measuring how different soil management and amelioration strategies influence soil water infiltration, storage and crop use, while also assessing water competition in mixed-species cover crops.

Soil Microbial Indicators

This project is investigating how plant diversity in rotations, intercropping and cover crops influences soil microbial processes, nutrient cycling and overall soil function across different farming systems and environments.

By testing a wide range of soil biology indicators at multiple sites and seasons, the research aims to identify which microbial measures are most useful for guiding on-farm decisions that improve productivity, soil health and resilience to stresses like drought.

Risk/reward of new farming practices

This project is creating a reporting tool that helps farmers better assess the full risk–reward profile of new farming practices by incorporating financial, environmental, social and governance factors rather than relying solely on traditional gross-margin analysis.

Unlock Soil Nutrients

This project is assessing how organic amendments such as manures, composts and biosolids can unlock bound soil nutrients, improve nutrient-use efficiency and enhance fertility across different soils and cropping systems.

By analysing nutrient forms, testing innovative application methods and evaluating plant uptake and soil responses, the research aims to provide practical, sustainable alternatives that reduce reliance on conventional fertiliser resources.

Rhizosphere modification

This project is investigating how increasing plant diversity through rotations, cover crops and perennial legumes can reshape rhizosphere processes to improve soil function, moisture dynamics, crop performance and farm profitability across different farming systems.

Knowledge Sharing

This project is developing and testing locally tailored knowledge-sharing strategies to boost landholder engagement in soil-health practices, helping grower groups use more effective extension methods—from digital tools to field days—to drive adoption of best-practice soil management.
