Guilfoyle Carbon project
The Guilfoyle Carbon Project, located in Birchip, Victoria, has been issued 382 ACCUs under the ACCU Scheme, the first credits banked on the Kemp family's Mallee cropping country.
Landholders Colin and Nathan Kemp farm heavy Mallee clay and, with support from AgriProve and LawrieCo, spent the past eight years reworking their whole nutrition program, combining synthetic and biological fertilisers to build soil health and cut input costs.
Farm Profile
Enterprise: Wheat and barley cropping on heavy Mallee clay
Rainfall: 160mm in-crop rain in 2025, one of the driest seasons on record
Soil Types: Historically compacted "tennis-court clay," now friable to 40mm when dry
Cropping Rotation: Wheat, Barley
Previous Practice: Broadcasting 200 to 300kg per hectare of urea
The project has generated
Project Highlights:
One of the largest soil carbon credit issuances in Victoria to date
10,548 Australian Carbon Credit Units (ACCUs) issued under the ACCU Scheme
Average increase of 7.1 tC/ha in treated areas using biology-led fertiliser strategy

Results
With AgriProve as the project aggregator, the Barwick Carbon Project demonstrates how meaningful change can happen in a short timeframe. Between mid-2022 and early 2024, Geoff Vivian transitioned to a biology-led fertiliser program, improving nutrient efficiency, soil structure, and overall system resilience, all while maintaining crop yields.
Satellite imagery in late 2023 highlighted strong performance in treated areas, and the required soil sampling and analysis confirmed the gains. With no measurable improvement in the untreated control zone, the results reinforce how targeted practice changes can turn soil health into tangible on-farm outcomes.
2024 GROWING SEASON: Comprehensive Program of Soil Carbon Building Fertilisers Geoff has expanded his carbon building program to include more LawrieCo inputs, with no loss of yield and a continual improvment in soil health.
Seed Treatment: SureCrop – biostimulants, nutrients, and biology
Granular Fertiliser: BioMAX Humate Prill with MAP
Foliar Nutrition: NutriMAX PhosCal, BioMAX Boost, HumiPLEX ZMC
Ag-Chem Sprays: Buffered with BioMAX F75
Geoff Vivian: “With LawrieCo's (and AgriProve’s) support, we started our carbon farming projects to address underperforming soils and below-average yields. Our goal is to improve soil biology, boost nutrient efficiency, and build land value by integrating LawrieCo products.”
WHY AGRIPROVE
AgriProve uses data driven tools and unique financing mechanisms to make regenerative grazing accessible and profitable for farmers. Partnering with landholders and industry leaders to mutually benefit from carbon project success. Our unique ACCU success fee model removes the risk and creates a true partnership for the entirety of the project.
Utilising AgriProve’s innovative, digitally enabled Soil Organic Carbon (SOC) model project partners benefit from the expedited soil sampling and carbon crediting process.
““Long-term, we aim to enhance soil fertility through smarter, biology-led farming, while generating a new revenue stream.”
