Our results
We have tested our approach across 9,500+ hectares – from broadacre cropping, to grazing, to plantation forestry, to environmental plantings – over nearly a decade.
The results have been compelling.
Snapshot of Tiverton Global’s achievements on its demonstration farms between 2020-2024 across grazing, cropping and horticulture assets. Please note that these results are site-specific and reflect the unique environmental and management conditions of the demonstration period; they should not be viewed as a guarantee of performance across all farming systems or timeframes.

Soil health
-
Across Tiverton Global’s operations, our soil monitoring is showing substantial, quantifiable improvements in soil health indicators since 2020. At Orana’s cropping operation, overall soil health scores have risen by 95%, based on a suite of biological and chemical soil metrics. Fungal biomass has increased by 308%, with protozoa biomass up 121%, indicating a strong resurgence of soil biology.
In Orana’s olive grove, mycorrhizal populations have expanded by 1,200%, contributing to a 21% uplift in overall soil‑health scores since 2020.

Across Orana’s 1,000 ha irrigated olive grove, measured soil organic carbon has increased by 88.97% between 2020 and 2024, equating to 82,652 t CO₂‑e sequestered.
Orana’s 2,818 ha of assessed cropping land, measured soil organic carbon has increased by 41% between 2018 and 2024, equating to 35,823 t CO₂‑e sequestered over this period.

Recovery of soil health through our program is clearly linked to stronger crop establishment, development and resilience:
At the Orana olive grove (1,000ha), after just three years, yields are in the top 5% of producers, with fruit 25% heavier and oil production 36% higher than the world average
At Ardgartan Farm (4,100ha), prime lamb carcass weights have risen by 33%
At Peringeri in WA, after only one year of CircleAG application, grain crops out‑performed both conventional practice and a leading competitor liquid biofertiliser by 34%.
Across our cropping operations, root systems are up to three times greater after four years of CircleAG application, supporting better access to water and nutrients and improved stress tolerance.
Farm production
-
By improving our soil health we’ve transformed the soil into a massive natural sponge. Orana’s 1,000-hectare olive grove now holds an extra 83 million litres of water – about 83,000 litres per hectare stored right where the roots need it.
This moisture is ‘banked’, enabling a living ecosystem that supercharges soil microbes, captures every drop of early rain to prevent erosion, and ensures crops have a steady supply of nutrients between rainfall events.
By restoring the soil’s natural ability to hold water, we are improving landscape resilience and driving increased yields and quality.
Drought resilience
-
CircleAG has been applied to new native forestry plantings and is demonstrating exceptional resilience and growth rates.
Across a 4-month period from planting, seedling survival rates are 44% higher compared to untreated baselines.
The addition of CircleAG microorganisms and plant protective compounds (PPCs) drove a 70% increase in tree height (an additional 17.2cm) compared to the control group within the same period.
Average mean tree diameter has risen from 2.7cm in the control to 3.9 cm under our specialised management (a 45% increase).
Stronger early growth allows seedlings to outcompete weeds and resist environmental stressors more effectively, significantly reducing the management costs typically required during the first three years of growth.
Plantation yields
-
Recovering soil health through the Tiverton Global ArgriSystem is also improving the nutritional value of the food we grow.
For example, at Orana olive grove, olives have 65% higher antioxidants compared with other Extra Virgin Olive Oils in the Australian market; lamb recorded significantly higher Omega-3 levels compared with feedlot and conventional grazing systems; and our oat crop recorded a test weight (58 kg/hl) significantly above the current Grain Trade Australia milling oat receival minimum (51 kg/hl), indicating strong grain density and quality. This has direct flow-on benefits for human health and wellbeing.
Tiverton Global has partnered with Deakin Distinguished Professor Felice Jacka OAM, Founder and Director of the Food and Mood Centre, to form the Tiverton AgriSystem Science Advisory Board. This Board comprises a globally recognised team that will help advance research verifying links between soil health, food nutrient density, and human health and wellbeing.
Food nutrient density
Bringing back nature
Our nutritional agriculture model goes beyond production to drive active landscape recovery. Through our partnership with Odonata Foundation, we access specialist consultation services to guide our conservation strategy. This allows us to reinstate ecosystem services and resilience essential for long term productivity - including by reintroducing threatened species into target landscapes.
Measuring what matters
Our impact is underpinned by verifiable, science-led data.
We use a suite of tools – including high-precision remote sensing and digital twin modelling, Federally approved soil carbon measurement, and advanced lab testing such as Haney and PLFA – to ensure our results are accurate and independently reported.
By applying rigorous measurement to our natural capital, we ensure the integrity of our results, provide our investors with transparent view of their impact, and ultimately support our bottom line.
