– Great Land Plus®
A microbial product designed to support soil biology, improve nutrient efficiency and enhance crop performance
Where GLP Fits
Great Land Plus® is a high-performance microbial biostimulant designed to activate the soil microbiome, stimulate root development, and maximize nutrient efficiency in broadacre, viticulture, and horticultural systems.
- Broadacre cropping
Horticulture
- Pasture systems
- Composting systems
Key Benefits
GLP isn’t just about feeding the plant; it’s about optimizing the environment around the roots – the rhizosphere. By introducing high-titer beneficial microbes, Great Land Plus® unlocks “locked-up” nutrients in the soil, making your fertilizer programs work harder.
- Supports nutrient cycling in soil
Improves fertiliser efficiency
Enhances plant growth and yield outcomes
Compatibility
One of the biggest barriers to biological use is compatibility. Our latest 2026 independent study confirms that GLP is highly stable in modern farming systems.
- Roundup Ready® Compatible: Confirmed 64–68% microbial retention when applied within a 2–6 hour window.
- Foliar & Soil Application: Effective via soil drench, foliar spray, or irrigation (fertigation).
- Shelf-Life: High microbial viability maintained throughout the season when stored correctly.
- How to Apply? GLP is designed to fit into your current schedule.
- Spray within 2–6 hours of mixing
- Avoid holding mixes overnight
- Add GLP last into tank
Nutrient Efficiency (ESG)
Reducing synthetic inputs doesn’t have to mean reducing yield. GLP allows growers to optimize their “Nutrient Use Efficiency” (NUE). By fostering a living soil, you reduce runoff and leaching, aligning your farm with global ESG standards and premium supply chain requirements.
- Key Results: +35% Root Weight: Increased root biomass for better drought resilience and nutrient scavenging.
- +30% Shoot Weight: Enhanced vegetative growth leading to higher yield potential.
- Optimised Nutrient Uptake: Improved efficiency of Nitrogen and Phosphorus applications.
Proven Outcomes
Broadacre
Great Land Plus® supports soil biology, nutrient cycling and crop establishment across broadacre systems. It is designed to complement existing fertiliser and spray programs while helping improve nutrient-use efficiency.
Trials recorded:
- Up to 44% greater root weight
- Up to 32% greater total plant weight
- Up to 40% higher lucerne hay yield
Results varied by trial, application and growing conditions.
Viticulture & Horticulture
Great Land Plus® supports root-zone biology, nutrient uptake and crop consistency in intensive and high-value growing systems. It can be applied through irrigation, soil drench or foliar programs.
Results included:
-
34% higher yield
- 9 t/ha increase in production
- 8% increase in soil organic carbon
Results relate to the specific systems and conditions assessed.
Cotton & Maize
Great Land Plus® supports root development, nutrient efficiency and crop performance in summer cropping systems. Replicated maize trials have shown significant yield improvements under the conditions tested.
Trials recorded:
- 12% increase in silage maize yield
- +8.8 t/ha compared with standard practice
- Up to 20% higher maize grain yield
Results are specific to the crop, application rate, trial design and environmental conditions assessed. View the relevant research for full details.
Composting Applications
Great Land Plus® supports microbial activity during composting, helping accelerate organic matter breakdown, retain nutrients and improve the quality of finished compost.
Helping to:
- Supports faster compost breakdown
- Helps retain nitrogen
- Assists odour management
- Improves the quality of finished compost

“We are consistently thinking of ways to push yield boundaries in our silage maize here at Ravensworth. Great Land Plus has displayed positive results this season, with yields up to 90 wet tonnes per hectare.”
“Since I’ve been using Great Land Plus, my pastures are really even and the health issues are a lot less.”
“Not only did the plants establish better, they grew faster and always had more flowers and fruit than the conventional treatment. This made the difference between a profit and breaking even.”
“We started using Great Land Plus to escape the cost of urea fertiliser. Since applying it to our paddocks, we have noticed clovers returning, along with a darker green and healthier colour through the pasture.”
“In a replicated maize trial, Great Land Plus-treated areas produced an average of 2.3 t/ha more grain than the untreated control, representing a 20% increase in yield under the trial conditions.”
