As Australian growers look to improve nutrient efficiency, crop performance, and soil biology under increasingly variable conditions, biostimulants continue to play a growing role in modern farming systems. Terragen’s Great Land Plus® (GLP) has been independently evaluated and commercially demonstrated across a range of crops and regions, providing growers with practical insights into how microbial biostimulants perform under real-world conditions. The Great Land Plus® Research Update 2026 brings together the latest findings from independent compatibility testing and large-scale commercial trials conducted across Australia. Independent Compatibility: What Growers Need to Know An independent study assessed the compatibility of Great Land Plus® with Roundup Ready® herbicide programs, focusing on microbial survival and practical spray operations. The research confirmed that when GLP is mixed and applied within a 2–6 hour window, approximately 64–68% of viable microbes are retained, supporting its use in same-day spray programs. However, holding tank mixes overnight significantly reduced [...]

As Australian beef producers continue to search for ways to improve feedlot performance, average daily gain, and animal health without increasing feed costs, on-farm trials remain one of the most reliable decision-making tools. A recent client-led feedlot trial conducted by a leading Western Australian beef producer evaluated the real-world impact of Terragen’s Probiotic for Ruminants when included in a standard feedlot ration. Unlike controlled research studies, this trial was designed to reflect commercial feedlot conditions, providing practical insights for producers considering rumen probiotics to improve cattle performance, health, and efficiency. Trial Objective: Measuring Feedlot Performance and Animal Health The objective of the WA feedlot trial was to assess the impact of Probiotic for Ruminants on key commercial performance indicators, including: Average daily weight gain (ADG / OADG) Animal health and sick treatment rates Drafting timelines and days on feed Final liveweight outcomes Two feedlot pens were monitored side-by-side, with [...]

Tank-mixing inputs is a standard practice across Australian farming systems — delivering efficiency, flexibility and cost savings. However, when biological products are involved, understanding compatibility and timing is critical to achieving the desired outcome. New laboratory research has assessed the compatibility of Great Land Plus® (GLP) when tank-mixed with Roundup Ready® Herbicide with Plant Shield®, providing growers and agronomists with clear, evidence-based guidance for use in real-world spray programs. Why Compatibility Matters Unlike conventional chemistry, biological products contain living microorganisms that can be affected by water quality, tank-mix partners and the length of time a spray solution is held before application. As Graham Page, Lead for Plant Biostimulants at Terragen explains: “Biologicals can absolutely be used alongside herbicides — but they need to be handled with intent. Time, order of mixing and spray discipline all play a role in protecting microbial viability.” What Was Tested The study examined GLP performance [...]

The Hidden Workforce Beneath Our Feet Soil is not just dirt; it’s a dynamic ecosystem. Billions of microorganisms—bacteria, fungi, protozoa—work together to cycle nutrients, build soil structure, and protect plants from disease. These microbes: Break down organic matter, releasing essential nutrients like nitrogen and phosphorus. Improve soil aggregation, enhancing water infiltration and reducing erosion. Form symbiotic relationships with roots, increasing nutrient uptake and plant resilience. When these functions thrive, crops grow stronger, inputs like synthetic fertilizers and pesticides decrease, and the farm becomes more resilient to climate extremes. Ecosystem Function and Financial Stability Supporting positive ecosystem functions isn’t just good for the environment—it’s good for business. Healthy soils reduce dependency on costly inputs, improve water efficiency, and stabilise yields over time. This translates into: Lowering input costs through natural nutrient cycling. Higher productivity from improved root health and soil structure. Risk mitigation against droughts and floods thanks to better [...]

Terragen’s ongoing research and development program has delivered exciting results from recent trials across a range of crops, confirming the effectiveness of Great Land Plus® (GLP) in improving plant growth, nutrient efficiency, and crop performance. Trial Results Across Multiple Crops Trials conducted on maize, tomato, ryegrass, canola, and lentils have demonstrated significant benefits for both plant growth and sustainability outcomes. Maize Trials (QLD & NSW) – Up to 30% increase in shoot weight and 35% increase in root weight, with medium and low doses proving most effective. Tomato Trials (Laboratory & Soil) – Growth benefits observed in both sterile agar and soil trials, confirming GLP works directly on plants as well as in the soil. Lentil Trial (South Australia) – Conducted in partnership with Elders Rural Services, this opportunistic trial on a late-sown lentil crop confirmed GLP’s role in supporting crop establishment and vigour. Applications [...]
