Can Biologicals Improve Nitrogen Mineralisation?
Understanding the Role of Microbial Products in Modern Cropping Systems Nitrogen remains one of the most critical—and costly—inputs in modern agriculture. As pressure grows to improve nutrient efficiency, reduce losses, and lift system resilience, interest in biological products has accelerated. Among the most common questions growers and agronomists are asking is a deceptively simple one: Can biological products improve nitrogen mineralisation? The short answer is yes—but not in the way many expect. Understanding how and when biologicals contribute to nitrogen processes requires a clearer view of how mineralisation works, what limits it, and where microbial products realistically fit within a farming system. Nitrogen mineralisation is the biological process by which organic nitrogen—from soil organic matter, crop residues, manures, or composts—is converted into plant‑available inorganic forms, primarily ammonium and nitrate. This process is driven almost entirely by soil microorganisms. Crucially, mineralisation is governed by soil moisture and temperature, availability of[...]
Previously announced CSU feedlot trial now peer-reviewed: what the published TPR® results mean
Terragen is pleased to share that its previously announced Charles Sturt University feedlot trial has now been accepted for publication and is live in the Journal of Translational Animal Science. While this is not a new trial announcement, it is an important milestone: the results have now entered the peer-reviewed literature, giving producers, advisers and investors an additional level of confidence in how the findings can be assessed.Why this mattersIn agricultural biologicals, proof matters.Producers do not need more noise. They need confidence that a product has been tested properly, that results have been scrutinised externally, and that performance is being communicated with precision. That is what publication adds here.The CSU paper is based on the previously announced feedlot trial in 264 purebred Angus steers over 106 days on feed. It compared a control ration with no probiotic against liquid and dried direct-fed microbial treatments at different dose rates.What the published[...]

Great Land Plus® Research Update 2026: Proven Performance of a Microbial Biostimulant
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[...]
WA Beef Producer Feedlot Trial: Probiotic for Ruminants Performance Case Study
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[...]
Great Land Plus® Tank-Mix Compatibility: What Growers Need to Know
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[...]
Healthy soil isn’t just an environment goal – it’s a business strategy
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[...]

Australian Ag Biotech Steps Onto the Global Stage
Terragen launches first international feedlot trial for its Probiotic™ for Ruminants in Canada Terragen has taken an important step in expanding its global footprint, announcing the first international research trialof its Probiotic™ for Ruminants (TPR) — a live microbial supplement designed to support animal health and performance. The two-phase Canadian feedlot trial, conducted in partnership with the Agriculture and Agri-Food Canada (AAFC), the University of Calgary, and the Beef Cattle Research Council, will evaluate TPR’s effect on cattle growth performance, carcass quality, and gut-immune function under North American production conditions. AAFC’s Professor Trevor Alexander said the study aligns with their broader research focus on bovine respiratory disease (BRD) and animal health. “We’re excited to explore how probiotics influence gut and respiratory health in feedlot cattle,” he said. Phase one focuses on digestion, microbiota, and immunity across a 60-day period, while phase two extends to 300 days, assessing long-term[...]
