Queensland, Australia, 27th July, 2026 - Terragen has announced the appointment of respected agribusiness and agronomy leader Maree Crawford as Manager, Innovation and Adoption, strengthening the company’s national capability as interest in biological solutions continues to grow across Australian agriculture. Maree joins Terragen with extensive experience across agronomy, fertiliser innovation, crop and livestock production, and the commercial adoption of emerging agricultural technologies. In the newly created role, Maree will work with producers, advisers, retailers and industry partners to help translate Terragen’s microbial science and product development into practical, on-farm application. Her appointment also marks an important milestone for Terragen’s national growth, with Maree becoming the company’s first dedicated on-ground representative in Queensland. Terragen’s team now spans every state of Australia. Terragen Chief Executive Officer Richard Norton said Maree’s appointment reflects the company’s focus on supporting producers with evidence-led biological products that can be integrated into real farming systems. “Biological [...]

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 [...]
