About us
Since 1998, LawrieCo has been helping farmers and agronomists across Australia improve soil health and farm productivity through a smart fusion of biology and nutrition.
We design and manufacture a complete range of fertilisers, biostimulants, soil conditioners and seed treatments that work alongside conventional systems to enhance nutrient efficiency, plant resilience, and soil carbon. Backed by science and developed in Australia, our solutions deliver proven results in broadacre cropping, pasture, dairy, horticulture, viticulture, and turf.
We partner with resellers, agronomists and landholders to tailor programs that suit local conditions, production goals and sustainability outcomes. Every product we offer supports the LawrieCo Soil Carbon Regeneration System—a practical pathway to restore soil function and reward growers for building soil organic carbon.
Our mission is simple: to help growers get more from every hectare—more yield, more quality, and more long-term resilience—starting with the soil.
Area Managers
Rodney Capon - VIC, NSW & WA
Carbon & Biological Agronomy Specialist
0409 822 011 Rodney began his career as a landscape gardener in Adelaide before relocating to the Sunraysia region of Northern Victoria and Southern New South Wales in the late 1990s. There, he contributed to large-scale horticultural developments with a strong focus on improving soil structure, fertility, and long-term productivity. Throughout this period, Rodney was involved in the importation and trial of humate-based and biological soil conditioners—laying the groundwork for a deep and practical understanding of soil health. His early recognition of the value of soil carbon building positioned him ahead of the curve in biological farming. He later transitioned into the nursery industry, where he expanded his knowledge of carbon dynamics and microbial interactions in soil systems. In the mid-2000s, Rodney took over management of a large dryland cropping and grazing enterprise, incorporating irrigated and horticultural zones. It was here that he applied and refined regenerative practices using humates and biological inoculants—achieving outstanding results in both plant performance and soil organic carbon gains. Now a key member of the LawrieCo team, Rodney brings decades of real-world experience to support growers in building healthier soils, improving input efficiency, and generating long-term carbon outcomes.
Harry Clarke - SA
Projects & Carbon Development Agronomist
0481 385 281 Born and raised in Adelaide, Harry brings a strong technical background and passion for innovation in agriculture. While studying Agricultural Science at university, he developed a keen interest in agronomy and agtech, specialising in these fields in his final year. After graduating, Harry worked in the Precision Agriculture sector, with a focus on mapping software, guidance systems, and the practical integration of technology into farming operations. His work helped growers better understand and adopt precision tools to enhance farm performance and decision-making. At LawrieCo, Harry plays a key role in the company’s soil carbon project delivery, working closely with growers to help them build long-term value through improved soil health and carbon outcomes. He is also responsible for managing field trials, contributing to ongoing product development and validation to maximise grower benefit. Harry is passionate about supporting farmers to make data-driven, regenerative choices that deliver both agronomic and economic returns.
Sam Peters - SA
Area Manager and Agronomist
0498 346 212 Sam comes from a fifth-generation mixed cropping and sheep farm in the Mid North, where he developed a deep understanding of broadacre farming. As a mature-aged graduate with a degree in Agriculture, he has worked to bridge the gap between scientific research and practical on-farm operations. His passion for soil health and biology stems from firsthand experience regenerating unproductive, degraded soils on his family farm. Seeing the positive agronomic impacts of improved soil carbon levels, Sam is eager to assist and collaborate with likeminded farmers. With the first issuance of carbon credits in Australia's broadacre cropping sector and growing incentives to increase soil organic carbon, Sam is excited to help farmers leverage these opportunities for productivity and profitability. Beyond broadacre farming, Sam has managed and operated a wholesale plant nursery for three years and holds a degree in Human Nutrition and Dietetics, giving him a broad perspective on soil, plant, and human health.
