Research Scientist Sarah Rich Illuminates the Hidden World of Plant Roots.
Sarah Rich, an Agriculture and Food research scientist, is dedicated to understanding what happens beneath the soil. Her primary focus is on how plants grow and develop, particularly their roots. She investigates various factors, including genetics, planting conditions, and management practices, that influence plant growth.
Rich has a special interest in root systems and their crucial role in plant health. “Part of my passion for roots comes from how responsive they are,” she explains. “They can be difficult to study, but they’re truly fascinating.” She adds, “Given my interest in belowground processes, I often find myself digging holes and washing soil off roots more than you might expect.”
Addressing Drought Resilience
One of Rich’s key research areas is drought resilience and finding ways to mitigate the effects of drought in Australia. She notes that Australian farmers are facing significant challenges due to rapidly changing rainfall patterns. According to the Bureau of Meteorology, annual rainfall in some regions is already below average, and predictions indicate more frequent and severe droughts in the future.
Despite these challenges, Rich sees the changing climate as an opportunity for innovation. By studying how plants respond to environmental changes and examining farming systems, she aims to support Australian agriculture in adapting to new conditions. Her research includes assessing how soil moisture influences crop establishment, which is vital for successful growth, and exploring the impact of climate change on crop rainfall.
“Sometimes I focus on individual seeds or a plant’s root system, while other times I consider an entire crop in a yearly rotation,” Rich states. “Depending on the season, I conduct experiments in the glasshouse or visit field trials in grain-growing regions. I’m fortunate to balance hands-on research with the support of skilled technicians.”
Exploring Deep Sowing Techniques
Rich emphasizes the importance of creative problem-solving in modern science. She appreciates the diverse perspectives that her colleagues bring to the table. “Different viewpoints are crucial for addressing new scientific challenges,” she remarks. “Farmers, in particular, have a wealth of knowledge and are open to experimentation, providing valuable insights for research.”
The dynamic nature of her work means Rich often juggles various projects to secure funding, allowing for flexibility and new discoveries. Currently, she is investigating how deep sowing can provide farmers with more options, especially during dry periods. “I’m looking at when, where, and how often deep sowing can help seedlings establish and allow plant roots better access to soil moisture,” she explains. “By analyzing soil water and temperature, we are discovering how these factors influence growth and crop establishment with increased sowing depth.”
Finding Your Path
Reflecting on her career journey, Rich emphasizes the importance of following one’s passion. Before becoming an agricultural researcher, she worked as a theatre lighting electrician in the arts industry. “I believe that if you enjoy your work, you’re successful, no matter what it is,” she says. “Find an aspect of science that excites you and pursue it without worrying about conventional measures of success.”
Rich’s love for the arts continues to influence her scientific work. She admires artists like Diana Scherer, who creates textiles and sculptures from plant roots, and Heather Ackroyd and Dan Harvey, who grow grass under various light conditions to produce intricate portraits. “They explore light-induced chloroplast development in a much more creative way than I did during my PhD!” she adds.
Through her research, Sarah Rich is not only contributing to agricultural resilience but also inspiring others to find their unique paths in the world of science.
