Dr Bridget Watson will deliver the ESI Challenge of the Month talk "Growing plants sustainably: harnessing the power of the soil microbiome" on Monday 2 June 1 - 2pm in the ESI Trevithick Room.

Growing sufficient food to feed the world is a huge task, especially when faced with a growing population and the unpredictability that comes with climate change. However, many current agricultural practices can be damaging to the environment, as intensive farming can deplete soils, reducing soil fertility. In addition, the use of synthetic fertilisers and pesticides can pollute water ways. Going forward, agricultural production must become more sustainable to ensure that the land can continue to provide for future generations. Addressing this complex challenge will require a multifaceted approach, but focusing on the microorganisms in the soil and harnessing their ability to support plant growth will be a key component.

My research focuses on soil microbes that naturally support plant health and aims to bridge gaps in our understanding of plant-microbe interactions so we can effectively use microbes as tools for sustainable agriculture. More specifically, I study beneficial soil bacteria from the Azospirillum genus, alongside wheat and related plants, as a model system to understand the mechanisms underpinning how bacteria promote plant growth. Further, my work examines how bacteria evolve and adapt in the dynamic soil environment, plus how plant-bacteria interactions are influenced by various factors in the complex soil environment.
