About this episode
Welcome back to Hydroponics Daily! In this episode, Dr. Russell Sharp unveils a hidden dimension of plant nutrition that's transforming the way we view air pollution. While air pollution is often discussed in terms of its negative impact on health and climate, Dr. Sharp dives into the lesser-known ability of plants to absorb airborne pollutants, such as nitrogen oxides, ammonia, and sulfur compounds, directly through their leaves. Discover how these pollutants are converted into essential nutrients and how this phenomenon is particularly useful for urban and industrial farming areas. Dr. Sharp explores the historical context, detailing how some plants even thrive with pollution-derived nutrients, challenging the conventional reliance on soil-based fertilizers. Join us as we unpack the complexities of air pollution as a nutrient source, its benefits, and potential risks. From innovative urban farming insights to practical approaches on managing these inputs in hydroponic systems, this episode offers an enlightening perspective for both urban farmers and hydroponics enthusiasts alike. https://eutrema.co.uk/shop/fertiliser/sulphur-fertiliser-65-so3/
