Unlocking Plant Potential: The Science of Carbon and Natural Fertilizers with Nik Nikolayev

What if carbon is one of the most overlooked inputs in plant nutrition? In this episode of the Bioactive Podcast, Dr. Riley Kirk sits down with Nik Nikolayev, CEO of Rooted Leaf Agritech, to explore the science of carbon-based fertilizers, plant nutrition, biostimulants, organic acids, and the chemistry behind plant growth, yield, and quality. Nik breaks down how plants use carbon beyond simply taking up CO₂ from the atmosphere, and why forms of carbon such as acetate and citrate may provide important substrates that can enter plant metabolism. The conversation explores how carbon interacts with NPK nutrition, photosynthesis, energy allocation, nutrient uptake, and secondary metabolism, including the pathways involved in producing cannabinoids, terpenes, flavonoids, and sulfur-containing compounds. They also dive into natural fertilizers and plant-based biostimulants, including kelp, hibiscus, moringa, anthocyanins, humic and fulvic acids, and other botanical inputs. Nik explains the idea behind using medicinal plants and their chemistry in agriculture, how organic acids can interact with minerals, and why the form of a nutrient may matter as much as the nutrient itself. The conversation also explores the carbon economy of cannabis, trichome metabolism, terpene diversity, rare cannabinoids, sulfur chemistry, nutrient stress, and the challenges of testing compounds that occur at extremely low concentrations. Throughout the episode, Nik emphasizes the importance of connecting theoretical chemistry with practical growing results while acknowledging where the science is still developing.
