Biostimulants are a growing trend in agriculture, with their use rapidly increasing worldwide, but there are still some questions about how they play a role in today's agriculture.   Yara's Marcio Wally, Biological Senior Manager based in Canada, explains that biologicals are complementary to traditional agricultural inputs like fertilizers and pesticides, enhancing crop nutrition and resilience to stress. Biostimulants can improve nutrient availability and uptake, as well as enhance plant aspects to resist crop stress. They do not replace nutrients or agrochemicals but rather enhance crop management. The types of biostimulants include non-microbials (seaweed extracts, humic substances, amino acids) and microbial biostimulants (beneficial bacteria and fungi). The choice of biostimulant depends on the specific needs of the crop and the desired outcome.

This video conversation discusses the influence of plant nutrition on root health. Dr. Rob Mikkelsen emphasizes the importance of roots and how they are often overlooked.

Rob highlights various research findings, including those from Dr. Dharma Pichay at Tennessee State University, demonstrating the negative effects of ammonium on a range of crops such as almonds, apricots, tobacco, strawberries, and tomatoes. He emphasizes the goal of Yara to provide optimal crop nutrition through their nitrate-based fertilizers, ensuring plants reach their full potential. Tune in to learn more about the significance of nitrate nutrition and how it can enhance crop performance.

In this episode, Dr. Rob Mikkelsen  teaches us about the fascinating and often overlooked world of root health and its crucial role in plant nutrition. He begins by posing a thought-provoking question: Do nutrients influence roots, or do roots influence nutrients? The answer, as Rob explains, is a complex interplay of both. The Hidden Half of Agriculture: Rob emphasizes the importance of roots, which are frequently overlooked despite their critical role in plant health. He encourages agronomists and farmers to always carry a shovel to inspect root health regularly. Complex Structure of Roots: The episode highlights the significance of root hairs in water and nutrient uptake. Rob explains how calcium is absorbed only at the root tips, underscoring the need for healthy roots to continually explore new soil zones. Historical Perspective on Nutrient Uptake: Rob shares an old illustration that depicts nutrient uptake as a train system, transporting nutrients to the “factories” in the leaves. This analogy helps explain the complexity of nutrient assimilation processes. Influences on Root Health: The podcast discusses several factors that affect root health, including: Soil Acidity: High soil acidity can stunt root growth due to toxic soluble aluminum, but this can be remedied with proper limestone applications. Soil Salinity: Excess salt can cause water stress and reduce plant performance. Soil Compaction: Compact soil can hinder root penetration, affecting water and nutrient uptake. The Role of the Rhizosphere: Rob introduces the rhizosphere, the narrow zone surrounding roots, rich in biological activity. He highlights its importance in nutrient uptake and overall plant health.
