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. They explain the impact of nitrogen, phosphorus, potassium, calcium, and micronutrients on root growth and health. He provides examples and visuals to illustrate the effects of nutrient deficiencies on roots. The conversation concludes by highlighting the significance of a balanced supply of nutrients for overall plant health and the importance of discussing the source of nutrients in promoting root health. Takeaways Roots are often overlooked but play a crucial role in plant health. Nitrogen promotes the development of a dense and extensive root system. Phosphorus influences root architecture and stimulates associations with mycorrhizal fungi. Potassium affects overall plant growth and water relations. Calcium is involved in many aspects of root health and triggers hormone production for root growth. Micronutrients are important for root growth and health. A balanced supply of nutrients is essential for root health and overall plant health.

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.Subscribe to our channel to stay updated on future episodes where we continue exploring the fascinating world of plant nutrition and its impact on crop health.

This episode of the Yara Crop Nutrition Podcast focuses on the vital role of potassium in citrus production and how it can boost yields. Potassium is crucial for water, nutrient, and carbohydrate movement in plants, enhancing leaf size, tree vigor, and overall health. It plays a major role in crop yield and fruit quality in citrus crops. Citrus trees take up more potassium than nitrogen, making it a critical nutrient. The right source of potassium depends on soil type and timing of application. Frequent applications in smaller doses are recommended for better nutrient uptake. Potassium deficiency can lead to hindered growth and smaller, lower-quality fruit. Yara Sales Agronomist, Vanessa Dominguez, joins us to help explain this agronomic golden nugget.

This is the first in a series of episodes focused on the five incubator farms that Yara is managing in North America. Launched in 2019, the Yara Incubator Farms Network is not just a series of farms; it's a visionary project connecting the dots between farming practices and the global food chain. With over 600 acres across North America, these farms serve as a living laboratory where cutting-edge research in soil fertility and crop nutrient management is conducted. This isn't just about increasing yields; it's about revolutionizing how we approach food production in harmony with the environment.
At the core of this initiative is the commitment to a triple bottom line: achieving climate neutrality, fostering sustainable farming practices, and enhancing Prosperity—all while supporting the UN Sustainable Development Goals. Each farm within this network exemplifies Yara's dedication to these principles.
In this episode, we zoom in on a key player within this network—the Soil Health Incubator Farm in Auburn, Alabama. Situated within the EV Smith Research Station in collaboration with Auburn University, this 80-acre site serves as a prime example of how innovative farming practices can profoundly impact soil health and crop productivity.
Curt Knight, a Soil Health Agronomist at Yara, brings a wealth of knowledge with his Masters in Agronomy and soil science. Curt will shed light on the dynamic approaches being employed at the Auburn Incubator Farm to not only enhance soil health but also ensure profitable returns for farmers.

How important is the thin layer of crust on earth that we call soil? Dr. Rob Mikkelsen, Yara North America's Director of Agronomy, and soil science expert Professor John Havlin help us understand. Dr. Havlin's work has not only revolutionized grape cultivation in North Carolina but also advanced sustainable farming practices worldwide.
In this episode, we discuss the evolution of soil fertility practices, the impact of nutrient management on crop quality, and the significance of long-term agricultural trials. We'll also delve into Professor Havlin's intriguing research on wine grapes and how soil health drives the growing wine industry in North Carolina.
Nutrient management can become an opportunity for environmental stewardship.
Some Takeaways:
Soil science is crucial for sustainable agriculture and the future of food production. Nutrient management and long-term trials play a significant role in improving farming practices. The book 'Soil Fertility and Fertilizer' has evolved over the years to address changing agricultural practices and environmental concerns. There is a need for more young people to pursue careers in soil science and agriculture. Teaching quantitative skills in soil science is a challenge but essential for understanding the science behind soil health and fertility. The work with wine grapes in North Carolina has been the most exciting and rewarding for John Havlin. Nutrient management, particularly nitrogen application, plays a crucial role in improving the quality of wine grapes. Soil health and fertility are essential for successful grape growing. The grape industry in North Carolina has grown significantly in the past few decades.Dr. Havlin holds the position of professor and extension specialist in Crop & Soil Sciences at North Carolina State University. He has also served as the past president of the Soil Science Society of America. Dedicated to raising awareness about soil's crucial role, Dr. Havlin's efforts have contributed to the establishment of the House of Representatives Soils Caucus and a $4 million educational exhibit at the Smithsonian, which opened in 2008. This exhibit aims to educate the museum’s six million annual visitors on how soil is fundamentally connected to human health, environmental sustainability, and planetary well-being.
