17. What's in a Soil Test? Getting the Answers with John Breker Pt. 1 Sep 18, 2024

Show notes

Get the download on soil tests and what they actually mean in our latest episode of Ag Geek Speak featuring AGVISE Laboratories' John Breker. We dive into the world of soil testing methods, breaking down the pros and cons of phosphorus tests like Olsen and Bray, and the "new" Mehlich-3 method. Discover why Olsen is often preferred in the Great Plains and how the Mehlich-3 method, despite its promise as a universal extraction tool, might over-extract in calcareous soils. The discussion highlights the importance of selecting the right soil test for accurate nutrient analysis, a crucial step for any farmer or agronomist looking to optimize crop yields.
Managing soil pH and tackling nutrient deficiencies, especially iron deficiency chlorosis in soybeans, can be challenging. John provides an in-depth look at the role of calcium carbonate and the necessity of specific soil tests to combat IDC effectively. We also explore concepts like reserve acidity and cation exchange capacity, explaining how soil texture influences these factors and the difference between water pH and buffer pH. If you're keen on practical strategies for managing soil fertility and improving crop yields, this episode is a treasure trove of knowledge. Tune in and equip yourself with actionable insights from one of the field's leading experts!

16.5 Tiny Bytes: Choosing the Right Soil Phosphorus Test: Olsen, Bray 1, and Mehlich-3 Methods Unveiled Sep 11, 2024

Show notes

In this episode, we unpack the intricacies of soil test phosphorus methods and reveal why not all tests are created equal. We break down the specifics of the Bray 1, Olsen, and Mehlich-3 methods, explaining how they each cater to different soil conditions. Whether you're dealing with acidic, neutral, or calcareous soils, understanding the right test for your soil type can make a difference in your phosphorus fertilizer plan.
Ever wondered why a single phosphorus test doesn't fit all fields? We highlight the Olsen method's superiority in the northern Great Plains given the region's calcareous soils and weigh the advantages and limitations of the versatile Mehlich-3 method. The episode also delves into the concept of calibration and the essential role of university-led yield trials in developing precise fertilizer guidelines.

Iron deficiency chlorosis (IDC) in soybeans can be a formidable challenge. What if you could manage it with precision agriculture? Join us for an enlightening conversation with Professor Emeritus Dr. R. Jay Goos, a leading authority in the topic, as we discuss how farmers can pinpoint and treat IDC in their fields. Dr. Goos delves into the intricate world of breeding IDC-resistant soybean varieties and discusses the vital role of resources like NDSU's IDC variety trials (https://vt.ag.ndsu.edu/view/6750).
What are some ways that IDC can be managed with precision agriculture methods? Dr. Goos, Sarah, and Jodi discuss. Knowing previous crop history and collecting satellite imagery from soybean years can be put together to create "IDC" management zones that can be targeted for management. These IDC maps can help direct the use of iron EDDHA fertilizers, variable seeding rates, and variable fertilizer rates to manage soybean IDC.
Ever wonder why old herbicides are making a comeback? Dr. Goose draws fascinating parallels between agricultural trends and fashion cycles, emphasizing the importance of increasing soybean density to combat IDC. From soil testing techniques to the potential of precision agriculture, we cover it all. Finally, we'll take a closer look at advancements in North Dakota agriculture, from managing salt-affected soils to the pivotal role of research extension centers and the North Dakota State Board of Agriculture Research and Education in driving agricultural innovation.
