The continuous trend of agricultural farm equipment getting bigger and heavier axle create concerns of soil compaction from excessive loading on wet and loose soil conditions, negatively impacting water infiltration, root development, and crop yield. Join Aaron and Mehari for a conversation on recent research, field measurements, and how this translates to management practices in the field.

Extension specialists working to improve soil, water quality, and wildlife habitat will address progress toward statewide conservation goals and efforts in a roundtable discussion format. The session will include highlights of new research and opportunities for farmers, landowners and professionals to get involved.

Ag Decision Maker has been providing farm management analysis and insight into many of the issues facing modern agriculture since 1996. The Ag Decision Maker website provides the resources and tools to help farmers make informed decisions when it comes to the economics of their farm business. Discover new resources and learn more about the surveys and publications you likely use already in your...

When was the last time Iowa had an 'average' weather year? As Iowa, and the Midwest, continue to experience more 'extreme' weather events this presentation will focus on managing soil moisture to increase the long-term resilience of your operation.

Drainage is important for agricultural production but delivers nitrate to downstream waters. This talk will discuss how we can balance drainage and downstream nitrate loss and how we might be able to use the emerging practice of drainage water recycling to reduce nutrient loss and enhance crop production

Understanding soil moisture

Streambank erosion is a complex, and fascinating, process driven by a range of on-site and watershed factors. We'll explore causes, impacts, and realistic control - the latter being achievable through understanding of watershed drivers, as well as on-site management practices.

Farmers and crop consultants continue asking many questions about fertilization with micronutrients in Iowa given an abundant supply of many products for application to the foliage or the soil. The presentation will discuss research results about the value of soil and plant tissue testing for making rational decisions.

There is no single best P or K nutrient management practices (BMPs). Farmers and crop consultants can use different soil-test interpretations and fertilizer management practices based on different combinations of agronomic, economic, and water quality considerations. The presentation will discuss the potential impacts of P and K management practices recommended by ISU and others commonly used i...

The Iowa Nitrogen Initiative (INI) is a public-private partnership that works with directly with Iowa farmers to conduct nitrogen rate research on their farm fields. In 2023, 270 trials were conducted, a 400% increase from the pilot year in 2022. In this presentation, INI researchers and staff will give a short overview of the project and present yield response data from the 2023 trials, ending...

Plant essential oils are a type of biopesticide that has shown effectiveness against several plant pathogens and pests. Our goal is to develop seed treatments that are effective against soilborne pathogens of soybeans. We will present our research ingscreen essential oils for activity against the SDS, white mold, charcola rot and Pythium root rot pathogens

Larger and more productive dry fertilizer applicators increase the risk for non-even fertilizer placement. Tips and best practices will be covered to understand risk factors and ways to mitigate yield losses associated with dry fertilizer application.

Soil testing for potassium (K) is useful but is a less reliable diagnostic tool for phosphorus or lime requirements. The presentation will provide information to back Antonio's old saying "For K is better to err for higher tests and rates than to err for less than actually needed". A K deficiency can have more severe impacts on yield because it reduces the corn capacity to response to nitrogen ...
