Spray drones are increasingly being evaluated by Iowa farmers as an additional tool for crop input application. When used appropriately, these systems can provide flexibility for timely applications, reduce field traffic, and improve access to areas that are difficult to reach with traditional ground equipment.

AMES, Iowa – The 2026 Crop Advantage Series will take place at 12 locations across the state Jan. 6–29. Each meeting will feature tailored topics selected based on local growing conditions and challenges, presented by Iowa State University Extension and Outreach specialists.

This year we are offering on-site registration for the Integrated Crop Management Conference! Join us on December 10-11 at the Meadows Events and Conference Center in Altoona, IA for two days jam-packed with networking, continuing education, and insight for 2026 and beyond. 

Highlights of this year’s event include:

Soil testing is an essential tool for managing phosphorus (P), potassium (K) and other nutrients. In Iowa and many states, the units reported in a soil test are expressed in parts per million (ppm) of the elements (not oxides P₂O₅ or K₂O, as in fertilizers) of dry or moist soil depending on the test. Different test methods can be used for a specific nutrient.

With low crop prices and increased fertilizer costs, farmers are wondering how best to allocate fertilizer dollars this fall. The following articles were posted in the fall of 2024, but all still apply to today’s situation and provide a list of best management practices (BMPs) in order of significance.
