Variable Rate Technology
from UMN Extension Nutrient Management Podcast Hosted by University of Minnesota Extension
In this episode of the Nutrient Management Podcast, we’re talking about variable rate technology. What are some reasons that farmers might want to use variable-rate fertilizer instead of applying a single rate? Is there a difference between variable rating, different nutrient types? What are the technologies that are used to prescribe variable-rate fertilizer and what is the theory behind them? If farmers apply fertilizer at a variable rate, how should they evaluate those outcomes? Guests: Brad Carlson, Extension educator (Mankato) Daniel Kaiser, Extension nutrient management specialist (St. Paul) Jeff Vetch, Extension nutrient management researcher (Waseca) Additional resources: Variable rate nitrogen and nitrogen advisory tools: Do they work? Fertilizer recommendation technology: What is success? On-farm precision ag research update: In-season site-specific side-dress nitrogen rate recommendations for corn
