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).
