Deciding whether to fertilize cool-season pastures depends on several factors. Different grasses, such as bromegrass or western wheatgrass, respond differently to fertilizer.
Research from universities on sub-irrigated grazed hay meadows suggests that applying 70 lbs. of nitrogen (N), 25 lbs. of phosphorus (P), and 20 lbs. of sulfur (S) per acre can increase grass production by about three-quarters of a ton per acre.
This translates to a $150 potential increase in hay value, requiring only $56 per acre for fertilizer plus application costs, resulting in a 3:1 return on investment (ROI).
Nebraska grazing research shows that for every pound of nitrogen fertilizer applied, there is typically one pound of additional calf or yearling gain, assuming the application is within the University of Nebraska-Lincoln's (UNL) recommendations. These recommendations depend largely on expected extra grass growth, which is influenced by moisture levels.
Before deciding to fertilize, consider the following:
- The cost of fertilizer for your pasture.
- The pasture's production capacity.
- Expected cattle prices.
- Your historical margins.
These factors help producers make informed decisions on the feasibility and potential benefits of fertilizing. In areas with sufficient moisture and favorable market conditions, fertilizing might be a strategic investment to increase gains. For some, it may not be practical given their specific circumstances.
