Lime cost affects the economics of nitrogen use

Farmers have used significant quantities of nitrogen on their cool-season forages. This practice has been shown to acidify the soils over time. We conducted an economic study to determine the effect of considering the cost of lime on the current recommendations about the optimal level of nitrogen.
