The Farm Works Pro software package offers growers, ag retailers and custom applicators new tools for analyzing crop yields, creating profit/loss maps over multiple years, and entering formulas for prescription maps to drive variable-rate applications. They can use multiyear averaging to identify consistently high- and low-yielding areas to create history zones by field. Profit/loss mapping integrates financial information with precision maps to help the user analyze the impact of seed varieties, variable-rate applications and other parameters. Costs can be entered manually, or automated via Funds software.

Farm Works Pro requires Farm Works Trac and Site office software. The suggested retail price is $400. Contact Farm Works, Dept. FIN, Box 250, Hamilton, IN 46742, 800/225-2848, www.farmworks.com.
