Summary:
When is site-specific farming (SSF) profitable? What makes it profitable or not? This Guideline looks at both variable rate (VR) input applications and yield mapping. It demonstrates basic budgeting methods to measure average profitability. Profitability results from nine field research studies show that high-value crops give the biggest payoff to VR fertilizer application. Many yield map benefits come from whole-field improvements such as drainage, land leveling, windbreaks, and fencing. Farmers and agribusinesses should remember that because SSF practices are site-specific, their profitability potential also will be site-specific
