WELCOMEMonitoring agricultural runoff

On-Field Ohio! (OFO) is intended to provide a long-term average estimate of field-scale erosion and phosphorus (P) runoff risk based on field properties (i.e. soil type, soil test P (STP), slope steepness) and farmer practices (i.e. crop management scenario (CMS), tillage and nutrient management). This allows farmers to prioritize time and resources to make effective management decisions. The output provides the user information regarding the amount and source of erosion and P loss which can be used to evaluate management practices to reduce nutrient loss.

The power is in the ability to evaluate erosion and P loss outcomes by comparing alternative crop management scenarios.  Comparing alternative OFO outputs illustrates how voluntary changes in practices can contribute to meeting water quality targets while maintaining agricultural production.
