In 2023, the Ohio Agriculture Conservation Initiative (OACI) conducted a randomized sampling of 433 crop production fields within the HUC8 Sandusky watershed. A statistical approach was implemented to determine what practices are being used by farmers within this watershed to manage water and nutrients in the crop year 2022.
In the field survey process, all the cropped fields within the watershed were considered in the randomized selection process regardless of farm and field size. However, only fields that were greater than 20 acres were selected for the survey; the average size of the fields surveyed was 72.7 acres. A trained Soil and Water Conservation District employee interviewed the landowner or farm manager for each field surveyed. The Ohio State University and the Center for Survey Statistics and Methodology at Iowa State University helped in designing the sampling strategy and data analysis.
