One of the key concerns about managing pests, and specifically weeds, is time requirements. This reflects not only agricultural demographics such as farm size, but also whether individuals have off-farm job responsibilities. The distribution of farm sizes represented in the survey responses approached a normal distribution (Table 1) and is representative of the farm size distribution in Iowa based on recent information from the National Agricultural Statistics Service.
