The project seeks to provide both localized and regional information to soybean producers across North Carolina on management practices that contribute to the ‘yield gap’ defined as the difference between maximum yield potential and realized soybean yield. These objectives will be achieved by working with other Southern USA states to gather production
information through a comprehensive survey and applying a biophysical spatial framework. These survey results will be used to identify causes of yield gaps across the Southern USA region and within North Carolina. If we can identify management practices that are contributing to the yield gap between maximum yield potential and realized yields, it will help our soybean producers focus on improving management to maximize soybean yield.

1. Identify key soybean management practices that explain soybean yield gaps in North Carolina

2. Collaborate with other Southern USA states to explain regional yield gaps and the largest contributing management factors

3. Further understand and explain drivers for observed management by environment interactions
