Soybean Yield Gap Data Collection

Shawn Conley, State Soybean and Small Grains Specialist

Dear Wisconsin Crop Producers:

We am embarking on a Region‐Wide Project aimed at generating baseline producer data on current soybean management practices in Wisconsin’s production systems. This project is funded by the Wisconsin Soybean Marketing Board and the North Central Soybean Research Program (NCSRP). The project goal is to identify the key factors that preclude the State’s Soybean Producers from obtaining yields that should be potentially possible on their respective individual farmsThe term used for the difference between what yield is possible on your farm each year and what you yield you actually achieve is called a “Yield Gap”. We are therefore asking Crop Producers in Wisconsin to provide us with yield and other agronomic data specific to their soybean production fields. With that data, we will conduct an in‐depth analysis of what on‐farm factors might be causing a Yield Gap on your farms. To date we have collected data from across the North Central soybean production region from a total of 6251 soybean fields, representing 501,837 acres!!! Talk about BIG DATA!!!
