Calculating The Soybean Yield Gap for WI Soybean Farmers

Shawn P. Conley, Soybean and Wheat Extension Specialist

We are embarking on Year #2 of a State‐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 farms. The 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. You can find the survey below. With that data, we will then conduct an in‐depth analysis of what on‐farm factors might be causing a Yield Gap on producer farms. We intend to provide annual reports to all crop producers informing them of what factors we may have identified that, based on our analysis of the data collected from farms, are likely limiting you from achieving soybean yields closer to yield potential that is likely possible on your farms! These results will be presented at our 2017 Area Soybean meetings held in January 2017 and at Corn Soy Expo! Here is a link to the introductory data we collected in 2015! 2015 Yield Gap Summary Data

Below please find links that are also on my webpage that describe the process, the guidelines for data collection, as well as the data collection form. Please know that this data will not be shared individually and your information will be held strictly confidential. Please let me know if you have any questions or concerns regarding this request. Please return all completed forms to my address below! Due to several requests I have also attached a fillable pdf version for ease of data entry.
