Survey to help Michigan soybean producers identify and overcome yield gaps
Michigan soybean producers have the opportunity to help researchers and agronomists identify and overcome barriers to higher soybean yields by participating in a volunteer survey.
Soybean yield increases in Michigan and across the North Central United States have not kept pace with those of crops such as corn, wheat and sugarbeets. Producers, researchers and agribusiness agronomists are aware of this situation. However, the specific yield-limiting factors responsible for the creating the yield gaps (difference between attainable and actual yields) are not fully understood. The most common approach to identifying yield-limiting factors has been through the use of well-designed on-farm and small plot research projects. While the information collected from these projects has increased our knowledge of some of the yield-limiting factors, it has not identified all of them or provided enough information regarding soil and weather effects to develop reliable recommendations for overcoming them and narrowing yield gaps.
An alternative or complementary approach for identifying soybean yield-limiting factors has been successfully implemented in Nebraska. The project collected information about yields, crop inputs and management practices for specific fields from producers across the state. The researchers were able to obtain this information from 516 fields between 2010 and 2012. The large amount of information gathered from representative fields enabled the researchers to identify individual crop inputs and management practices that significantly affect soybean yields.
The Nebraska project was so successful, the North Central Soybean Research Program has provided funding to expand the project in states throughout the North Central region. This means Michigan soybean producers will have the opportunity to supply yield and management information about their fields that will be used to generate specific recommendations for achieving higher soybean yields in the future. The project also includes a benchmarking aspect enabling participating producers to confidentially compare their soybean yields and management practices to those of other producers across Michigan and identify specific opportunities for fine-tuning their management practices to close the yield gap on their farms.
How to participate
Again, your participation in this important project is voluntary and all the information you provide will be kept confidential. The information from all the surveys will be used to identify yield-limiting factors, their interactions with soil and weather conditions and opportunities for increasing soybean yields in Michigan.
