Cover crops are an important tool in preserving and increasing soil productivity, stewarding water resources, suppressing weeds and retaining nutrients. However, planting cover crops coincides with the busy harvest season. Also, research to influence best practices for successful cover crops has been limited across the vast Illinois growing environments.
This project will implement two different trials to inform how cover crops can best fit within a soybean/corn rotation:
Cereal rye after corn harvest before no-till soybean
Different clover species after soybean harvest before no-till corn
The trials will assess optimal planting windows, seeding rates, and termination timing to maximize overwintering; biomass production; and rotational crop stand, growth and yield.
To be able to determine the relationship between seeding rate and planting date on cereal rye stand quality and biomass production to better understand how to prescribe different seeding rates based on planting date and region to achieve a desired level of biomass. Also, this research will increase understanding of how these biomass differences influence soybean stand and yield.
To be able to determine the optimal date window for these clovers across the state for successful winter survivability and biomass production and performance and yield of the following corn crop.
The SOYLEIC breeding effort is a collaboration with breeders at other universities.
The Illinois breeding program collaborates with the Missouri Soybean Merchandising Council (MSMC) to coordinate testing and seed increases of elite SOYLEIC experimental lines to increase the speed that varieties are released.
The MSMC team also works with seed companies, processors and the food industry to increase demand for SOYLEIC oil.

The Illinois Soybean Association (ISA) checkoff and membership programs represent more than 43,000 soybean farmers in Illinois. The checkoff funds market development and utilization efforts while the membership program supports the government relations interests of Illinois soybean farmers at the local, state, and national level, through the Illinois Soybean Growers (ISG). ISA upholds the interests of Illinois soybean producers through promotion, advocacy, and education with the vision of becoming a market leader in sustainable soybean production and profitability.
