Conservation Practices

ABOUT

The core components of conservation management are cover crops, crop rotation, and minimal or no tillage. While they sound simple enough, implementing them on your farm while maintaining crop productivity and profitability is complicated. Research projects in our Conservation Practices category investigate the many aspects associated with adopting these practices so you can reach the conservation goals you set for your farm.

Controlled-Release N, P & K Fertilizer Management in Strip-Till 30” Rows and No-Till 15″ Rows for High-Yield SoybeansMarlee Silberman2024-11-05T10:22:10-06:00

Controlled-Release N, P & K Fertilizer Management in Strip-Till 30” Rows and No-Till 15″ Rows for High-Yield Soybeans

This project aims to better understand how strategic nutrient management can impact soybean yield across northern and central Illinois. It will evaluate different nutrient strategies under no-till, strip-till, 15” rows, 30” rows, with cover crops, and without cover crops. Data will be used to inform future year trials and ultimately provide farmers with best management practices for nutrient management in soybean crops.

Adaptive Management for Maximizing Soybean Production Following Cereal Rye TerminationMarlee Silberman2024-11-05T10:42:32-06:00

Adaptive Management for Maximizing Soybean Production Following Cereal Rye Termination

Trials in this multi-year project will help researchers better understand 1) how cereal rye influences nitrogen (N) and sulfur (S) availability and soybean uptake, and 2) evaluate soybean yield response to N and S fertilization, alone and in combination, after a cereal rye cover crop.

How Can I Become More Confident in Identifying Conservation Practices That Will Positively Impact Crop Productivity and Related Environmental Factors on My Farm?Marlee Silberman2024-11-05T10:23:03-06:00

How Can I Become More Confident in Identifying Conservation Practices That Will Positively Impact Crop Productivity and Related Environmental Factors on My Farm?

This project aims to quantify the benefits of adopting conservation management practices at the field level. This includes how various conservation practices impact crop productivity, greenhouse gas (GHG) emissions, soil carbon sequestration and N leaching/water quality across the various soybean regions in Illinois. Project output will include reports farmers can use to inform their management decisions and help prepare them to take advantage of ecosystem markets, like carbon credit programs.

How Can I Offset Some of the Potential Challenges When Planting Soybeans Into Heavy Corn Residue?Alison McKenney2024-11-05T10:31:26-06:00

How Can I Offset Some of the Potential Challenges When Planting Soybeans Into Heavy Corn Residue?

To help more farmers feel confident implementing conservation tillage systems, this project is investigating the interactions across soil types, starter fertilizer, tillage systems and row spacings and how they affect soybean growth, nutrient uptake, and seed yield and quality. The results will help farmers identify management practices that enable them to plant soybeans into heavy residue while preserving the crop’s yield potential.

What Is the Ideal Planting Window To Establish Cover Crops and Obtain Optimum Crop Growth and Yield of Rotational Crops?Alison McKenney2024-11-05T10:30:04-06:00

What Is the Ideal Planting Window To Establish Cover Crops and Obtain Optimum Crop Growth and Yield of Rotational Crops?

This project is comparing 1) different cereal rye seeding dates and rates before soybean, and 2) different planting dates of two clover species after soybean harvest and ahead of corn. Farmers will gain better insights into cover crop planting and seeding rate recommendations and best management practices for adding cover crops to their cropping systems.

Which Practices Help Improve Soil Health and Water Quality While Also Giving Me the Ability To Take Advantage of Ecosystem Markets Like Carbon Credit Programs?Alison McKenney2024-11-05T10:17:15-06:00

Which Practices Help Improve Soil Health and Water Quality While Also Giving Me the Ability To Take Advantage of Ecosystem Markets Like Carbon Credit Programs?

This project is collecting soil health, water quality and climate footprint metrics across the state’s growing regions and cropping systems (soy-corn, double-crop wheat-soy with corn rotations). It will help inform practice-based recommendations that protect soil health and water quality, as well as provide insights farmers can use as they explore ecosystem credit programs.

How Much Do Crop Residues Feed the Following Crop’s Nutritional Needs?Alison McKenney2024-11-05T10:12:44-06:00

How Much Do Crop Residues Feed the Following Crop’s Nutritional Needs?

Crop residue is a source of nutrients for the following season’s crop, but it has yet to be documented just how much of which nutrients the residue provides. This project aims to track the release of nitrogen (N), potassium (K) and sulfur (S) from corn, wheat and cereal rye residue for soybean uptake. It will also assess how tillage and biologicals that breakdown residue influence nutrients released from residue for soybean uptake.

How Can Cover Crop Adoption in Targeted Zones Impact Nutrient Loss Reduction?Alison McKenney2024-11-05T10:10:50-06:00

How Can Cover Crop Adoption in Targeted Zones Impact Nutrient Loss Reduction?

When faced with non-point nutrient loss reduction goals, it truly does take a village. Farmer-led watershed groups are critical to drive cover crop adoption in watershed hot spot areas. Through this project, researchers will use historic and current water quality and conservation practice data for the Lake Bloomington and Evergreen Lake watersheds to conduct a “Nutrient Loss Risk Analysis” that pinpoints high and low risk nutrient-loss zones. They will share the high-risk hot spots with farmer-led watershed groups and agencies, as well as deliver educational resources to help area farmers adopt cover crops and other practices to mitigate nutrient loss.

Can following the MRTN approach reduce tile nitrate loss in conventional and cover cropping systems?Alison McKenney2024-11-05T10:32:09-06:00

Can following the MRTN approach reduce tile nitrate loss in conventional and cover cropping systems?

Based on year 1 insights, this year 2 project will focus on validating the maximum return to nitrogen (MRTN) approach as a viable method to determine N rates for corn in a corn/soybean rotation both with and without cover crops. This is particularly important in the tiled fields of central Illinois where it is critical to reduce nitrate loss.
