Corn Cropping Systems To Improve Economic And Environmental Health, Heather Darby, Lindsey Ruhl, Rory Malone, Sara Ziegler

Northwest Crops & Soils Program

In 2020, UVM Extension’s Northwest Crops & Soils Program continued a multi-year trial at Borderview Research Farm in Alburgh, VT to assess the impact of corn cropping systems on overall health and productivity of the crop and soil. Management choices involving crop rotation, tillage, nutrient management, and cover crops also make differences in the long term. Yields are important and they affect the bottom line immediately and obviously. Growing corn with practices that enhance soil quality and crop yields improves farm resiliency to both economics and the environment. This project evaluated yield and soil health effects of five different corn …

Sare Interseeding Cover Crops In Corn Silage Cropping Systems, Heather Darby, Sara Ziegler, John Bruce, Lindsey Ruhl

Northwest Crops & Soils Program

With increasing focus on minimizing environmental impacts from agriculture, farmers are looking for strategies that are good for farm and environmental viability. Cover cropping is one strategy that has been promoted to help farms improve soil health and minimize soil and nutrient losses to the environment. However, with a short growing season it is often difficult to get an adequate cover cropping following corn silage harvest. Therefore, farmers are interested in using interseeding techniques to establish cover crops into an actively growing corn crop. Being successful with this practice will likely require changes to other aspects of the cropping system …

Vermont Organic Silage Corn Performance Trial, Heather Darby, Ivy Krezinski, Rory Malone, Sara Ziegler

Northwest Crops & Soils Program

The University of Vermont Extension Northwest Crops and Soils Program conducted an organic silage corn variety trial in 2020 to provide unbiased performance comparisons of commercially available varieties. To determine varieties that are best suited to this production system and our region’s climate, we evaluated 9 commercially available organic corn silage varieties. It is important to remember that the data presented are from a replicated research trial from only one location in Vermont and represent only one season. Crop performance data from additional tests in different locations and over several years should be compared before making varietal selections.

Integrating Cover Crops And Manure Into Corn Silage Cropping Systems, Heather Darby, Sara Ziegler, John Bruce, Ivy Krezinski, Rory Malone, Lindsey Ruhl

Northwest Crops & Soils Program

With increasing focus on managing environmental impacts from agriculture, farmers are looking for ways to manage nutrients efficiently on their farms without sacrificing crop productivity. Cover cropping and no-till crop production are strategies that have been promoted as methods that help retain nutrients on farms and minimize losses to the environment. However, integrating these practices into the cropping system requires changes to other aspects of the system. For instance, manure management becomes more difficult when using no-till production methods as the timing or method of application may need to be altered to fit appropriately into the new production system. Farmers …

Vermont Non-Gmo Corn Silage Performance Trial, Heather Darby, Ivy Luke, Rory Malone, Sara Ziegler

Northwest Crops & Soils Program

In 2020, the University of Vermont Extension Northwest Crops and Soils Program evaluated yield and quality of six non-GMO corn silage varieties at Borderview Research Farm in Alburgh, VT. To successfully transition to growing non-GMO corn, farmers are looking for more information on non-GMO varieties that are available and perform well in our region. While the information presented can begin to describe the yield and quality performance of these non-GMO corn silage varieties in this region, it is important to note that the data represent results from only one season and one location.

Closing The Nutrient Loop Through An Innovative Organic Fertilizer Technology Field Tested For Corn, Heather Darby

Northwest Crops & Soils Program

Excess nutrients from agricultural, industrial, and wastewater runoff result in harmful algae blooms in rivers, lakes, and the ocean. Inorganic nitrogen and phosphorous can fuel the rapid growth of algae, which deprives the aquatic environment of oxygen and sunlight. This process, eutrophication, results in anoxic “dead zones” and threatens ecosystems and access to clean water.

In agriculture, this nutrient pollution can be controlled by implementing and improving practices that reduce runoff, such as building good soil structure and not over-fertilizing nitrogen and phosphorus using slow release fertilizers.
