Soil Health Partnership

National Corn Growers Association/Dr. Nick Goeser

The Soil Health Partnership is a farmer-led initiative fostering transformation in agriculture through improved soil health, benefiting both farmer profitability and the environment.

Established in 2014 by the National Corn Growers Association, we’ve built a network of working farms where we test, measure and share results of advanced farm management practices that will enhance sustainability and farm economics for generations to come. We collect long-term data on working farms in real growing conditions,

Hyperthermostable Enzyme (lactonases) for use as Microbial Biocontrol Agents for Plant Diseases

University of Minnesota/Dr. Michael Sadowski

Numerous bacterial pathogens infect crop plants, representing major economic burdens, and limit our ability to feed the world’s populations. Current methods for controlling plant diseases due to bacterial infection have had limited success, in part due to bacterial resistance and specificity. Novel strategies are therefore greatly needed to control microbes. Numerous bacterial pathogens use chemical signaling systems to coordinate virulence factor expression and biofilm formation. A common bacterial communication mechanism called quorum sensing (QS) regulates bacterial gene expression in response to fluctuations in cell density.

Enhancement of Survey Efforts for Corn Pests in Minnesota

University of Minnesota/Bruce Potter

Maintaining corn yield increases in the presence of new and evolving insect and pathogen pests has required sustained improvements in corn genetics, crop management practices and pesticides. Advances in insect resistant and herbicide tolerant GMO technologies combined with high corn values to create an environment where pest management was taken for granted. Insect, disease and weed control was often handled in a “one size fits all,” prophylactic manner. With more effective pest management and difficulties in interpreting survey data under widespread use of new GMO technologies,

Impact of Cover Crop Strategies on Productivity of Corn

University of Minnesota/Axel Garcia Y Garcia

The dominant crops in Minnesota are corn and soybeans; together, they are responsible for more than 80% of the $9.25 billion value of the state’s field and miscellaneous crops in 2014 (USDANASS, 2015). As part of the Midwest, the state is within one of the most intense agricultural areas in the world. Corn and soybeans, the main crops, are typically grown in rotation using conventional cropping practices, including high external inputs. The practice is under scrutiny due to issues with soil erosion and nutrient losses,

Maximizing Soil Warming and Health Under Different Tillage Practices in a Corn-Soybean Rotation

University of Minnesota/Jodi DeJong-Hughes

This is a multi-state effort involving Minnesota and North Dakota corn and soybean growers. This study is based on the following producer questions: What are the benefits of using chisel plow, vertical tillage and strip till on clay and/or loamy soils; how do I manage residue in each type of tillage system; can I achieve the same yields under all three types of tillage; and how does my choice in tillage practice affect the bottom line of my farming operation?
