UMD Seeking On-Farm Research Partners

Maryland Grain Producer’s Utilization Board press release (abridged)

The Maryland Grain Producers encourages you to sign-up for one of the three new on-farm research trials for the 2023 growing season! Maryland grain check-off dollars are funding technical assistance through the University of Maryland and compensation to you, for this year’s on-farm research. Conducting this applied research on farms will lead to meaningful agronomic production data across the state at the field scale. The three different trials are listed below. Full protocols can be found online at

  • Nitrogen Rate – the study is evaluating corn yield response to a range of nitrogen application rates.
  • Biological Product Evaluation – the study is going to determine the impact of biological fertilizer enhancement products on corn yield.
  • Potassium Rate – the study will evaluate corn yield response to potassium fertilizer to determine the agronomic critical level and adjust land-grant fertilizer recommendations.

Dr. Nicole Fiorellino and Gene Hahn, the On-Farms Trials Coordinator, will be working directly with you to provide hands-on assistance throughout the entirety of the trial. Compensation is available to participating growers who complete the protocols on their farms.

Findings will be aggregated with no identifying information or location and shared for other farmers to see and learn more. Contact Dr. Fiorellino at (443) 446-4275 or to enroll today.

Considerations for Burndown Programs in 2023

Kurt Vollmer, Extension Weed Management Specialist, University of Maryland Extension

It’s that time of year when growers are considering which herbicides to include in their burndown programs. Utilizing effective herbicides will help to ensure less weed competition at planting. However, growers should consider not only...Read more about Considerations for Burndown Programs in 2023

Grid Sampling Soils to Improve Understanding of Soil Variability

Jarrod Miller, Extension Agronomist, and James Adkins, Irrigation Engineer, University of Delaware Extension

One method to uncover soil variability and crop response is to use precision soil sampling, including either grid or zone methods. Both increase the cost of taking soil samples, and each have their value depending on the desired outcomes...Read more about Grid Sampling Soils to Improve Understanding of Soil Variability

Survey: Nitrogen Management in the Chesapeake Bay Watershed

The University of Maryland Center for Environmental Science press release

What are your thoughts on nitrogen management in the Chesapeake Bay watershed? What can we do to reduce nitrogen pollution in the Bay while meeting the demands for nutritious food and economic development? Your thoughts are very important for us to identify barriers and opportunities for improving the Bay’s health! Thanks to our farmers, we have made progress in reducing nitrogen pollution reaching the Bay in the past few decades, but there is still more work to do.

If you live/work in the Chesapeake Bay Watershed and are over 18 years old, we would like to invite you to take a quick online survey (password: cafe2021) to share your thoughts. Our research team at the University of Maryland Center for Environmental Science developed this project to help understand and increase the region’s capacity to efficiently and profitably manage nitrogen across the food system, from crop and animal production, to distribution, to consumer waste treatment! Reducing nutrient loss depends on all parts of the food system, and participation of all different stakeholders like you!

This survey will take about 20 minutes. We will email the first 100 participants a $20 e-gift card. This survey is part of an NSF-funded project and it is approved by the University of Maryland Institutional Review Board ([1864028-3]. Sustainable nitrogen management across spatial and system scales). Please find more details about the project in the document attached. Any questions, please let us know. You can contact us via this email Thank you in advance for your contribution to the research project and the Bay’s health!

Best regards,
The CAFE Team
University of Maryland Center for Environmental Science

Hiring: Nutrient Management Advisors

The University of Maryland is looking to hire nutrient management advisors who are organized, have solid computer skills, and a great communicator, with a background in agriculture and/or resource conservation. Make a difference for farm productivity and Chesapeake Bay health. There are currently open positions in Allegany, Frederick, Montgomery, and Worcester Counties.

Nutrient management advisors develop nutrient management plans for agricultural producers to balance nutrient inputs with crop requirements, thus enhancing production potential, improving farm profitability, reducing excess nutrient inputs into the Chesapeake Bay and enabling producers to comply with the State of Maryland’s Water Quality Improvement Act of 1998. Responsibilities include:

  • Develop and deliver nutrient management plans using specially designed software and software applications;
  • Explain nutrient management planning and plans to agricultural producers;
  • Perform phosphorus-loss risk assessments when required;
  • Demonstrate proper techniques of soil and manure sampling for agricultural producers and, when appropriate, collect soil and manure samples;
  • Sample and analyze soils for nitrate-related tests;
  • Demonstrate and train agricultural producers in equipment calibration and crop yield measurements.

Visit to find links for the current openings. The best consideration date is 4/8/2023- submit your application today and share it with others who may be interested! All applications must be submitted online through This institution is an equal-opportunity employer.

Small Grain Disease Resources
