February 23rd   - Planning for Fertilizer Efficiency to Maximize Savings Dr. Kitty O'Neil, Field Crops Specialist, CCE NCRAT

Plan ahead and plan thoroughly to minimize fertilizer costs in 2023.  We're all familiar with the 4R approach to maximizing fertilizer and nutrient efficiency, but we'll talk about the small details in its implementation, throughout the whole cropping system, to ensure accuracy and to minimize the need for purchased nutrients.

To register: 

March 2nd  - The Value of Manure Told Through Five Stories Dr. Quirine Ketterings, Cornell Nutrient Management Spear Program, & Kirsten Workman, Nutrient Management Specialist, PRODAIRY This presentation will share research results that answer the following questions: What is the fertilizer replacement value of manure?, How does injection of manure in alfalfa impact the crop?, Can shallow incorporation be as effective in conserving N as deeper incorporation?, Can no-till planting be compatible with manure injection?,  What is the carry over benefit of manure application?

March 9th - Corn Fertility in Times of Peak Fertilizer Prices

Janice Degni, Extension Field Crops Specialist

This seminar will outline a strategy for corn production that targets manure nutrients and purchased fertilizer where they are needed and conserving where needs are met by nutrient turnover from organic matter and drawing down previously built reserves.

March 16th - Small Grain & Soybean Fertility in Times of Peak Fertilizer Prices

Jeff Miller, Extension Field Crops Specialist, Oneida County CCE

We will discuss fertilization practices that optimize winter wheat production for grain and triticale production for forage. We will also discuss soybean production and fertilization practices that should be considered in corn grain / soybean rotations.

 To register:  


March 23rd - Hay Crop Fertility - A Foundation of Success

Dale Dewing, Sr Team Leader, WAP Nutrient Management. CCE Delaware County

Quality forage from hay crops is the foundation of profitably raising dairy and livestock, there is no substitute for good yields of good quality hay and silage.   If you're going to get this right, you'll need a solid plan for meeting the fertility needs of this humble, and sometimes over looked crop.  This workshop will help you make the most of your on-farm fertility sources, and sort through how to profitably use purchased inputs to get a good return on your investment.  We will consider needs of alfalfa, grass and mixed stands for all major nutrients as well as pH and lime. 

To register:


March 30th - Using Precision Technologies to Improve Nutrient Efficiency and Save Fertilizer Costs Manuel Marcaida, Subha Srinivasagan, Sunoj Shajahan, Quirine Ketterings (Nutrient Management Spear Program)

Advances in sensor technologies and analytical tools (machine learning and spatial statistics) now make it possible for farmers to be create management zones and make more informed decisions about crop inputs and nutrient management. In this session, we will talk about gathering high quality sensor-based data, creating yield maps and management zones for the farm, making use of grid-based soil To register:

NNYADP Biocontrol Research: Protocols Now Easier for Farmers and Applicators

Plattsburgh, New York. The Northern New York Agricultural Development Program (NNYADP) has announced the development of new protocols that make the use of New York-native persistent biocontrol nematodes for crop pest management easier for farms and custom applicators. The research developed a protocol for the mass-rearing and delivery of the persistent biocontrol nematodes and extended their shelf-life in a holding solution prior to field application.

"This research has expanded the use of persistent biocontrol nematodes as a nature-based method that helps reduce populations of alfalfa snout beetle, corn rootworm, and berry weevils that have the potential for costly economic damage, and reached significant milestones in making the application of persistent biocontrol nematodes more convenient for farmers and applicators," said NNYADP Co-Chair and dairy farmer Joseph Giroux, Plattsburgh, New York.

The new protocols developed by entomologist Elson Shields and research support specialist Tony Testa include a new liquid-based formulation that requires less water and less sawdust and achieves optimal ventilation and oxygenation with heat and humidity control for the mass-rearing of the persistent biocontrol nematodes.

The rearing technique developed earlier by Shields and Testa allows the northern New York-native persistent biocontrol nematode strains to retain their genetic ability to persist in soil for multiple years.

The researchers successfully used the new formulation to rear persistent biocontrol nematodes for application to 3,350 acres in field trials on farms in Jefferson and St. Lawrence counties in the spring and fall of 2022.

Seven farms participated in the on-farm application trials. Two commercial applicators evaluated the new field delivery and application methods.

"As a result of this Northern New York Agricultural Development Program research over time, I started my own persistent biocontrol nematode rearing lab in 2016. As a result of the field trials in 2022, I have adopted the new rearing and delivery protocols, which are more convenient, less costly, and less labor-intensive," said Mary DeBeer of DeBeer Agri-Service, Moira, New York.

Ron DeBeer of DeBeer Seed and Spraying assisted the field applications for the NNYADP project in 2022.

"As part of the persistent biocontrol nematodes field research in 2022, we applied to some fields that had had period infestation by alfalfa snout beetle and are now in a corn rotation. The much-improved delivery method and extended holding capacity allowed us much more flexibility in applying around the local weather constraints," said Dean Wheeler of D&D Spray Service, Mannsville, New York.

Over time, northern New York farm fields treated with the persistent biocontrol nematodes for management of alfalfa snout beetle began to show their impact on corn rootworm populations.

Subsequent research supported by the NNYADP, other funders, and farmers themselves has extended the use or trials of the persistent biocontrol nematodes to multiple crops in states nationwide.

The "Developing a Farmer/Applicator-Friendly Persistent Biocontrol Nematodes Formulation for Field Application" is posted at

Funding for the Northern New York Agricultural Development Program is supported by the New York State Legislature through the New York State Assembly and administered by the New York State Department of Agriculture and Markets.
