The USDA Agricultural Research Station (ARS) in Kimberly, Idaho, one of eight research institutions across the U.S. conducting studies for the Dairy Soil & Water Regeneration (DSWR) project, will host a field day Sept. 3 to share its latest research and spotlight DSWR.
DSWR is an eight-year initiative studying the impact of dairy feed production on soil health, water quality and quantity, greenhouse gas emissions and agronomic factors such as yield and forage quality. Initiated by Dairy Management Inc. (DMI) and the Soil Health Institute with research partners in six key dairy states, the project is largely supported by the Foundation for Food and Agriculture Research, which awarded $10 million towards this work, and matching funds from companies like DMI, Newtrient, Nestlé and Starbucks.
The DSWR studies in Idaho are investigating the impact of novel manure products — evaporated and flocculated solids — in soils with and without a history of manure application in a corn silage and triticale rotation. Additionally, the research site is evaluating the nitrogen fertilizer replacement value of manure.
Farmers, nutrient management planners, crop consultants, agronomists and other industry professionals are invited to join the USDA ARS researchers and their project partners to learn about the collaborative research efforts to help the dairy industry address resource challenges and advance its 2050 environmental stewardship goals.
Topics will include:
- Manure byproducts as fertilizers
- Manure priming
- Deficit irrigation
- Phosphorus drawdown
- Methane potential of manure
- Results from Idaho’s participation in Task 1 of DSWR – a survey of soil health and soil carbon on Idaho dairy farms
