The Emerald Ash Borer (EAB) is an invasive insect that has been decimating ash trees throughout the Great Lakes states. It was first discovered in Minnesota in 2009 and is now found in four counties (Hennepin, Houston, Ramsey, and Winona). EAB poses a particularly serious threat to Minnesota because it is home to nearly 1 billion ash trees that occur throughout the state - the second most of any state.
Funding supports an Irrigation Specialist to develop guidance and provide education on irrigation and nitrogen best management practices (BMPs). In this position, Dr. Vasu Sharma provides direct support to irrigators on issues of irrigation scheduling and soil water monitoring. She is collaborating on the development of new irrigation scheduling tools that help irrigators manage water and nitrogen resources more precisely. These tools help reduce nitrogen leaching losses in irrigated cropping systems.
Native to the western United States and Canada, mountain pine beetle is considered the most devastating forest insect in North America. Trees usually die as a result of infestation and an unprecedented outbreak in the west is currently decimating pine forests there. While mountain pine beetle is not presently believed to reside in Minnesota, there are risks posed by an expanding species range resulting from warming climate and the potential for accidental introduction via lumber imports from infested areas.
PROJECT GOAL: Improve agricultural production and reduce flooding losses while minimizing the unwanted environmental impacts of subsurface drainage.
PROJECT OBJECTIVE: Demonstrate controlled tile drainage as a flood mitigation practice as well as the water quality and quantity benefits. The project is intended to set an example to increase the adoption of drainage water management practices in the Red River Valley.
Controlled drainage and a saturated buffer are both being evaluated as part of this project.
