Are you an irrigator concerned about matching your irrigation with crop water use? Are you wondering how to improve water use efficiency and reduce water costs? The University of Minnesota Extension is offering the Minnesota Irrigator Program (MIP), to help answer these questions and more.

The three-day MIP will be held in person at the Dakota County Extension and Conservation Center in Farmington (same building as our office and Dakota County SWCD) on March 1, 8, and 15 from 8:30 am – 3:30 pm. Topics will include general water use and flow, irrigation sprinkler systems, variable rate irrigation, agronomics, maintenance, energy costs, and much more. Breakfast and lunch will be provided. Participation is capped at 25 individuals and the cost is $75. For more information and to register, go to https://z.umn.edu/MIP23registration.

MIP attendance is one of the requirements for the Irrigation Endorsement awarded by the Minnesota Agricultural Water Quality Certification Program and certified producers are eligible for tuition reimbursement. Contact your local MAWQCP certifier for more information.

Attend this workshop to learn best practices for lawn/turf maintenance with reduced environmental impacts. The practices taught will save you money and time and protect our water. Take the test to become Minnesota Pollution Control Agency Level 1 certified in turfgrass maintenance best practices. Participants will receive a Turfgrass Maintenance Manual.

Who should attend?

• Private maintenance companies
• Property managers
• Employees maintaining park, cemetery, city or school grounds

Training topics include:

• How turf management affects surface & groundwater
• Equipment calibration & maintenance
• Life cycle of turf & weeds & how it affects maintenance
• Efficient & effective irrigation
• Soil testing, fertilizer selection and application
• Mowing techniques
• Pesticide application tips
• Best practices for turf management
• Weed control practices
• In-field reference materials, such as turf care matrix

Pre-registration is required by 4 p.m. March 22. Register online at https://www.eventbrite.com/e/526531689457 or call 952-891-7000. Morning coffee and refreshments and lunch provided.

Funding by Dakota County and the Vermillion River Watershed Joint Powers Organization as well as the Minnesota Pollution Control Agency with Clean Water Funds.

This spring and summer, the Vermillion River Watershed Joint Powers Organization (VRWJPO) is leading an Alimagnet Lake alum (aluminum sulfate) treatment feasibility study. City of Burnsville and City of Apple Valley natural resources staff are also participating in the process. VRWJPO has hired a consultant, Barr Engineering, to conduct field work, analyze data and help put together the final feasibility report. This report is expected to be completed in July. We are hosting a public meeting on July 20, 2023 where the findings of the report will be presented.

What is an alum treatment?

An alum treatment is a common water quality improvement practice in shallow lakes that have excessive phosphorus and poor water clarity as a result of algae growth. Often times phosphorus is released into the water column from lake bottom sediments during the summer months. When alum is added to the water, it attaches to phosphorus and falls to the bottom of the lake, preventing it from feeding algae and improving water clarity. Increased clarity following alum treatments can also lead to increased aquatic plant growth, which help to keep phosphorus levels in check.

One of the first steps in planning for a potential alum treatment is to conduct a feasibility study, which will determine whether Alimagnet Lake is a good candidate for the treatment, and if it is, how to most effectively apply alum in the lake, and the estimated costs. The study will also look at alternative solutions to improve water quality, other than an alum treatment.

At the public meeting, there will be a short presentation to present the findings of the study and then time for attendees to ask questions or provide feedback on the findings. If alum treatment is determined to be a feasible option for Alimagnet Lake, VRWJPO would anticipate applying for a grant in late summer of 2023 to obtain funding to complete the work. No treatment would occur prior to 2024.
