Green Giant country

The Minnesota Valley Canning Co. was founded in Le Sueur in 1903, launched Great Big Tender Peas in 1925 and became Green Giant in 1950; the sugar snap pea was developed at its Le Sueur plant. Canning now happens in Montgomery, the Kolacky Capital of the World, where Seneca Foods runs a freezing and canning plant. Minnesota leads the nation in processing sweet corn and ranks second in green peas. Vegetable passes follow the processor's field program and label intervals.

Minnesota dicamba rules in 2026

For 2026, the Minnesota Department of Agriculture (MDA) set a June 12 cutoff for over-the-top dicamba on soybeans south of I-94, which includes Le Sueur County. No application is allowed above 85°F or when the forecast high tops 85°F, a 240-foot downwind buffer applies, and growers get at most two applications a year. With sweet corn and pea fields nearby, rescue passes are planned around those limits.

Minnesota's buffer law

Under the state buffer law, public waters need buffers averaging 50 feet, with a 30-foot minimum, and public ditches need 16.5 feet on each side. The Le Sueur Soil and Water Conservation District reviews every parcel on a three-year cycle and spot-checks at least 5% each year. Drone flight maps start from those buffer lines, so no pass crosses them.

Lake phosphorus projects

The Jefferson-German chain of lakes is impaired for nutrients, and its plan aims to cut loading by 58%, about 1,384 pounds of phosphorus a year, with water and sediment control basins, 800 acres of cover crops and restored wetlands. Lake Washington needs a 60% cut and has a project with 19 basins and 225 acres of cover crops. Drone-seeded cover crops go into standing corn and soybeans in late summer, ahead of harvest.

Cannon River headwaters and Sakatah

Tetonka Lake is the headwaters of the Cannon River, which widens into Sakatah Lake at the 842-acre Sakatah Lake State Park near Waterville, where Big Woods forest meets oak barrens. The Minnesota River forms the county's west line. Lakes, the river and the state trail are mapped as no-spray zones. Nearby quarries cut Kasota limestone, about 450 million years old, used inside the Minnesota State Capitol and at Target Field.

Fall nitrogen and water quality certification

Minnesota's Groundwater Protection Rule bans fall nitrogen from September 1 in vulnerable areas, and elsewhere MDA advises waiting until soils cool to 50°F. The voluntary Minnesota Agricultural Water Quality Certification Program had 1,910 producers on about 1.3 million acres by July 2026, with 10-year certainty for those enrolled. Every drone job comes with an application record for those files.

Licensing and airspace
