NitrateAgricultural Pesticide Use in Kansas
In the 2019 federal survey estimates, Kansas's most-applied agricultural pesticides statewide were Glyphosate, Atrazine and Metolachlor & Metolachlor-S. These estimates describe agricultural land use across the state — context for what's in use around the region, not a reading on any garden's soil.
Pesticide data: USGS NAWQA Pesticide National Synthesis Project (EPest county-level use estimates). Latest available county estimates: 2019.
County-Level Detail in Kansas
The federal record isn't uniform across a state. Here's what's documented around Kansas's counties with the densest records — each read from that county's own sites, not the state average. Proximity is information, not a diagnosis; a soil test settles any near neighbor.

Wyandotte County carries one of the heavier federal records we track — 1,301 documented sites, most of them underground storage tanks. That's a record of the area's history, not a verdict on any one yard: proximity to a documented site is information, not a diagnosis. Before food beds go in, a professional soil test tells you exactly what you're working with — and raised beds with clean imported soil grow well almost anywhere in the meantime.
