Who We Are

Our Mission

We are dedicated to a safe, sustainable, competitive food and fiber system and to strong healthy communities, families, and youth through integrated research, analysis, and education.

K-State Research and Extension — Cooperative Extension Service

All universities engage in research and teaching. But the 100 land-grant colleges and universities across the country have a third critical mission — extension.

The national Cooperative Extension Service was created with the passage of the Smith-Lever Act in 1914. The service was created to assure that research-based knowledge developed by the land-grant universities got delivered to the people at the county level.

Along with research and teaching, land-grant institutions “extend” their resources through non-formal, non-credit educational programs.

Johnson County, Kansas

As the local branch of Kansas State University Research and Extension (Kansas' land-grant university), this Extension Office has served Johnson County citizens since 1917.

We have access to the latest science, research and technology on subjects in five program areas. Our agents are university faculty. Their role is to encourage the application of this research-based information to help improve the quality of life for our residents.

We make the university’s expertise available to you and help you apply it to your needs. You can trust that the information we provide is

  1. research-based,
  2. expert and
  3. presented without bias.

Our Partners

Johnson County Extension is a unique partnership with Kansas State University, Johnson County government, and the United States Department of Agriculture (USDA) Cooperative Extension Service.
