Crops and Livestock

Agriculture continues to play an important role in the economic base of Johnson County.

Most people would be surprised to know that about 45% of our land use in Johnson County is still devoted to agriculture. Grassland production for hay and pasture take up about 40,000 acres. Soybean production follows second at about 26,000 acres and corn comes in third at roughly 14,000 acres. Our primary livestock enterprise is cattle with both cow/calf operations and stocker cattle common. But Johnson County agriculture is diverse. We’re still home to large commercial agriculture as well as an expanding small part-time farming community. We grow and raise almost every traditional crop and livestock enterprise in the county, and have expanded into commercial fruit and vegetable production.

With our urban neighbors close by, agriculture has both its challenges and opportunities. One of those opportunities is to help people understand where their food comes from and the variety of ways it can be produced. With the help of local farmers, we use the media and events like Slice of Ag to educate and share our story.

Our staff works with individuals to address issues that impact their lives such as: small acreage management, pasture and forage management, pond management and water quality, crop and crop production, and home pest control.

No matter what you need, stop by, email or give us a call. We're here to help!
