Data Story

About Soil in Jones County, South Dakota

High Alkaline Clay Soils

Jones County soil is notably alkaline, with a pH of 7.33 that exceeds both the state and national averages. This chemical profile often requires specific crop selections that can tolerate higher lime content in the ground.

Dense Clay Foundations

Heavy clay at 39.2% defines the soil structure here, significantly impacting how the land breathes and drains. While this high clay content makes the ground harder to till, it provides excellent stability for heavy structures.

Managing Water Retention

Organic matter sits at 2.50%, which is better than the national baseline but trails the state average of 3.75%. The available water capacity of 0.142 in/in is also lower than the state benchmark, requiring careful moisture management.

Heavy Soil Drainage Needs

The dense clay composition typically leads to slower drainage and high water retention during heavy rains. Farmers and builders must account for this "heavy" soil when planning irrigation systems or building foundations.

Squash and Heavy Feeders

Zone 5a offers a solid window for gardening, even with the challenging soil texture. Focus on heavy feeders like squash or pumpkins that can thrive in clay-heavy environments with a little supplemental compost.
