Very limited

75.4% of Kearney County, NE's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field.

Kearney County, NE is 516.193 square miles with a population of 6,749.

What Kearney County's reading doesn't cover

Two lots a mile apart in Kearney County can carry different soil, even though they share one countywide rating. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Kearney County will actually do.

What a system would cost here

With 75.4% of Kearney County rating "Very limited", a standard gravity system is not a safe assumption here. The engineered-system range, $10,000-$40,000 (mound or aerobic treatment), is the more realistic number to plan around, against $3,000-$8,000 for a conventional system on the rare lot that passes.
