What this means

What Barnes soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Barnes soils is neutral: pH 7.0 (most land between 6.8 and 7.0), the range most vegetables, flowers and lawn grasses prefer.

Loamy topsoil (loam, silt loam and similar) covers 100% of mapped Barnes acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is loam (95% of mapped Barnes acres).

100% of mapped Barnes acres is moderately well to excessively drained, which suits most garden plants.

For lawns and yards

Most land is in hydrologic groups B and C, where rain soaks in at a moderate pace.

For a septic system

For conventional septic absorption fields, NRCS rates 26% of the acres in mapped Barnes soils very limited, 75% somewhat limited and 0% not limited.

Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
