What this means

What Bowbells soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Bowbells soils is neutral: pH 6.7, the range most vegetables, flowers and lawn grasses prefer.

Loamy topsoil (loam, silt loam and similar) covers 100% of mapped Bowbells acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is loam (98% of mapped Bowbells acres).

100% of mapped Bowbells 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 23% of the acres in mapped Bowbells soils very limited, 77% 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.
