What this means

What Nauvoo soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Nauvoo soils is strongly acidic: pH 5.3 (most land between 5.0 and 5.5). Most vegetables and lawn grasses do best around 6.0 to 7.0, so lime is often needed; blueberries, azaleas and rhododendrons like it as it is.

Loamy topsoil (loam, silt loam and similar) covers >99% of mapped Nauvoo acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is fine sandy loam (69% of mapped Nauvoo acres).

100% of mapped Nauvoo 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 30% of the acres in mapped Nauvoo soils very limited, 70% 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.
