What this means
What Nanford soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Nanford soils is strongly acidic: pH 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 100% of mapped Nanford acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (85% of mapped Nanford acres).
100% of mapped Nanford 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 46% of the acres in mapped Nanford soils very limited, 54% 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.
