What this means
What Norge soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Norge soils is moderately acidic: pH 5.9 (most land between 5.6 and 6.5). Many vegetables grow well here, and some gardens benefit from a little lime. Test before adding any.
Loamy topsoil (loam, silt loam and similar) covers 89% of mapped Norge acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (72% of mapped Norge acres).
100% of mapped Norge 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 38% of the acres in mapped Norge soils very limited, 51% somewhat limited and 0% not limited (11% not rated, such as urban land, pits or water).
Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
