What this means

What Manter soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Manter soils is neutral: pH 7.2 (most land between 7.0 and 7.4), the range most vegetables, flowers and lawn grasses prefer.

Loamy topsoil (loam, silt loam and similar) covers 66% of mapped Manter acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is fine sandy loam (46% of mapped Manter acres).

>99% of mapped Manter acres is moderately well to excessively drained, which suits most garden plants.

For lawns and yards

96% of mapped acres is in hydrologic group A, where water soaks in fast. Lawns there dry out quickly; deeper, less frequent watering and organic matter help.

For a septic system

For conventional septic absorption fields, NRCS rates 3% of the acres in mapped Manter soils very limited, 6% somewhat limited and 89% not limited (1% 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.
