What this means
What Bresser soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Bresser soils is neutral: pH 6.8 (most land between 6.7 and 6.8), the range most vegetables, flowers and lawn grasses prefer.
Loamy topsoil (loam, silt loam and similar) covers 98% of mapped Bresser acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is sandy loam (97% of mapped Bresser acres).
100% of mapped Bresser 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 2% of the acres in mapped Bresser soils very limited, 91% somewhat limited and 7% not limited.
Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
