What this means
What Crider soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Crider soils is slightly acidic: pH 6.2 (most land between 5.9 and 6.9), the range most vegetables, flowers and lawn grasses prefer.
Loamy topsoil (loam, silt loam and similar) covers 97% of mapped Crider acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (96% of mapped Crider acres).
>99% of mapped Crider 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 16% of the acres in mapped Crider soils very limited, 81% somewhat limited and 0% not limited (3% 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.
