Typical Reakor profile

Texture and pH by depth

Depth to scale. More strongly shaded layers hold more clay. Horizon names are the soil survey's (A = topsoil, B = subsoil, C = parent material).

What this means

What Reakor soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Reakor soils is moderately alkaline: pH 7.9. Acid-loving plants such as blueberries and azaleas struggle without amended beds, and some trees and shrubs show iron chlorosis (yellow leaves with green veins).

Loamy topsoil (loam, silt loam and similar) covers 97% of mapped Reakor acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is loam (47% of mapped Reakor acres).

100% of mapped Reakor acres is moderately well to excessively drained, which suits most garden plants.

For lawns and yards

On 93% of mapped acres, rain soaks in slowly (hydrologic groups C and D, including dual groups that are D until drained). Expect runoff and puddles after heavy rain: core-aerate compacted lawns and keep ground sloping away from foundations.

For a septic system

For conventional septic absorption fields, NRCS rates 100% of the acres in mapped Reakor soils very limited, 0% somewhat limited and 0% not limited.

Where the soil is very limited (slow permeability, a high water table, flooding, shallow bedrock or steep slopes), alternative systems such as mound or sand-filter designs are common and cost more.

Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
