Soil Adaptability

Rating Soil Category
E
Light Soils

LOW CEC (<10); OM <1.5%; low water-holding capacity; non-irrigated sand; marginal productivity; drought prone.

E
Medium Soils

CEC 11–18; OM 1.5-3.5%; well-drained; silt loam; high productivity.

E
Heavy Soils

High CEC (>18); OM >3.5%; poorly-drained; high clay content; gumbo; muck.

G
Poorly-Drained Soils

Soils that have the potential to remain saturated for prolonged periods; side hill seeps; gumbo muck.
