Link to this table

Soil texture Ideal bulk densities (g/cm3) Bulk densities that may affect plantgrowth (g/cm3) Bulk densities that restrict root growth (g/cm3)
sands, loamy sands <1.60 1.69 >1.80
sandy loams, loams <1.40 1.63 >1.80
sandy clay loams, loams, clay loams <1.40 1.60 >1.75
silts, silt loams <1.30 1.60 >1.75
silt loams, silty clay loams <1.40 1.55 >1.65
sandy clays, silty clays, clay loams with 35-45% clay <1.10 1.49 >1.58
clays (>45% clay) <1.10 1.39 >1.47
