Soil Horizon Parameters:

Bottom Depth of Horizon : Each soil horizon will be divided into a number of simulation layers depending on thickness

Percent Clay : Percent clay for each soil horizon (% clay + % sand + % silt must equal 100 %)

Percent Sand : Percent sand for each soil horizon

Percent Silt : Percent silt for each soil horizon

Percent Organic Matter : Percent organic matter for each soil horizon

Bulk Density : Soil density for each soil horizon. Typical value: 1.10 to 1.5 g/cm3



The following parameters can be optionally computed by selecting the "GO" button:

Saturated Water Content : Water content at soil saturation

Saturated Conductivity : Hydraulic conductivity at soil saturation Typically 0.1 to 10 cm/hr

Air Entry Potential : Water tension at which largest soil pores drain. Typical value: 0.004 to 0.0 bars

Pore Size Index : Index of soil pore-size distribution. Typical value: 3.0 to 5.5
