Download Iowa Soil Saturated Hydraulic Conductivity (Ksat) Maps (gSSURGO)

Saturated hydraulic conductivity (Ksat) refers to the ease with which pores in a saturated soil transmit water. The estimates are expressed in terms of micrometers per second. They are based on soil characteristics observed in the field, particularly structure, porosity, and texture. Saturated hydraulic conductivity is considered in the design of soil drainage systems and … Continue reading Download Iowa Soil Saturated Hydraulic Conductivity (Ksat) Maps (gSSURGO)

Download Iowa Soil Bulk Density – one-third bar Maps (gSSURGO)

Bulk density, one-third bar, is the oven-dry weight of the soil material less than 2 mm in size per unit volume of soil at water tension of 1/3 bar (33 kPa), expressed in grams per cubic centimeter. Bulk density data are used to compute linear extensibility, shrink-swell potential, available water capacity, total pore space, and … Continue reading Download Iowa Soil Bulk Density – one-third bar Maps (gSSURGO)
