HBC.Kandihumults

Key to Subgroups

HBCA. Kandihumults that meet all of the following:
1. Throughout one or more horizons with a total thickness of 18 cm or more within 75 cm of the mineral soil surface, have a fine-earth fraction with both a bulk density of 1.0 g/cm3 or less, measured at 33 kPa water retention, and Al plus 1/2 Fe percentages (by ammonium oxalate) totaling more than 1.0; and
2. In one or more horizons within 75 cm of the mineral soil surface, have redox concentrations, a color value, moist, of 4 or more, and hue that is 10YR or yellower and becomes redder with increasing depth within 100 cm of the mineral soil surface; and
3. In normal years are saturated with water in one or more layers within 100 cm of the mineral soil surface for either or both:
a. 20 or more consecutive days; or
b. 30 or more cumulative days. Andic Ombroaquic Kandihumults
Soil Families and Soil Series in Subgroup

HBCB. Other Kandihumults that have both:
1. Throughout one or more horizons with a total thickness of 18 cm or more within 75 cm of the mineral soil surface, a fine-earth fraction with both a bulk density of 1.0 g/cm3 or less, measured at 33 kPa water retention, and Al plus 1/2 Fe percentages (by ammonium oxalate) totaling more than 1.0; and
2. An ustic moisture regime. Ustandic Kandihumults

HBCC. Other Kandihumults that have, throughout one or more horizons with a total thickness of 18 cm or more within 75 cm of the mineral soil surface, a fine-earth fraction with both a bulk density of 1.0 g/cm3 or less, measured at 33 kPa water retention, and Al plus 1/2 Fe percentages (by ammonium oxalate) totaling more than 1.0. Andic Kandihumults
Soil Families and Soil Series in Subgroup

HBCD. Other Kandihumults that have, in one or more subhorizons within the upper 25 cm of the kandic horizon, redox depletions with a color value, moist, of 4 or more and chroma of 2 or less, accompanied by redox concentrations and by aquic conditions for some time in normal years (or artificial drainage). Aquic Kandihumults

HBCE. Other Kandihumults that:
1. Have, in one or more horizons within 75 cm of the mineral soil surface, redox concentrations, a color value, moist, of 4 or more, and hue that is 10YR or yellower and becomes redder with increasing depth within 100 cm of the mineral soil surface; and
2. In normal years are saturated with water in one or more layers within 100 cm of the mineral soil surface for either or both:
a. 20 or more consecutive days; or
b. 30 or more cumulative days. Ombroaquic Kandihumults

HBCF. Other Kandihumults that have 5 percent or more (by volume) plinthite in one or more horizons within 150 cm of the mineral soil surface. Plinthic Kandihumults
