A quantitative comparison of Soil Development in four climatic regimes A quantitative comparison of Soil Development in four climatic regimes
A new quantitative Soil Development Index based on field data has been applied to chronosequences formed under different climatic regimes. The four soil chronosequences, developed primarily on sandy deposits, have some numeric age control and are located in xeric-inland (Merced, Calif.), xeric-coastal (Ventura, Calif.), aridic (Las Cruces, N. Mex.), and udic (Susquehanna Valley, Pa.)...

A quantitative index of soil development from field descriptions: Examples from a chronosequence in central California A quantitative index of soil development from field descriptions: Examples from a chronosequence in central California
A soil development index has been developed in order to quantitatively measure the degree of soil profile development. This index, which combines eight soil field properties with soil thickness, is designed from field descriptions of the Merced River chronosequence in central California. These eight properties are: clay films, texture plus wet consistence, rubification (color hue and...
