A comparative study of some chemical and physical properties of Pineview, Vanderhoof and Nulki clay associations Farstad, Laurence

Abstract

A study of the chemical and physical properties of Pineview, Vanderhoof and Nulki soil associations in the Central Interior of British Columbia was related to field observations. The results of the chemical data on the whole soil as well as the colloid fraction (.002) show varying degrees of podsolic development due to variations in parent material. Pore-size distribution and particle-size distribution studies point out that the unfavourable physical properties associated with Vanderhoof soils are primarily the result of particle-size distribution and low organic matter content; the tight, impervious B horizon of Pineview clay is partially an inherited characteristic and partially developed. A simple modification of M.B. Russell's pore-size distribution apparatus is presented.
