Abstract
Magnetic susceptibility (χ) of soils is easily measured; however, the link between magnetic horizonation and pedogenic factors needs to be clarified. This study compares the χ of the A and C horizons of 89 generally well-drained profiles from the agricultural area of Saskatchewan to quantify the effects of parent material and climate. Total Fe and Mn were only weakly related to χ, but χ increased as the soil texture became coarser. This trend was more noticeable in parent material than topsoil samples, and stronger for till than for fluvial, lacustrine and aeolian parent materials. The A horizon samples showed enhanced low frequency and frequency dependant χ. This increase in topsoil χ was greatest in the more humid areas. Key words: Magnetic susceptibility, parent material, climate, texture, magnetic enhancement, soil zone
