Abstract

Magnetic susceptibility (MS) of paddy soils (Hydragric Anthrosols) and their corresponding dryland soils formed on the same parent materials in Zhejiang Province of Eastern China were measured in order to understand better magnetic profile discrimination and pedogenic magnetic minerals in paddy soils. Magnetic measurements showed that the MS values of paddy soils were much lower than those of dryland soils formed on the same parent materials. Paddy soils showed an obvious magnetic profile differentiation due to the difference in soil pedo-hydrological regimes. Three distribution patterns of MS profiles could be identified in paddy soils. The differentiation of MS in paddy soils can be used to describe soil profile characterization, identify diagnostic horizon, and interpret soil hydrological regimes. These results also help understand magnetic dynamic of soils caused by waterlogging process
