Study on Soil Magnetic Effect

摘要

A study on the effect of applied magnetic field was performed with six types of soils collected from northeastern China. Magnetic field was found to cause changes of soil physico-chemical properties and soil enzyme activities. An appropriate applied magnetic field could cut down soil zeta-potential, soil specific surface, soil water potential and soil swelling capacity; raise the charge density on soil colloids and the activities of invertase, hydrogen peroxidase and amylase in the soils; enhance soil aggregation and improve soil structural status and soil water-releasing capability.
