Název v původním jazyce

Monitoring of the vertical distribution of the magnetite tracer in a shallow soil profile

Popis výsledku v původním jazyce

Magnetic iron oxide, a black powder of a moderate prize, has been used as a soil erosion tracer within the researchactivities on various scales. The tracer binds to soil aggregates and can be easily, and relatively cheaply, detectedvia its contrasting magnetic properties (e.g. magnetic susceptibility). Previous research indicates that the tracer is immobile in vertical direction during short term experiments, therefore only a little attention has been payed to the vertical extend of the tracer detectability. For studies related to tillage erosion, depth of deposited sediments after an erosion event, or for the description of the Vertisols self-mulching process, the position and distribution of the magnetite tracer within the soil profile is essential. Traditionally two methods to measure the magnetic susceptibility have been used: (i) laboratory analysis of soil samples; (ii) surface probe that integrates the magnetic signal from the shallow soil. But it is unclear into which depth does the surface probe detect the signal and how does the different distribution of the magnetic material affect the measurement of the probe.
