The type of tillage in arable soils affects porosity of the soil and in consequence the hydraulic conductivity. The accessibility and mobility of organic carbon in arable soils can differ depending on...
Comparison of two- and three-electrode systems in measurements of potential oxygen flux density in soil*
soil aeration soil oxygen flux ODR OFD
2008/11/24
This paper presents a comparison of the results of potential flux of oxygen in soil, determined by the voltammetric method, OFD, with the use of a three-electrode set of electrodes in the system of po...
Chronovoltammetric determination of oxygen flux density in the soil
oxygen diffusion rate determination ODR of soil soil aeration oxygen flux density
2008/11/21
A chronovoltammetric method for the determination of oxygen flux density (OFD) in the soil is proposed. The method is based on the current-potential relationship recorded on a platinum indicator elect...
