Estimation of the stability of topsoil aggregates in areas affected by water erosion using selected soil and terrain properties

The stability of soil structure is crucial for providing most of the essential functions of soil. In our previous research in a region of Chernozem soil, multiple linear regression analysis showed that soil aggregate stability within this morphologic...

Using scaling factors for characterizing spatial and temporal variability of soil hydraulic properties of topsoils in areas heavily affected by soil erosion

Extensive agricultural use of land coupled with intensive water erosion at geomorphologically diverse areas with uniform soil substrate and originally similar soils can lead to high diversity in soil types and, correspondingly, to a high spatial and ...

Variability of topsoil hydraulic conductivity along the hillslope transects delineated in four areas strongly affected by soil erosion

Soil hydraulic conductivities of topsoils were studied at 5 points of the hillslope transects delineated at 4 geomorphologically diverse areas, where the original soil types Chernozem, Luvisol and two Cambisols were due to erosion transformed into di...

Influence of soil-water content on CO2 efflux within the elevation transect heavily impacted by erosion

This study focused on the effects of organic carbon contents and soil-hydraulic conditions on CO2 efflux. Samples were collected at 5 positions (summit, shoulder, backslope, footslope andtoeslope) of the elevation transect affected by erosion and the...

Simple but efficient signal pre-processing in soil organic carbon spectroscopic estimation

As there is no single (or combination of) signal pre-processing method that works best with all data sets, choosing the most feasible one is a key aspect in soil diffuse reflectance spectroscopy in the visble- and near infrred region. The commonly us...

Ensemble predictive model for more accurate soil organic carbon spectroscopic estimation

A myriad of signal pre-processing strategies and multivariate calibration techniques has been explored in attempt to improve the spectroscopic prediction of soil organic carbon (SOC) over the last few decades. Therefore, to come up with a novel, more...

Combining reflectance spectroscopy and the digital elevation model for soil oxidizable carbon estimation

As soil oxidizable carbon has several different absorptions in the visible and near infrared region due to its complex composition, multivariate calibration techniques such as multiple linear regression, partial least squares regression, support vect...

Root distributions in a laboratory box evaluated using two different techniques (gravimetric and image processing) and their impact on root water uptake simulated with HYDRUS

Knowledge of the distribution of plant roots in a soil profile (i.e. root density) is needed when simulating root water uptake from soil. Therefore, this study focused on evaluating barley and wheat root densities in a sand-vermiculite substrate. Bar...

Using magnetic susceptibility mapping for assessing soil degradation due to water erosion

This study focused on developing a method for estimating topsoil organic carbon content from measured mass-specific magnetic susceptibility in Chernozems heavily affected by water erosion. The study was performed on a 100 ha area, whereby 202 soil sa...
