The impact of the permanent grass cover or conventional tillage on hydraulic properties of Haplic Cambisol developed on paragneiss substrate

Abstract

This study is focused on the comparison of soil structure and soil hydraulic properties of a Haplic Cambisol on paragneiss under two different land managements. Soil samples were taken from all diagnostic horizons (A, Bw and C) of the soil profile under the permanent grass cover (grassland) and under the conventional tillage (arable land). Basic soil properties were measured. Aggregate stability was assessed using the WSA index. Soil composition was evaluated using micromorphological images. Tension disk infiltrometers with two diameters of 2.22 and 10.25 cm (and applied pressure head of −2 cm) and Guelph permeameter were used to measure unsaturated and saturated hydraulic conductivities, respectively. Soil hydraulic properties were measured in the laboratory using the multistep outflow experiment, which was performed on the undisturbed 100 cm

How various mulch materials can affect the soil hydro-physical properties

“…These parameters can be used to assess a physical quality of soils (e.g., Dexter, 2004a, b, c;Fér et al, 2016Fér et al, , 2018Fér et al, , 2020Jirků et al, 2013;Pavlů et al, 2021): if Sinf ≥ 0.05, the physical quality of soil (PQS) is very good; if 0.05 > Sinf ≥ 0.035, PQS is good; if 0.035 > Sinf ≥ 0.02, PQS is poor; and if 0.02 > Sinf, PQS is very poor. The bulk density (ρd) and total porosity (P) were determined on the undisturbed soil samples after measurements of the soil water retention curves by Dane and Topp (2002).…”

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

“…These parameters can be used to assess a physical quality of soils (e.g., Dexter, 2004a, b, c;Fér et al, 2016Fér et al, , 2018Fér et al, , 2020Jirků et al, 2013;Pavlů et al, 2021): if SINF < 0.02 PQS is very poor, if 0.02 ≤ SINF < 0.035 PQS is poor, if 0.035 ≤ SINF < 0.05 PQS is good, and if 0.05 ≤ SINF the physical quality of soil (PQS) is very good. However, it should be noted that different methods used for measuring the soil water retention curves can lead to different shapes of these curves (e.g., Gribb et al, 2004;Fér et al, 2018) and thus to different characteristics of the inflection point (Fér et al, 2018).…”

Simulation-based assessment of the soil organic carbon sequestration in grasslands in relation to management and climate change scenarios

“…Recent studies show the importance of identifying potential synergies between land-based adaptation and mitigation strategies, linking issues of SOC sequestration with emissions of GHGs and long-term sustainability of production systems within coherent climate policy frameworks [ [2] , [3] , [4] , [5] , [6] ]. The soil C cycle is furthermore central to the functioning of terrestrial ecosystems [ 4 , [7] , [8] , [9] , [10] , [11] ] and high SOC contents are also beneficial to soil functions relevant for agriculture, such as the regulation of nutrient-, water- and temperature flows and the soil structure [ [12] , [13] , [14] , [15] , [16] ]. Due to their year-round plant cover, high biodiversity and usually undisturbed soil, grassland areas are important ecosystems for SOC sequestration [ 10 , [17] , [18] , [19] , [20] , [21] , [22] , [23] ].…”
