“…Similar BD values found in the wheeled sub-area in contrast to the agricultural field suggest that the machinery compaction under SRC might not affect the topsoil properties as crop rotation practices. The BD found in the agricultural field was comparable to that described by Kreiselmeier et al [22] indicating that the influence of soil management (ploughing and seedbed preparation) can still be noticed at the beginning of the growing season for winter wheat.…”

“…Sampling was conducted in the end of March 2019. Since variations in soil structure are expected to be larger in the topsoil [22], we collected undisturbed soil cores (250 cm 3 ) from a depth of 0 to 5 cm. Undisturbed samples were taken, four in the agricultural site and nine in each SRC sites, by thoroughly removing the litter layer and small herbaceous vegetation.…”

“…The predictive model selected in the software on the basis of an appropriate representation of the curves was the bimodal version of the Kosugi's [29] and Mualem's [19] model which is based on the assumption of a lognormal distribution of the soil PSD [30]. The Kosugi bimodal model was selected in accordance with Kreiselmeier et al [22], since it is able to represent the structural and textural domains of the pore-size distribution. The parameters of this model have a physical meaning; therefore, it is adequate to assess the soil physical properties through its PSD [31].…”

In Europe, the establishment of short rotation coppice (SRC) systems for biomass production has been expanding in the last decades. Several studies have considered the impacts of SRC on soil properties; many have focused on studying its effect on biochemical properties while only a few have addressed physical and hydraulic properties. This study reports the assessment of soil physical and hydraulic properties on two SRC sites on sandy soils planted with 3-year-old poplar trees and an adjacent conventional agricultural field in Western Slovakia. All sites contain a comparable sandy loam soil texture and both SRC fields differed only in the groundwater accessibility. Water infiltration experiments were conducted in the field with subsequent sampling of the upper topsoil (0–5 cm depth). The samples were further processed in the laboratory to obtain the water retention and hydraulic conductivity functions of the soil covering a wide range of soil pore saturation. These hydraulic functions were fitted by using the bimodal version of Kosugi-Mualem’s hydraulic model to estimate the pore-size distribution (PSD) of the soils. The comparison between the SRC field neighboring the agricultural field and the latter showed similar hydraulic soil properties such as the topsoil water retention. However, macropore content, bulk density (BD) and infiltration capacity differed under SRC particularly in the tree row. Analogously, the two SRC fields showed similar topsoil water contents. Other soil properties differed presenting an increased macropore content and higher BD in the SRC field with distant groundwater connection. Our findings suggest that the SRC management may influence the topsoil properties.

“…While in the present study, tillage and crop stage only produced significant effects on soil capillary porosity but not on bulk density and penetration resistance (Tables 2 and 3). Under CT, pores over 50 μm in diameter decrease over time in the growth season, while under conservation tillage, enhanced biological activities (such as the growth and exudation of plant roots, soil animals and microorganisms) contribute to the formation and stabilisation of rounded pores (usually 30–500 μm in diameter) (Kautz, 2015; Kreiselmeier et al, 2019; Pagliai & De Nobili, 1993; Reichert et al, 2016). These effects may explain why the soil capillary porosity at the sowing stage was higher under CT than under conservation tillage but reverse result was observed at the harvest stage.…”

Conservation tillage is an alternative to conventional tillage (CT) for addressing the issue of soil degradation, while how it affects soil quality remains unclear. To characterise the temporary and stable effects of 8 years of conservation tillage on soil quality, topsoil (0-20 cm) properties, 16S rDNA-based bacterial community properties and their relationships were analysed. Three tillage practices (CT [as the control], subsoiling tillage [ST] and no tillage [NT]) were compared at the sowing and harvest stages of a continuous winter wheat (Triticum aestivum L.) system. The mean weight diameter of the water-stable aggregate, organic matter, total N/P/K and available K consistently improved with NT at both crop stages, with averages of 26.8, 35.3, 38.5, 29.2, 13.1 and 59.1%, respectively. Similar but lower levels of improvements were observed under ST. Tillage did not significantly affect soil bulk density, penetration resistance and temperature, whereas NT significantly decreased capillary porosity by 7.9% at sowing. At the sowing stage, CT showed higher bacterial α/β-diversity but lower soil water content and abundances of N-cycling bacteria. The physicochemical properties showed significant correlation with the abundances of some genera belonging to Proteobacteria, Nitrospirae and Actinobacteria. After 8 years of experimentation, we found that conservation tillage, especially NT, resulted in stable effects on soil aggregation and nutrient storage. Although soil compaction temporarily decreased after CT, the bacterial community, soil water storage and the aforementioned stable effects were more favourable for soil sustainability under conservation tillage.

“…Furthermore, soil water retention data from saturation to wilting point can be used to derive variables important to crop growth and that are influenced by variations in soil structure. In particular, the parameters of the Kosugi (1996) model defining the geometric mean ( r m ) and SD (σ) of the pore size distribution are sensitive to soil management in response to changes in the seasonal cycle (Kreiselmeier et al., 2019), as well as characteristics of the rooting system (Scholl et al., 2014).…”

Investigating the effects of various agricultural management systems on soil hydraulic properties in long‐term field experiments allows farmers to evaluate their efficacy in mitigating the effects of droughts and floods, which are expected to intensify in the coming decades. This study's main objective was to quantify soil structural and hydraulic properties in plots under organic manure, organic leguminous, and conventional agricultural management and related tillage practices at Rodale Institute's Farming Systems Trial. Soil cores were collected at depths of 0–10, 10–20, and 20–30 cm and analyzed for soil water retention, saturated hydraulic conductivity (Ksat), soil organic C (SOC), bulk density, and particle size distribution. Management practices had a measurable effect on SOC and bulk density, but not on Ksat, the parameters of the soil water retention model (rm and σ), or the calculated indicator water content values: field capacity (θfc), wilting point (θwp), plant available water (θpaw), and air capacity (θAirCap). Tillage practices (no‐tillage vs. tillage) had a measurable effect on SOC, bulk density and θAirCap, but not on Ksat, θfc, θwp, or θpaw. Significant differences by depth were observed for θfc, θwp, θpaw, θAirCap, SOC, and bulk density, but not for Ksat. Our results suggest that relatively minor differences between management practices may be insufficient for generating quantifiable differences in soil structure, and more substantial changes to management practices will be necessary to achieve the outcomes for developing climate‐resilient agricultural soils.
