“…In addition to their important hydraulic properties, Table 3 illustrates that the macro-pores create the soil air capacity (AC) through their easy draining under normal conditions [56,57]. Macro-pores and a high AC are very beneficial in lowland areas, where they counteract the development of anoxic soil conditions during rainy periods [58,59].…”

Soil hydraulic properties are very sensitive to land-use in regions susceptible to physical degradation. Intensive agricultural practices often lead to soil compaction and erosion in the investigated area. The main goal of this paper was to evaluate the impact of land-use on the pore size distribution and water retention in loamy soils. The soil water retention curve (SWRC) combined the total porosity and the water retention of the undisturbed sample at 3, 10, 31, 100, 310, and 1000 hPa suctions and the disturbed sample at 1.5 MPa. The triple-exponential model approximated the curve's course, and its derivative defined the distinct macro-, structural, and textural pore maxima, with characteristic suctions corresponding to SWRC inflection points. The soil organic carbon content had the greatest influence on the content of all three pore classes. The water retention properties followed the hierarchical pore size distribution in the four research plots and decreased in the identical orchard > forest > grassland > arable soil order. These results show that the orchard and forest areas are the most appropriate land uses with respect to porosity and water retention, while the grassland has not fully recovered after its conversion from arable soil and remains relatively poor, and the arable soil properties are the worst.

“…where w is the weight to be assigned to each parameter (subscript v is vegetation, gw is groundwater, s is soil, sl is slope and wb stands for surface water bodies), and R is the parameter scores given for retention in vegetation (R v ), groundwater bodies (R gw ), soil (R s ) and surface water bodies (R wb ), and for slope (R sl ) and soil sealing (R ss ). The values of the component factors of the equation were estimated from findings of other research projects in Hungary (Kertész, Á. et al 2010;Juhos, K. et al 2019). An indispensable precondition for the experiments carried out in the study areas was a Digital Elevation Model (DEM) of proper resolution.…”

Soil moisture retention on slopes under different agricultural land uses in hilly regions of Southern Transdanubia

Increasingly severe weather extremes are predicted as one of the consequences of climate change. According to climatic models, weather extremities induce higher risks for both flood and drought in the Carpathian Basin. Throughout the 19th and 20th centuries, flood control relied on cost-intensive engineering structures, but recently ecological solutions have come to the fore. Flood hazard on major rivers could be mitigated if multiple and cumulative water retention opportunities are exploited on the upper sections of tributary catchments. Appropriate land use and landscape pattern changes can shift the infiltration to run-off ratio to the benefit of the former. In the Transdanubian Hills of Southwest Hungary three study areas with different agricultural land use types had been selected and investigated for the impact of landscape micro-features on soil moisture retention capacity with the purpose of conserving water from wet periods for the times of drought. Marked differences in moisture dynamics have been detected between arable land, grasslands and orchards. This fact underlines the need for integrated soil and water conservation. Drought risk was found to be the highest on ploughland. Favourable soil water budgets have been observed in the fields as a function of land use: less intensive types, like grazing land and orchards (particularly tree rows), were identified as places of high water retention capacity. Although serious water stress conditions were also reached in the orchard, it markedly mitigated drought conditions compared to the ploughland.

“…Many studies use normalisation of indicator scores on the basis of linear or non-linear scoring functions (D'Hose et al 2014;Sharma et al 2005) and integrate the normalised indicators into SQIs using additive or multiplicative techniques (D'Hose et al 2014;De Laurentiis et al 2019;Lima et al 2013;Masto et al 2008;Sharma et al 2005). The statistical tests for confirming MDS include, amongst others, PCA and varimax rotation followed by simple linear regression (Juhos et al 2016), cluster analysis (Dilly et al 2018) and correlation, PCA and discriminant function analysis (DFA) (Juhos et al 2019). For SQI evaluation, some previous work has used either ANOVA or MANOVA to test associations between SQIs and soil management groups (de Andrade Barbosa et al 2019; de Paul Obade and Lal 2016; Kiani et al 2017;Molaeinasab et al 2018;Nakajima et al 2015).…”

“…Since soil physical, chemical and biological properties or processes vary spatio-temporally, the corresponding indicators included in SQIs inevitably varies among environmental settings and agricultural systems (Bai et al 2018;Doran 2002;Spiegel et al 2015). SQIs therefore need to be designed and interpreted as setting-specific (Biswas et al 2017;Juhos et al 2019;Raiesi and Kabiri 2016). But even in a given setting or agricultural system, it is important to characterise the heterogeneity of the relationships between physical, chemical and biological parameters (Dilly et al 2018).…”
