“…Clay participated in highly significant reduction of P T , especially P N , as well as significant diminution of aeration. The reduction of pores diameter due to increased clay content was also confirmed by Zangiabadi et al [2017]. In this study, clay also significantly affected the formation of P C and q CMC .…”

“…Generally, the horizons containing high percentage of clay suffer from poor aeration and soil is weakly permeable or impermeable for water [Heiskanen et al 2016]. On the other hand, higher content of sand in soil (profiles 5-7) allows easier water utilization by plants; however, it also accelerates the drainage and decrease the content of plant available water [Zangiabadi et al 2017]. Therefore, during long periods of drought, which is evident in southern Slovakia particularly during last twenty years [Ištoňa and Pavlenda 2011], trees can suffer from water deficiency.…”

Suitable soil and environmental conditions are the main prerequisites for successful growth of plants. Generally, all soil properties are substantially affected by textural composition. Therefore, the objective of the study was to test the interrelationships between particle size distribution and such physical soil properties, which usually predetermine the survival/death of plants, since they significantly affect the content and availability of water and air. Textural composition and physical soil properties were studied in profiles under monocultures of selected exotic trees in Arboretum Mlyňany, Slovakia. The results showed that medium-textured dominated in topsoils, whereas heavy-textured classes were dominant in luvic and stagnic horizons. Evaluation of entire profiles had confirmed standard, expected relationships between the individual grain fractions and soil physical properties. However, differences have occurred when the correlations between texture and physical properties in individual horizons were evaluated. Considering entire soil profiles, increased sand content significantly supported drainage of rainwater and soil aeration; silt contributed to increase the total porosity and aeration as well as available water capacity; clay contributed to the decrease in the available water capacity, total, and particularly coarse porosity and aeration, and to rise water retention, as well as the values of the wilting point. The results showed silt as key fraction providing suitable hydrophysical properties for the survival and growth of trees introduced in Arboretum. In compacted luvic and stagnic horizons, silt was significantly involved in the formation of total, and particularly coarse porosity and thereby increase soil aeration, while conversely, in loose topsoils just silt fraction significantly contributed to the reduction of coarse pores and increase of fine capillary pores and therefore water retention. In loose eluvial horizons, the silt contributed to significant increases in capillary porosity and water availability, which is essential in terms of meeting the plant needs.

“…Plant species with dense and fine roots such as grass (Deru et al, 2016) and highly mycorrhizal fibrous lateral root systems such as clover (Wyngaarden et al, 2015) both produce a range of soil pore sizes and increase micropore volume (Bodner et al, 2014;Jarvis et al, 2017). This can increase the water available to plants (Zangiabadi et al, 2017). As is commonly observed (van Groenigen et al, 2014) plant 652 growth was greater in the presence of earthworms (Table 4, Figure S10).…”

“…where θ s , θ m , θ FC , and θ PWP are the volumetric water contents corresponding to a pressure head of 0, 10, 100, and 15,300 cm, respectively [29]. According to Reynolds et al [46], the aforementioned water pressure head value (i.e., 100 cm) was considered to obtain the field capacity of several clay soils in agricultural [47,48] and forest [49] environments.…”

Conservation agriculture is increasingly accepted by farmers, but the modeling studies on agro-environmental processes that characterize these agricultural systems require accurate information on the temporal variability of the soil’s main physical and hydraulic properties. Therefore, specific investigations carried out in long-term experiments can increase our knowledge on the pros and cons of different measurement techniques. In this work, the simplified falling head (SFH) technique and the Beerkan Estimation of Soil Transfer (BEST) procedure were applied to investigate the temporal variability of some main soil physical and hydraulic properties, including bulk density (BD), field saturated hydraulic conductivity (Kfs), macroporosity (Pmac), air capacity (AC), plant available water capacity (PAWC), and relative field capacity (RFC). For this purpose, a long-term experiment was selected, and the experimental information obtained was used to verify the long-term impact (fifteen years) determined by two alternative forms of soil management, minimum tillage (MT) and no tillage (NT), for the cultivation of durum wheat. The main results of the comparison between MT and NT showed: (i) A comparable temporal variability in Kfs values when SFH was considered, given that in 75% of considered cases, the same result (i.e., significant or not significant) was obtained; (ii) a comparable temporal variability in Kfs values under MT (but not under NT) when both SFH and BEST were used, as a result of a possible Kfs,SFH overestimation under NT; (iii) differences in Kfs estimations by a factor of 6 or 7 (Kfs,SFH > Kfs,BEST) when comparable soil conditions (moisture and soil density) were considered; (iv) a comparable temporal variability when other soil indicators (BD, Pmac, AC, PAWC, and RFC) were simultaneously considered. After about fifteen years of field experiments characterized by continuous soil management and conducted with the methodological rigor typical of experimental farms, the SFH- and BEST-derived experimental information showed a substantial equivalence between MT and NT for the fine-textured soil investigated.
