“…Wahl et al (2004) found a correlation of the infiltration values with the macroporosity depending on the dynamic of CT in time, being the initial mechanical loosening and subsequent soil settlement the main factors during the season. For this study, K s was negatively correlated with bulk density, as was observed by Pöhlitz et al (2018) for different tillage systems and shown and interaction between tillage system and timestep, as was stated by Villarreal et al (2020) as a consequence of climatic fluctuations during the season. Bormann and Klaassen (2008) explained that soil water dynamics depend mainly on the physical properties of the soil, but the increase in K s would also be conditioned by the water demand of the plant.…”

“…This is in agreement with other studies, like Fuentes et al (2004), who found that saturated hydraulic conductivity in the soil was higher in NT during the period without wheat crop and decreasing once it was cultivated. Villarreal et al (2020) concluded the same, but indicate that in soils with low clay content the differences between tillage systems disappear. Alletto and Coquet (2009) found a gradual decrease of K s through time, and in general lower values in the wheel track than outside, depending on variations of coarse porosity and bulk density, as was observed by Soares et al (2020) at a large-scale approach.…”

“…As the crop grows, K ns starts recovering, first in CT which can be easily observed at the first-knot time step and then in NT, which can be seen during anthesis, where the highest values are observed in both cases. This can be explained by the natural structure regeneration through the wetting and drying cycles which restore pore continuity (Dec et al 2008;Villarreal et al 2020). Besides, the root activity of the crop increases, using more water from the first-knot timestep to anthesis because of the active growth (Fischer et al 2014), drying the soil, and favoring the assemblage of solid particles.…”

“…Hydraulic conductivity (K), both saturated and unsaturated, and their dependence on different tillage systems, had been compared with contradictory results Jonard et al 2013), because of a high variability, kind of soils, method of measurement, and sampling time during the season, among others (Lampurlanés and Cantero-Martínez 2006;Strudley et al 2008;Villarreal et al 2020). Moreover, the temporal variability is often analyzed in the long term, controlling the K value evolution over several years (Fuentes et al 2004;Pöhlitz et al 2018;Seitz et al 2019).…”

To evaluate the effect of tractor transits and tillage system operations on soil pore functioning in a Haploxeroll, soil physical properties were measured on a field located in central Chile. The study site was divided into management under no tillage (NT) and conventional tillage (CT) and a wheat-rapeseed rotation was conducted within the last 7 years. During the last wheat season, soil properties (bulk density, water content, and saturated hydraulic conductivity, K s) were evaluated at 0-5-cm depth at six timesteps (before tillage, after tillage, after sowing, first knot, anthesis, after harvest) and at two locations: in the wheel track (WT) and out of (OWT) the wheel track. The bulk density was stable in time, with values ranging between 1.18 and 1.33 Mg m −3 , expected for soil texture. The water content was in agreement with water supply and rain, decreasing sharply at the end of the season. For the saturated hydraulic conductivity, average values ranged between 0.49 and 3.08 cm h −1 , representing moderately high values. In NT, a wheel track effect was observed after sowing due to the mass of the equipment, with the lowest K s values in the NT-WT treatment (0.49 cm h −1), followed by CT in both conditions (WT and OWT). The highest K s values were observed in CT-WT at anthesis (3.08 cm h −1) as an indicator of the recovery of the soil structure. Higher variations on K s values were observed in CT than NT, with tillage × time interaction as the main factor for K s variability; in this sense, soil functioning recovers during the season has not been affected by wheel track.

“…It has been documented that the soil porous systems and associated soil physical and hydraulic properties of arable soils largely vary during the year (e.g., Alletto and Coquet, 2009;Chandrasekhar et al, 2018;Jirků et al, 2013;Nikodem et al, 2021;Schwen et al, 2011a, b;Villarreal et al, 2020). Therefore, field measurements and soil sampling were performed after harvest of wheat, i.e., on the most consolidated land.…”

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 different soil unites. Hydraulic conductivities of saturated soils and for a pressure head of –2 cm were measured directly in the field using a Guelph permeameter (K s,GP ) and mini disk tension infiltrometer (K h=– 2 ,MDI ), and in the laboratory using a multistep outflow method (K s,MSO , K h= – 2 ,MSO ). While K s,GP ≈ K s,MSO in the Chernozem and Cambisol (sandy loam) regions, and K s,GP < K s,MSO in the Luvisol and Cambisol (loam) regions. The K s values obtained using different methods showed different trends along the hillslope transects. The K h= – 2 values obtained using different methods showed similar trends along the transects in the Chernozem and Luvisol regions. These trends could be explained by the position within the transects (i.e., different stages of erosion/accumulation processes). No relationships were found between the K h=– 2 values in the Cambisol regions. The pressure head at an inflection point of the a soil-water retention curve was the main parameter, which appeared to associate (negative correlation) with K h=– 2 and K s,MSO in the Chernozem and Luvisol regions.

Temporal variation of saturated and near‐saturated soil hydraulic conductivity and water‐conducting macroporosity in a maize‐wheat rotation under conventional and conservation tillage practices

et al. 2022

Knowledge of temporal variation of soil hydraulic properties (SHPs) is crucial to understand soil physical behaviour under different tillage practices. The objective of this study was to assess the variation of saturated and near‐saturated soil hydraulic conductivity (NSHC) and water‐conducting macroporosity (Ɛ) under long‐term (09 years) tillage regimes viz. zero tillage (ZT), conventional tillage (CT), and minimum tillage (MT) in a rain‐fed maize‐wheat crop rotation (RMWC) in the North‐West Himalayas, India (NWHI). A hood infiltrometer (HI) was used to measure the steady‐state water flux (q) at 0, −10, and −30 mm pressure head (PH) after harvesting of maize and over two wheat cropping seasons for each treatment. The infiltration data were analyzed in terms of unsaturated hydraulic conductivity k(h), field saturated hydraulic conductivity (ks), water‐conducting macroporosity (Ɛ). The results showed that the seasonal effects on ks, k(h), and Ɛ values were significantly different (p ≤0.05) for tilled treatments (CT and MT). In contrast, no significant difference (p ≤0.05) was found for untilled treatment (ZT). Significantly higher (p ≤0.05) ks, k(h), and Ɛ values were observed in ZT than CT and MT, associated with higher SOC and lower ρb values. A multivariate analysis of variance of the ks showed a highly significant difference (p ≤0.01) with both time and tillage treatments. Overall, a significant improvement of hydraulic conductivity characteristics was observed during the wheat‐growing seasons compared with the maize harvest season. The temporal dynamics of SHPs under different tillage regimes indicate that ZT can be a suitable tillage practice for reducing runoff and soil loss in monsoon maize and winter wheat cropping system.
