“…While stony soils have been studied in the past using HYDRUS (2D/3D) (e.g., Hlaváčiková et al, 2016;Novák et al, 2011;Parajuli et al, 2017), those studies considered only hypothetical soil systems with simplified geometries and idealized distributions of stones. Hlaváčiková et al (this issue) in this issue used HYDRUS-1D to assess the impact of stones in real soils of the High Tatras mountains in Slovakia on soil water storage and recharge.…”

“…Another approach is to estimate hydrophysical characteristics of stony soils by numerical modeling. Novák et al (2011) were the first who used the HYDRUS-2D model in the numerical Darcy experiment. The same approach was later applied by Hlaváčiková et al (2016) and Beckers et al (2016).…”

“…The same approach was later applied by Hlaváčiková et al (2016) and Beckers et al (2016). These studies examined the role of stoniness, the size of RF (Novák et al, 2011), and the shape, distribution, and position of RF in the stony soil on saturated (Hlaváčiková et al, 2016) and unsaturated hydraulic conductivities (Beckers et al, 2016).…”

Stony soils are composed of two fractions (rock fragments and fine soil) with different hydrophysical characteristics. Although stony soils are abundant in many catchments, their properties are still not well understood. This manuscript presents an application of the simple methodology for deriving water retention properties of stony soils, taking into account a correction for the soil stoniness. Variations in the water retention of the fine soil fraction and its impact on both the soil water storage and the bottom boundary fluxes are studied as well. The deterministic water flow model HYDRUS-1D is used in the study. The results indicate that the presence of rock fragments in a moderate-to-high stony soil can decrease the soil water storage by 23% or more and affect the soil water dynamics. Simulated bottom fluxes increased or decreased faster, and their maxima during the wet period were larger in the stony soil compared to the non-stony one.

a b s t r a c tThe proportion of rock fragments in soil affects water availability and therefore the characteristics of plants. The objective of this study was to evaluate the effect of rock-fragment content on plant water consumption, biomass, growth and water-use efficiency (WUE) under different water conditions. Four gravimetric treatments of rock-fragment contents (0, 10, 30 and 50%) and four treatments of water content were tested in sandy loamy soils. The water contents of the rock-free soil were 15-19% (80-100% of field capacity), 11-15% (60-80% of field capacity), 9-11% (47-60% of field capacity) and 6-9% (32-47% of field capacity). Transpiration, plant height, basal stem diameter and biomass of korshinsk peashrubs in the treatments were measured and compared. Plants grown in the soil with rock fragments transpired less, especially under well-watered conditions. The mean daily transpiration of plants in the soils with 30 and 50% rock-fragment contents was 18% (P = 0.021) and 34% (P = 0.001) lower, respectively, in 2014, and 25% (P = 0.008) and 31% (P = 0.002) lower, respectively, in 2015 relative to the soil without rock fragments and was not lower in the soil with 10% rock fragments. Plant height, basal stem diameter and biomass did not differ significantly between rock-fragment contents of 0 and 30% but were lower at 50%. WUE, the ratio between total transpiration and biomass, was highest at 30% and then decreased at 50%. Increasing plant water stress could thus improve WUE. The rock fragments in the soil had significant effects on plant water consumption, biomass, growth and WUE. Optimizing the rock-fragment content is necessary when the relationships between plants and water in stony ecosystems are evaluated.
