“…Due to the large macroporosity of litter, depending on the size of organic particles in its composition (Ilek et al 2017), water retention in this horizon occurs mainly through the adsorption and absorption of water through undecomposed organic matter. Zhang et al (2006) found that the rate of water absorption by undecomposed litter of various types of stands decreases rapidly in the first 6 hours of soaking; and in the first 8 hours in the case of partially decomposed litter. In both cases, most of the water was absorbed in the initial period of soaking, and the influence of the type of stand on the absorption rate was hardly noticeable.…”

“…Litter plays an important role in water infiltration into the soil profile, prevents erosion, slows down stemflow and limits evaporation from deeper soil horizons (Onda & Yukawa 1994, Tamai et al 1998, Greiffenhagen et al 2006). Its water storage capacity depends not only on the quantitative share of individual litter components, such as leaves, needles and branches, but also on the bulk density, total porosity and species composition of the stand (Laurén & Mannerkoski 2001, Zhang et al 2006, 2009, Ilek et al 2015.…”

The water absorbability of beech (Fagus sylvatica l.) and fir (Abies alba mill.) organic matter in the forest floor

The organic horizons of forest soils are characterised by double capillarity: between particles and inside them. It has been hypothesized that the time required to fill the internal capillarity of organic particles depends on their botanical origin and the degree of their decomposition. The aim of the present study is to determine the time of water absorption by organic matter that is part of the Ol and Ofh horizons of selected beech (Fagus sylvatica L.) and fir (Abies alba Mill.) stands. The present research on water absorbability lasted for 14 days and consisted in measuring the absorption time in organic particles from the moment of immersion of an air-dry sample in water until the particles soaked in water exceeded the density of 1.0 g•cm -3 . It was found that in fir organic matter the time of water absorption decreases with the advancement of decomposition. In beech stands, progressing decomposition processes result in a longer water absorption time. The dynamics of water absorption of organic matter indicates that no single rainfall is able to entirely fill the internal capillarity of organic particles, whereby the organic horizons of forest soils can maintain the ability to retain water even in long-term rainfall.

“…6). Similarly, Zhang et al (2006) showed that the water storage capacity of the litter of coniferous stands is greater than that of deciduous ones. Leuschner (1998) showed differences in the formation of the water storage capacity of organic horizons between beech, oak and pine stands.…”

“…The water storage capacity of the organic horizons of forest soils is affected by a number of factors, such as the type and degree of decomposition of organic matter (Zhang et al 2006;Kucza 2007;Tsiko et al 2012) and the wettability of the soil material (Prusinkiewicz and Kosakowski 1986). Putuhena and Cordery (1996), Sato et al (2004) and Li et al (2013) found that the water content of the forest litter has a linear relationship with respect to its mass.…”

The effect of stand species composition on water storage capacity of the organic layers of forest soils

The dynamics of litterfall and its quantitative differentiation in stands with different species composition suggest that the origin of the organic matter accumulated in the organic horizons of forest soils affects their physical properties, and thus, their ability to retain rainwater. The main aim of the study was to determine the physical properties, the degree of decomposition and capillary capacity of individual ectohumus sublevels of mountain forest soils, formed under fir stands (Abies alba Mill.) and beech stands (Fagus sylvatica L.), and to compare them with the physical and retention properties of the organic horizons of spruce stands [Picea abies (L.) H. Karst], as determined by Kucza (2007). The study was conducted on soil monoliths, sampled in a way that allowed preserving their natural structure. For individual ectohumus sublevels contained in the monoliths, the content and degree of decomposition of organic matter, bulk density, total porosity and capillary capacity were determined. It has been shown that the capillary capacity of the litter layer (Ol) differed significantly between beech, fir and spruce stands, assuming average values equal to 1.60 (±0.10), 2.76 (±0.11) and 4.44 (±0.10) mm H 2 O in the layer of 1 cm, respectively. In the case of detritus (Ofh) horizons, the smallest water storage capacity characterized beech stands, wherein the capillary capacity was approximately 1.39 mm lower than in fir stands and over twice lower as compared to spruce stands.

“…In turn, this probably resulted in a reduction of the litter water storage capacity and degree of saturation, despite the slight impact of pine needle admixture on changes in bulk density of the litter and its porosity (compared to pure oak litter). Some studies indicated that mixed litter had a higher water storage capacity than pure coniferous litter [33], but mixed coniferous-broadleaved litter usually showed a lower water storage capacity than mixed coniferous litter [55,56]. Mixed stands also influence other properties of the litter.…”

During the last decade, tree species mixing has been widely supported as a silvicultural approach to reduce drought stress. However, little is known on the influence of tree species mixing on physical properties and the water storage capacity of forest soils (including the forest floor). Thus, the study aimed to analyze the effect of mixing pine needles and oak leaves and mixing fir needles and beech leaves on hydro-physical properties of the litter layer during laboratory tests. We used fir-beech and pine-oak litter containing various shares of conifer needles (i.e., 0, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) to determine the influence of the needle admixture on bulk density, total porosity, macroporosity, water storage capacity, the amount of water stored in pores between organic debris and the degree of saturation of mixed litter compared to broadleaf litter (oak or beech). We found that the admixture of fir needles increased the bulk density of litter from 7.9% with a 5% share of needles to 55.5% with a 50% share (compared to pure beech litter), while the share of pine needles < 40% caused a decrease in bulk density by an average of 3.0–11.0% (compared to pure oak litter). Pine needles decreased the water storage capacity of litter by about 13–14% with the share of needles up to 10% and on average by 28% with the 40 and 50% shares of pine needles in the litter layer. Both conifer admixtures reduced the amount of water stored in the pores between organic debris (pine needles more than fir needles).
