“…This relationship is consistent with the results of Huang and Gallichand (2006) who found that the yield of apple orchards substantially depended on the dynamics of the soil-water profile after a DSL was formed in the profile. Mendham et al (2011) also reported that the productivity in the second rotation was lower than that in the first rotation, which may have been partly due to the changes in the stores of soil water in the second rotation.…”

“…7b). The amount of ANPP can reflect, to some extent, the sensitivity of plant growth to the replenishment of soil water by rainwater, because water availability is a key factor that limits the productivity of plants grown in many environments (Mendham et al, 2011). ANPP is more sensitive to replenishment by rainwater in drier soils.…”

A B S T R A C TThe natural environments in the semiarid regions of the Chinese Loess Plateau (CLP) are fragile due to the serious soil erosion and the weak ecological services of the plants. To ascertain and then evaluate a sustainable land-use pattern in these regions, we selected six typical land-use patterns (i.e., a farmland, a natural grassland, a homogeneous shrubland (S), a mix of shrubland and cultivated grassland (S-Alf), a mix of shrubland and orchard (S-O) and a mix of shrubland and grassland (S-G)) on the plateau and then measured the soil water, related soil properties and plant root indices to a depth of 1800 cm. We also measured the aboveground net primary productivities (ANPPs). The mean soil water content (SWC) within the 0-1800 cm profile was significantly highest (15.2%) in farmland, followed by grassland (11.4%) and S-Alf (8.0%). The available water (AW), the ratio between AW and AW capacity, and the thickness of the dried soil layers also demonstrated that farmland had the best conditions of soil water, followed by grassland and shrubland. The aboveground biomasses of grassland in both non-growing (140 g m À2 ) and growing (370 g m À2 ) seasons were significantly higher than those of shrublands. The ANPPs of the grassland (2.0 g m À2 d À1 ) demonstrated a similar trend. The patterns of land use (including the mixtures of different plant species) greatly affected the patterns of vertical distribution and quantities of soil water within the 1800-cm profile. The data for the soil-water regime and the ANPP further indicated that grassland would be an optimal use of the land for these semiarid regions. This information should be useful to the ecological scientists and policy makers for developing strategies for the sustainable management of vegetation on the CLP and possibly other water-limited regions around the world.

“…The most likely impacts of water repellency will occur where these plantations are harvested and regenerated, or where the plantations are returned to agriculture (i) after a biomass-producing rotation (Harper et al 2014) or (ii) where the sites are deemed unprofitable for a future plantation rotation. The high growth rates and survival of plantations established on farmland are often due to the utilisation of water stored in the soil under shallowrooted grasses or crops during the previous agricultural land use (Mendham et al 2011;Harper et al 2014). A key consideration in plantation water management is recharging the soil profile after harvest and coppicing to maximise growth in second and subsequent rotations (Mendham et al 2011).…”

“…The high growth rates and survival of plantations established on farmland are often due to the utilisation of water stored in the soil under shallowrooted grasses or crops during the previous agricultural land use (Mendham et al 2011;Harper et al 2014). A key consideration in plantation water management is recharging the soil profile after harvest and coppicing to maximise growth in second and subsequent rotations (Mendham et al 2011). Water repellency that has been induced during the first rotation will need to be managed, possibly by manipulating surface micro-topography, so that runoff is captured in localised areas and allowed to infiltrate into the subsoil.…”

Abstract. There is an increasing interest in eucalypt reforestation for a range of purposes in Australia, including pulpwood production, carbon mitigation and catchment water management. The impacts of this reforestation on soil water repellency have not been examined despite eucalypts often being associated with water repellency and water repellency having impacts on water movement across and within soils. To investigate the role of eucalypt reforestation on water repellency, and interactions with soil properties, we examined 31 sites across the south-west of Western Australia with paired plots differing only in present land use (pasture v. plantation). The incidence and severity of water repellency increased in the 5-8 years following reforestation with Eucalyptus globulus. Despite this difference in water repellency, there were no differences in soil characteristics, including soil organic carbon content or composition, between pasture and plantation soils, suggesting induction by small amounts of hydrophobic compounds from the trees. The incidence of soil water repellency was generally greater on sandy-surfaced (<10% clay content) soils; however, for these soils 72% of the pasture sites and 31% of the plantation were not water repellent, and this was independent of measured soil properties. Computer modelling revealed marked differences in the layering and packing of waxes on kaolinite and quartz surfaces, indicating the importance of interfacial interactions in the development of soil water repellency. The implications of increased water repellency for the management of eucalyptus plantations are considered.

“…At a density of 2.949 Urograndis plants per hectare, high water consumption (ET 44% greater than PPT) resembled what was observed with E.camaldulensis at a density of 2.500 plants ha -1 in India (CALDER et al, 1997), where ET was 62% greater than PPT, on average. Mendham et al (2011) reported that, because the depth of the root system of Eucalyptus globulus, there was a reduction in groundwater that would probably not be replenished in a following rotation, thus affecting the timber productivity in that site. Yin et al (2015) calculated that, among species inhabiting semi-arid environments, up to 45% of the ET comes from deep water reservoirs.…”
