“…Although Na + is easily leached in wet environments, soils derived from igneous rocks, like basalt, have residual amounts of Na + released by weathering (Segalen, 1971), which may explain the level of Na + even in the control soil when sampled in a dry period. Similarly, Glenn et al (2009) also showed an increase in Na + at the surface of a soil that received Na + –rich wastewater when the irrigation level was kept below the potential evapotranspiration. In the present work, Na + concentrations in the soil ranged from near zero up to 1.2 cmol kg −1 , showing that concentrations throughout the soil profile depend on the rainfall affecting Na + concentrations in the leachate (Loncnar et al, 2010) and its movement through the soil after application (Gloaguen et al, 2007).…”

Landfill leachates are pollutants rich in ammoniacal N, Na, and K, but land application potentially offers an alternative for recycling these leachate nutrients. We applied landfill leachate corresponding to 0, 110, 220, 330, and 440 kg ha of total N, divided in three applications (July, August, and October 2008), onto the surface of an acidic (pH 5.5-6.0) clay (79% clay) Ultisol and monitored NH volatilization just after applications and microbiological (0-10 cm) and chemical attributes (0-60-cm soil depth) in August 2008, January 2009, and May 2009. Ammonium (up to 30 mg kg), NO (up to 160 mg kg), Na, K (up to 1.1 cmol kg each), and electrical conductivity (up to 1 dS m) increased transiently in soil following applications. Despite >90% of the total leachate N being ammoniacal, NO predominated in the first soil sampling, 14 d after the second application, suggesting fast nitrification, but it decreased in the soil profile thereafter. From 5 to 25% of the total applied N volatilized as NH, with maximum losses within the first 3 d. Applications inhibited (50%) the relative nitrification rate and increased (50%) hot-water-soluble carbohydrates in the soil at the highest rate. No effects were observed on soil microbial biomass C (114-205 mg kg) and activity (5-8 mg CO-C kg d) or on corn grain yields (6349-7233 kg ha). Controlled land application seems to be a viable alternative for landfill leachate management, but NO leaching, NH volatilization, and accumulation of salinizing ions must be monitored in the long term to prevent environmental degradation.

“…Some of these halophytes are thought to be native to rare inland salt springs (Reznicek 1980), thus human activities have unwittingly expanded the habitat available for native species and decreased the rarity of particular species associations in the region. This phenomenon has direct applications to urban ecosystems, as halophytes can be used to treat saline waste waters in arid zones (Glenn et al 2009). The prevailing view suggests that salted motorways are completely novel environments (Kowarik 1990), but the habitat analogue perspective suggests that halophytes colonizing these areas are not exploiting novelty but rather responding to conditions resembling those under which they evolved.…”

Summary1. Current views of anthropogenic environments emphasize the extreme novelty of urban and industrial ecosystems. Proponents of reconciliation ecology argue that we need to use such habitats to conserve biodiversity, given the inadequacy of natural reserve systems. 2. Some of the harshest anthropogenic ecosystems may be able to support indigenous biodiversity due to their structural or functional resemblance to natural ecosystems, habitats, or microsites that may be present in the region but not part of the historic ecosystem on a particular site. Here we review recent work that evaluates similarities between urban and industrial ecosystems and natural analogues, and explore the potential for these in reconciliation ecology. 3. We find that artificial habitats represent a gradient of ecological novelty which may be independent of the degree of human influence. While hard-surfaced habitats such as walls and quarries are the most investigated artificial analogues (of natural rock pavements and cliffs), there are many other examples spanning a range of habitats in both terrestrial and marine settings. Analogous ecosystems may be present in the region but limits to dispersal can prevent appropriate species from reaching urban or industrial sites, and small differences in abiotic conditions can sometimes prevent colonization by native biota in otherwise similar artificial habitats. We suggest that a search for habitat analogues represents an important principle to guide reconciliation ecology in urban and industrial lands. In constrast, analogous ecosystems may also support pest species that exploit the similarities between anthropogenic habitats and their ancestral habitats. 4. Synthesis and applications. Identifying analogous habitats and ecosystems could enhance biodiversity conservation and ecosystem services in anthropogenic environments. Abiotic and biotic differences between artificial analogues and natural systems can be frequently overcome by ecological engineering to make the environment more suitable for native biodiversity, and ⁄ or assisted dispersal to allow suitable native organisms to reach appropriate sites within artificial ecosystems. Altering some habitats to become less analogous may help reduce impacts of pest species in urban and industrial areas.

“…Soil water content (or soil moisture content, SMC) assessment is critical in agriculture, hydrology, micrometeorology, defense, civil engineering, and other environmental fields (e.g., Gardner, 2000;Robinson et al, 2008;Vereecken et al, 2008;Wang and Qu, 2009;Ochsner et al, 2013). In agriculture, SMC is an indicator of soil sensitivity to wind erosion; it also provides information about water infiltration, runoff and storage that helps monitor soil-water-plant conditions and manage irrigation (Glenn et al, 2009;Yang et al, 2012). Therefore, it is highly correlated with crop yield estimation.…”
