“…Palacios‐Díaz et al . [] found that the EC values accumulated in soil under subsurface drip irrigation with reclaimed municipal wastewater were above the threshold of salinity damage for alfalfa and could cause plant mortality by a 20 month field experiment. In urban green land irrigated with reclaimed water in Beijing, soil salinities were significantly higher than that irrigated with tap water or groundwater [ Pan et al ., ].…”

[1] Irrigation with reclaimed water is becoming a common practice in many cities around the word. One of the main concerns regarding the use of reclaimed water in urban green land is soil salinity accumulation. Field investigations in the seven parks of Beijing were conducted to study the accumulation of soil salinity under different reclaimed water irrigation history. The accumulation trend and distribution pattern of soil salinity in a 100 cm soil profile were evaluated by the ENVIRO-GRO model. Field investigation results showed that average soil salinity in the plots irrigated with reclaimed water was higher than that irrigated with tap water by 19.2% at the depth of 0-20 cm. Difference of average soil salinities at the depth of 0-20 cm between field measurement and model simulation was quite small, less than 15.0%. Under irrigation water salinity of 0.6, 1.2, and 2.4 dS/m, simulated annually average soil salinity decreased/increased from initial value of 1.62 dS/m, to 1.53, 2.75, and 4.66 dS/m, respectively, at the equilibrium state. Accumulation of soil salinity in clay loam was 3 times of that in sandy loam. A mild to moderate soil salinization could appear under higher irrigation water salinity, lower irrigation water amount, and heavy soil texture. Irrigation practices and soil hydraulic properties were dominated factors affecting soil salt accumulation. It is not recommended to use watersaving irrigation and irrigate on heavy soils as well as plant with a salinity stress threshold less than 1.85 dS/m under reclaimed water irrigation in Beijing.

“…All of these pollutants may transmit into soil, plants, and groundwater (Liu et al, 2005;Chen et al, 2013), imposing a threat to soil quality, human health, and food safety (Food and Drug Administration (FDA), 2001;Forslund et al, 2012). When compared to sprinkler and surface irrigation, subsurface drip irrigation can reduce human contact with effluent, the effect of drift and wetness on the irrigated crop, soil surface bacteria survival, runoff into surface waters, and odor (Lamm and Ayars, 2007;Palacios-Díaz et al, 2009;Forslund et al, 2012); therefore, it is a relatively safe way to use sewage effluent (Forslund et al, 2012;Santos et al, 2016). However, the water and nutrients for subsurface drip irrigation are easily transported to the root zone and deeper soil with the placement of a dripline beneath the soil surface (Lamm and Ayars, 2007;Li and Liu, 2011).…”

Subsurface drip irrigation is an appropriate method when using sewage effluent for crop irrigation, but its resultant heterogeneous distribution of water and nutrients in the soil may affect enzyme activities (EAs). Field experiments were designed, with three lateral depths at 0, 15, and 30 cm beneath the soil surface and three irrigation levels of 70, 100, and 130% of evapotranspiration, to investigate the effects of lateral depth, irrigation level, and water quality on the EAs of alkaline phosphatase, urease, and invertase in soil. Over 2 years, a greater lateral depth noticeably enhanced EAs in deeper soils, while EAs at a shallow lateral depth were higher in topsoil. Compared to lateral depth, the effects of irrigation level on EAs were unstable in both years. The correlations between urease activities and NO3‐N content indicated that the character of urease activities in soil N cycling was initially facilitating N mineralization and was subsequently converted to facilitate N uptake and immobilization during the maize growing seasons. Additionally, the EAs with both sewage effluent and groundwater irrigation at harvest, were generally higher than EAs measured prior to sowing. Furthermore, the sewage effluent irrigation imposed no negative effects on nutrient exchange and ecosystem functions in the soil. Our study recommends subsurface drip irrigation as a promising method for applying sewage effluent. Copyright © 2017 John Wiley & Sons, Ltd.
