Salt dynamics in soil profiles during long-term evaporation under different groundwater conditions

Can subsurface soil salinity be predicted from surface spectral information? – From the perspective of structural equation modelling

“…Therefore, the indirect effects of LSSC / spec, SMC / spec and LSMC / spec were negative, while the indirect effect of SSC / spec was positive. The results of SEM were accordance with the regulation of soil salt and water transport (Liu et al, 2013) and provided detailed numerical results regarding the correlation.…”

“…Lagacherie et al (2013) mapped soil properties at four depth intervals (15e30 cm, 30e60 cm, 60e100 cm and 30e100 cm) by combining modern remote sensing techniques with historic soil databases. Shi, Aspandiar, and Oldmeadow (2014) characterized acid sulphate soil (0e100 cm depth) using hyperspectral data, and Liu et al (2013) used remote sensing data and spectral indices to estimate and simulate the three-dimensional (0e100 cm depth) spatial distribution of soil salinity. TaghizadehMehrjardi, Minasny, Sarmadian, and Malone (2014) combined regression tree analysis and equal-area smoothing splines to predict subsurface soil salinity at three depth intervals (0e15, 15e30 and 30e60 cm).…”

Restoration strategies for water and salt transport in saline soils: A 20‐year bibliometric analysis

“…The modelling approach included the use, improvement (Li et al, 2015; Liu, Ao, et al, 2021; Mao et al, 2017) and innovation (Hu et al, 2013; Xu et al, 2008) of different models applied to (a) verify its applicability (Purandara et al, 2008; Rasouli et al, 2013); (b) verify against observation results (Hammecker et al, 2012; He et al, 2017); and, (c) predict future scenarios (Jiang et al, 2011; Schoups et al, 2005). The research scale included soil column experiment (Liu et al, 2013; Xu et al, 2008), field experiment (Jiang et al, 2011; Liu et al, 2009) and regional observation (Chen et al, 2011; Schoups et al, 2005). The research content focused on the impact of climate change and anthropogenic disturbances (27.8% and 28.6%, respectively) followed by agricultural irrigation management (20%).…”

Changes in Soil Salinity and Upland Crop Productivity in Reclaimed Land as Affected by Groundwater Table

“…토양염류화는 지하수의 염농도 보다 지하수위 위치가 지표면 염류집적에 직접인 영향을 끼친다고 하였다 (Rose et al, 2005;Liu et al, 2013;Xia et al, 2016). 라이시미터 실험을 통해서 작물별 적정 지하수위 높이는 밀 (Wheat) 은 1.0 -1.5 m이고, 옥수수 (Maize)는 1.5 -2.0 m, 수수 (Sorghum)는 2.0 m이상, 해바라기 (Sunflower)는 1.5 m이하, 사탕수수 (Sugarcane)는 2.0 m이하로 작물별로 적정 지하수위는 유사하지만, 지하수위 상승에 따른 작물의 과습 민 감성은 다양하다고 보고되고 있다 (Kahlown et al, 2005;Asad et al, 2013) (Sugimori et al, 2008;Wang et al, 2008;Yang et al, 2011;Wang et al, 2011).…”
