“…Ashraf and Saeed [56] described the use the monsoon rainwater to leach the excess of soil salts after a maize (Zea mays L.)-wheat (Triticum aestivum L.)-dhaincha (Sesbania bispinosa W.Wight) crop rotation. Panagea et al [57] surveyed protected cultivation farmers' opinion to know which remedial measures for salinization are more easily to be adopted. Rainwater harvesting from greenhouse roofs was clearly the best strategy for farmers, in part because of their willingness to adopt this measure and its reduced cost.…”

A major challenge of the Sustainable Development Goals linked to Agriculture, Food Security, and Nutrition, under the current global crop production paradigm, is that increasing crop yields often have negative environmental impacts. It is therefore urgent to develop and adopt optimal soil-improving cropping systems (SICS) that can allow us to decouple these system parameters. Soil salinization is a major environmental hazard that limits agricultural potential and is closely linked to agricultural mismanagement and water resources overexploitation, especially in arid climates. Here we review literature seeking to ameliorate the negative effect of soil salinization on crop productivity and conduct a global meta-analysis of 128 paired soil quality and yield observations from 30 studies. In this regard, we compared the effectivity of different SICS that aim to cope with soil salinization across 11 countries, in order to reveal those that are the most promising. The analysis shows that besides case-specific optimization of irrigation and drainage management, combinations of soil amendments, conditioners, and residue management can contribute to significant reductions of soil salinity while significantly increasing crop yields. These results highlight that conservation agriculture can also achieve the higher yields required for upscaling and sustaining crop production.

“…Soil salinization is a major driver of land degradation, which usually goes hand in hand with accelerated soil erosion rates, agricultural mismanagement, overgrazing, mining, and deforestation (Novara et al, 2015;Seutloali & Beckedahl, 2015;Gómez-Acata et al, 2016). Salinization of soils is a consequence of both natural processes and human interference (Oo et al, 2015;Young et al, 2015;Hack-ten Broeke et al, 2016;Panagea et al, 2016). Salinity particularly affects arid and semi-arid regions.…”

Satellite Thermography for Soil Salinity Assessment of Cropped Areas in Uzbekistan

et al. 2017

A change of canopy temperature can indicate stress in vegetation. Use of canopy temperature to assess salt stress in specific plant species has been well studied in laboratory and greenhouse experiments, but its potential for use in landscape-level studies using remote sensing techniques has not yet been explored. Our study investigated the application of satellite thermography to assess soil salinity of cropped areas at the landscape level. The study region was Syrdarya Province, a salt-affected, irrigated semi-arid province of Uzbekistan planted mainly to cotton and wheat. We used moderate-resolution imaging spectroradiometer satellite images as an indicator for canopy temperature and the provincial soil salinity map as a ground truth dataset. Using analysis of variance, we examined relations among the soil salinity map and canopy temperature, normalized difference vegetation index, enhanced vegetation index, and digital elevation model. The results showed significant correlations between soil salinity and canopy temperature, but the strength of the relation varied over the year. The strongest relation was observed for cotton in September. The calculated F values were higher for canopy temperature than for the other indicators investigated. Our results suggest that satellite thermography is a valuable landscape-level approach for detecting soil salinity in areas under agricultural crops.

“…Soil salinization is one of the most serious threats for agricultural production in arid and semi regions (Qadir et al, 2008). Soil salinization is a degradation process that leads to desertification (Singh, 2015;Eskandari et al, 2016;Panagea et al, 2016;Wang et al, 2016a;Zhu, 2016). Higher salt concentrations in soil adversely affect soil physical, chemical and biological properties cause severe degradation of vegetation and soils (Singh, 2015).…”

Seasonal Patterns of Microbial Community Structure and Enzyme Activities in Coastal Saline Soils of Perennial Halophytes

Perennial halophytes are known to be one of the most influential parameters in coastal ecosystem affecting ecosystem processes. The aim of this study was to investigate the changes in soil microbial community structure and enzyme activities in different halophyte‐covered soils (Arthrocnemum indicum, Aeluropus lagopoides, Heleochloa setulosa and Suaeda nudiflora) with control soil (un‐vegetated) that were collected in three seasons (rainy, winter and summer) from intertidal coastal soils of Gujarat, India. Soil microbial community structure was assessed using phospholipid fatty acid (PLFA) profiling. Halophytes influenced significantly soil micro‐environment by exerting effects on the soil chemical characteristics, enzyme activities and microbial community structure. The activities of β‐glucosidase, urease and alkaline phosphatase were significantly higher in halophyte‐covered soils than in control soil. Among four halophyte‐covered soils, the highest amounts of total, bacterial, actinomycetes and fungal PLFAs were observed in Arthrocnemum soil. The concentrations of total, bacterial, actinomycetes and fungal PLFAs were also significantly higher in summer and winter seasons than in rainy season, whereas enzyme activities also vary with seasons. The non‐metric multidimensional scaling analysis PLFA profiling revealed that the structure of microbial community significantly differed in all seasons as well as between control and halophyte‐covered soils. These shifts in microbial community were due to the higher abundance of Gram‐positive, total bacterial and actinomycetes PLFAs in summer and winter seasons than in rainy season, whereas abundance of fungal biomarker was significantly higher in rainy season than in other seasons. Among halophytes, significantly higher abundance of Gram‐positive, Gram‐negative and total bacteria was observed in Arthrocnemum, Heleochloa and Suaeda whereas the lowest in control soil. Halophytes exhibited improved soil microbial activities, which is important for healthy ecosystem. Copyright © 2017 John Wiley & Sons, Ltd.
