A Review of Soil-Improving Cropping Systems for Soil Salinization

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.

“…This further suggests that quinoa can be an efficient method for desalinating soil in areas that are highly affected and can progressively pave the way for the cultivation of other salt-sensitive crops. While there is inadequate evidence available on quinoa being able to desalinate soils, other studies have already been exposed to such practice and have indeed yielded positive results [96,97]. Because of the lack of adequate information and publication in this area, more studies are encouraged to validate, ascertain, and assess the desalinating potential of different varieties of quinoa.…”

The global population is on the path of an increasing trajectory with a simultaneous decline in arable land resources through salinization and desertification that have resulted mainly from climate change and other anthropogenic activities. Rising temperatures will cause changes in the entire ecosystem, resulting in significant alterations in global climate paradigms and a threat to food security. This review focuses on how the highly resilient Chenopodium quinoa Willd. can sustainably mitigate some of the detrimental impacts, such as starvation, and support or provide ecosystem services. In comparison, compared with the traditional staple food crops, quinoa has remarkable tolerance to abiotic stresses and is highly nutritious, with a unique balance and higher amounts of nutrients, and can therefore be an important crop for food security and nutritional adequacy. This crop has the potential to ameliorate global challenges with respect to increase in global population, effects of climate change, desalinization, phytoremediation, satisfying nutrient deficiency, and alleviating poverty.

“…Table 3. Relationship of soil respiration with soil temperature, moisture, and salinity infiltration or accumulation in plant biomass were the main processes of soil desalinization [6,[22][23]. Plant roots can increase the number of bioport channels, which become preferential flow pathways for water infiltration and salt leaching [24].…”

Soil Respiration from Different Halophytic Plants in Coastal Saline-Alkali Soils

Soil salinity is a crucial constraint in the potential utilization of land resources in the coastal regions of northern China [1]. Most of the lands within these areas are covered with salinized soil and are accompanied by shallow underground water [2]. Excess salinity and alkalinity plagued seed germination and plant growth, and led to environmental degradation [3]. In order to improve these conditions, local governments have launched costal ecological restoration projects, including planting halophytes, to recover degraded vegetation and reduce soil salinization. Halophytic plants can grow well and produce high biomass in saline environments
