“…Significant removal of NO 3 − in applied water treatments can be related to the more intensive growth of these crops which resulted in a higher uptake of N as reported also by Vymazal [30]. Moreover, the removal of NO 3 − is an additional benefit, especially in the Spanish Southeast, since it is an area classified as a nitrate vulnerable zone in accordance with the European Union Directive [31]. The percentages of nutrient removal in these water systems were lower than in the other systems such as the soil treatment [32,33] or the biofiltration systems [34], where the percentages of nutrient removal were higher than 50%, pointing out that the results obtained in such different environmental conditions are not directly comparable.…”

Abstract:The blending of drainage with water of low electrical conductivity and the sequential reuse of the drainage water are innovative technologies to manage salts in agricultural drainage. Plants of Cucumis melo were grown in coir grow bags, and Rosmarinus officinalis and Cacti spp. were grown in pots with a mixture of sphagnum peat-moss and perlite. In order to assess the effect and evolution over time of these water treatments on plant growth and water management and removal of nutrients, three water treatments were applied over a period of eight weeks. These were: (1) standard nutrient solution; (2) blended water treatment (drainage water blended with water of low electrical conductivity (EC)) and (3) sequential reuse of drainage water treatment. During the experimental growing period, samples of water supplies and drainages generated in each water treatment were collected weekly and from these data water volume and nutrient loads were calculated. At the end of the experiment, leaf fresh weight of rosemary plants decreased under the fertigation with the blended and sequential reuse water treatments. Nevertheless, the application of blended and sequentially reused water allowed for the saving of significant amounts of water and nutrients in comparison to the standard nutrient solution treatment. Considering these advantages, we strongly recommend the setting-up of these water treatments in areas with water scarcity such as in the Mediterranean Basin.

“…In those areas, agriculture is highly dependent on water availability, which often comes from overexploited aquifers [5,6]. The overexploitation of groundwater resources has resulted in the lowering of the water levels, groundwater quality deterioration and/or seawater intrusion [7][8][9]. About 10 million hectares worldwide are abandoned every year due to soil salinization, and it is estimated that by 2050 more than 50% of arable land will potentially have serious soil quality issues [10][11][12].…”

“…For example, water and nutrient balance is negatively affected by root-zone salinity, resulting in water stress symptoms and nutrient deficiencies (e.g., tomato blossom-end rot). Nevertheless, supplying nutrients along with irrigation water, which is of a common agricultural practice (i.e., ferti-irrigation) should also take into consideration regional differences in water quality characteristics [7,15,16]. Indeed, high concentrations of soluble salts and nutrients in groundwater should be considered for optimizing fertigation management, with a special emphasis on nitrate pollution in vulnerable zones (NVZs), and on cultivation of high-value sensitive crops Similarly, high pH values may reduce micronutrient availability (e.g., iron, zinc, manganese) to crops [17].…”

This study was conducted in order to investigate possible quality changes in Cyprus’ groundwater resources over a 10-year period of pumping and to check the suitability of primary irrigation water. Water samples (n = 890) from private wells in agricultural areas were analyzed from 2009 to 2018 to determine various physicochemical properties. The sodium adsorption ratio (SAR) and residual sodium carbonate (RSC) were also calculated to evaluate potential soil degradation issues. Sodium, chloride and sulphate were found to be the predominant ions in groundwater. Quality evaluation showed possible restrictions in groundwater use for irrigation in relation to its salt content and the toxicity of specific ions having adverse effects on sensitive and several moderately sensitive crops. In particular, an increasing trend was observed in pumped groundwater for boron ion concentrations. Nevertheless, all samples evaluated were suitable for irrigation in terms of soil sodicitation and soil infiltration rate. This study indicates that in order to maintain long-term agricultural sustainability it is imperative to develop strategic plants to mitigate the adverse effects of water-pumped quality deterioration on soils and crops. Precision agriculture techniques may be adapted for better water and nutrient input/output management, thus protecting groundwater from salinization in agricultural areas. These results, among others, may be a useful tool to enhance the ability of Cyprus’s agricultural water sector to adapt to observed and anticipated climate impacts.

“…The cultivation of ornamental plants in containers on the southeast coast of Spain has increased in recent years, mainly due to the high demand from consumers [24]. Nevertheless, water supplies in this region are scarce and they have high levels of salinity [25,26], therefore an exhaustive study from an agronomic point of view concerning the ameliorative effects of variable osmolytes and the types of application in the production of ornamental species is necessary. We investigated Dracaena sanderiana Sander, a member of the family Agavaceae, known as "Lucky Bamboo".…”

Effects of Exogenous Application of Osmotic Adjustment Substances on Growth, Pigment Concentration, and Physiological Parameters of Dracaena sanderiana Sander under Different Levels of Salinity

We evaluated two osmotic adjustment substances (glycine betaine (GB) and glycine (G) and a combination of both glycine + glycine betaine (G + GB) using two modes of application; irrigation and foliar sprays with Dracaena sanderiana plants. The plants were grown in containers and subjected to two levels of NaCl concentrations (2.0 and 7.5 dS m−1) over 8 weeks. Growth, pigment concentrations, and physiological parameters were assessed at the end of the trial. The foliar application of GB resulted in most optimal plant growth and biomass production in the presence of NaCl. The chlorophyll and carotenoid concentrations showed different trends depending on the osmotic adjustment substance applied and the mode of application. Stomatal density and dimensions varied considerably with respect to the osmotic adjustment substance supplied. The concentration of soluble sugars in leaves did not show a clear trend under the different treatments assessed. The exogenous application of G resulted in the highest concentration of free proline and proteins in leaves. The antioxidant capacity in leaves increased with both osmotic adjustment substances, and both means of application, under low and high saline conditions. We concluded that the foliar application of GB can be recommended in order to achieve cost-effective growth of D. sanderiana under saline conditions.
