“…Their results were similar to ours showing that shoot N did not change or slightly increased as salinity increased, although they did not test K doses. A stable or increased shoot N concentration was also previously reported for Jerusalem artichoke (Helianthus tuberosum L.) and alfalfa (Medicago sativa L.) cultivated in sand and with waters of increased salinity [33,34]. Regarding P, all our plants accumulated P at 4.8 to 6.7 g kg −1 ('Raccoon') and at 3.9 to 5.7 g kg −1 ('Gazelle') ( Figure 3b,h), above adequate for growth [35] and slightly under concentrations (7.7 to 10 g kg −1 ) reported for hydroponic spinach [31] and slightly above shoot-P concentrations for spinach irrigated with similar salinity treatments combined with five N doses [32].…”

“…Shoot concentration of Ca decreased significantly with salinity for both cultivars, regardless of K dose. Ca decreased between control (5 mmol c L −1 ) and the highest salinity (120 mmol c L −1 ) treatment by 33.3% (at 0.25 K) and by 45.5% (at 5.0 K) in 'Raccoon' (Figure 3d) and by 45.5% (0.25 K) and 49% (5.0 K) in 'Gazelle' (Figure 3j). While Mg decreased significantly for both cultivars when K increased from 0.25 K to 5.0 K, regardless of salinity, Mg remained fairly constant across salinity for both cultivars, averaging 0.55 mol kg −1 (13.5 g kg −1 ) for 'Raccoon' and 0.46 mol kg −1 (11.25 g kg −1 ) for 'Gazelle' at 0.25 K, but leaf concentrations reduced significantly with K = 5.0 mmol c L −1 in approximately 0.08-0.24 mol kg −1 (2.0-6.0 g kg −1 ) for both 'Raccoon' and 'Gazelle' (Figure 3e,k).…”

Two spinach (Spinacea oleracea L.) cultivars were evaluated for their response to deficient (0.25 mmol c L −1 or 0.25 K) and sufficient (5.0 mmol c L −1 or 5.0 K) potassium (K) levels combined with salinities of 5, 30, 60, 90, and 120 mmol c L −1 NaCl. Plants substituted K for Na proportionally with salinity within each K dose. Plants favored K + over Na + , regardless of salinity, accumulating significantly less Na at 5.0 K than at 0.25 K. Salinity had no effect on N, P, and K shoot accumulation, suggesting that spinach plants can maintain NPK homeostasis even at low soil K. Ca and Mg decreased with salinity, but plants showed no deficiency. There was no Na + to K + or Cl − to NO 3 − competition, and shoot biomass decrease was attributed to excessive NaCl accumulation. Overall, 'Raccoon' and 'Gazelle' biomasses were similar regardless of K dose but 'Raccoon' outproduced 'Gazelle' at 5.0 K at the two highest salinity levels, indicating that 'Raccoon' may outperform 'Gazelle' at higher NaCl concentrations. At low K, Na may be required by 'Raccoon', but not 'Gazelle'. This study suggested that spinach can be cultivated with recycled waters of moderate salinity, and less potassium than recommended, leading to savings on crop input and decreasing crop environmental footprint.

“…Modification of micro climate using mulch at saline soil was another way to reduce salinity negatif effect on plant growth (Kusmiyati et al, 2016). Other approach of using saline soil as agricultural land is utilizing salt tolerance plant (Rui-dong, 2018 andDiaz et al, 2018). Ahmad et al (2010) stated that reduction of photosynthetic capacity was lower at salttolerant populations compared to salt-sensitive populations.…”

The objective of this study was to evaluate the effect of manure at saline soil on forage production, quality and livestock carrying capacity of P. maximum and S. grandiflora. The research was conducted on moderately saline soil at Rembang Regency, Central Java Province, Indonesia.Randomized complete block design was used as design experiment. The treatments were different dosage of manure as organic amendment (0, 10 and 20 tonnes/ha). Forage crops were P. maximum and S. grandiflora that planted monoculture or mixed-cropping. Parameters measured were dry matter (DM) production, ash, crude protein, crude fibre, ether extract, total digestible nutrients. P. maximum was cut eight times, S. grandiflora was cut six times during one year. The result showed that the highest total dry matter production of mixed cropping P. maximum and S. grandiflora was available at moderately saline soil with application 20 ton/ha manure. Total production of dry matter, crude protein and total digestible nutrient available at application 20 ton/ha manure were 29131 kg/ha/year; 3722 kg/ha/year and 17718 kg/ha/year, respectively. Carrying capacity based on dry matter, crude protein and total digestible nutrients were 10.8 AU/ha/year; 13.6 AU/ha/year and 11.3 AU/ha/year, respectively. In conclusion, application of 20 ton/ha manure at saline soil increased production, crude protein and carrying capacity.

“…In order to preserve agricultural soils and crop production potential, the application of management techniques able to reduce soil salinity or prevent the continuous accumulation of salts in the soil root layer is required [17]. Leaching, namely the movement of excess soluble salts from the upper to the lower soil depths or out of the root zone due to draining water, is the key operation to control salinity.…”

Mediterranean climate is marked by arid climate conditions in summer, therefore, crop irrigation is crucial to sustain plant growth and productivity in this season. If groundwater is utilized for irrigation, an impressive water pumping is needed to satisfy crop water requirements at catchment scale. Consequently, irrigation water quality gets worse, specifically considering groundwater salinization near the coastal areas due to seawater intrusion, also triggering soil salinization. With reference to an agricultural coastal area in the Mediterranean basin (Southern Italy), close to the Adriatic sea, an assessment of soil salinization risk due to processing tomato cultivation was carried out. A simulation model was arranged to perform, on daily basis, a water and salt balance along the soil profile. Long-term weather data and soil physical parameters representative of the considered area were utilized in applying the model, also considering three salinity levels of irrigation water. Based on the climatic analysis performed and the model outputs, the probability of soil salinity came out very high, such as to seriously threaten tomato yield. Autumn-winter rainfall resulted frequently insufficient to leach excess salts away from the soil profile and reach sustainable conditions of tomato cultivation. Therefore, alternative cropping strategies were prospected.
