“…Hence, nine soil samples (one composite sample × three treatments × three replicates) per treatment (F, S and C) were collected, and macro-and micronutrients were analysed. Each soil sample was air-dried and sieved to < 2 mm and was analysed using the following techniques: texture by the Bouyoucos hydrometer method, pH by the potentiometric method (saturated soil paste 1:2.5), electrical conductivity, 25 N by the Kjeldahl procedure 26 and extractable phosphorous. 27 Soil samples (0.5 g dry weight) were prepared for the analysis with acid digestion in 4 mL of HNO 3 , 0.25 mL of H 2 O 2 and 2 mL of HF, as well as by applying the temperature programme in accordance with Milestones' microwave application notes (Milestone Srl, Sorisole, Italy) for microwave digestion rotor technology to determine Ca, Mg, Na and K (atomic emission); Fe, Zn, Cu and Mn (atomic absorption spectroscopy).…”

Soil erosion affects extensive areas worldwide and must be urgently reduced promoting plant cover and beneficial microorganisms associated with plants, including arbuscular mycorrhizal fungi (AMF). In mountain environments, plant cover is difficult to enhance due to harsh conditions during the dry season and steep slopes. Our objective was to evaluate the percentage of the soil surface covered by plants and the AMF community associated with trees 12.5 years after planting during forest restoration efforts in microsites at different levels of soil degradation. The study was performed in the first montane forest restoration initiative of Central Argentina, where one of the trials consisted of planting Polylepis australis saplings at microsites with different levels of soil degradation: high, intermediate, and low. After 12.5 years, percentage of bare soil cover was significantly reduced by 36 and 37% in the high and intermediate degradation microsites, respectively. Low degradation microsites were initially very low in bare soil and did not significantly change. Mycorrhizal colonization, hyphae, vesicles, arbuscules, AMF diversity, and community structure were similar among microsite types. Percentage of hyphal entry points was higher at microsites with low degradation, number of spores was higher in high and intermediate degradation, and species richness was higher in high degradation. Acaulospora and Glomus were the most abundant genera in all microsites. We conclude that even in the most degraded microsites around 2.8% of the bare soil is covered by vegetation each year and that the arbuscular mycorrhizal community is highly tolerant and adapted to soils with different disturbance types. Implications for Practice• Bare soil cover was reduced by excluding livestock and planting native trees even in the most degraded microsites (outside of erosion gullies). • The arbuscular mycorrhizal fungi community was resilient to degradation and all its species were present even in the most degraded microsites.

“…The cation exchange capacity was determined using the sodium acetate method [36]. Other ions, including Cl, Ca, Mg and HCO3, were measured using titration according to the methods illustrated by Bower [37]. Phosphorus was determined using the Olsen method [38], and total Nitrogen was determined with the Kjeldahl Salinity levels were determined according to the salinity threshold described by Maas and Hoffman [27] and the levels of water salinity that are internationally used for durum wheat salt experiments [28,29].…”

Response of the Durum Wheat Cultivar Um Qais (Triticum turgidum subsp. durum) to Salinity

The threat of land degradation by salinization in Jordan has been increasing over the last decades. Therefore, information about the response of local cultivars to salinity is needed to help farmers choose the most productive cultivars for areas with salt-affected soils. A recently released durum wheat cultivar Um Qais (Triticum turgidum subsp. durum) has shown to be productive under normal conditions but to date there are no known studies on its tolerance to salinity. Two experiments were conducted to investigate the response of Um Qais cultivar to salinity. A field experiment was carried out in the Jordan Valley, which is known for its hot, dry climate during the summer and low rainfall and moderate temperature during the winter. Three water salinity levels (S): S1 (2 dS m−1), S2 (4 dS m−1), and S3 (8 dS m−1) with three irrigation amounts (R) (control = 120% (R1), 100% (R2), and 70% (R3)) were used in the field. A greenhouse experiment was conducted using four levels of saline water (S): S1 (0.65 dS m−1), S2 (4 dS m−1), S3 (8 dS m−1), and S4 (10 dS m−1). In both experiments, the leaf area index (LAI) and canopy height were measured during three growth stages, tillering, flag leaf, and maturity. The number of grains, grain yield, and above-ground biomass were measured after harvesting while soil salinity and pH were measured every three weeks during the growing season. The results showed that the maximum reduction in yield was of the 28% in the field experiment when the average soil salinity was of 6.8 ± 1.1 (standard error) dS m−1 at the middle stages of the season. Significant changes were shown in the treatments of the field experiments for maximum LAI, number of grains, and aboveground biomass, but not for plant height. For the greenhouse treatments, about 60% of the maximum grain yield was obtained when the average soil salinity was 9.94 ± 1.89 dS m−1 at the middle stage. Grain yield was the most sensitive parameter to the increase in soil salinity during the season. According to the findings of both experiments, Um Qais can be cultivated in moderately saline soils.
