“…Hu et al () also reported that a blend of 80% Microcoleus vaginatus and 5% each of Phormidium tenue , Scytonema javanicum , Nostoc sp., and Desmococcus olivaceus was successful in increasing soil cohesion and reducing wind erosivity. Furthermore, Gheda & Ahmed () found that a mixture of Nostoc kihlmani and Anabaena cylindrica l promoted higher TOC and nitrogen than inoculation of each of them alone. In agreement with our initial hypothesis, we found that Nostoc commune and the mixture promoted better results in all soils than inoculation of Scytonema hyalinum or Tolypothrix distorta alone (Figure ), leading to greater cyanobacteria coverage and biomass, chlorophyll spectral absorption, and surface darkening, as well as TOC and TN gains in the soil (Figure ).…”

In recent years, soil inoculation with cyanobacteria has become one of the most promising biotechnological strategies for restoring soil functionality in degraded drylands because of their critical role in increasing soil fertility and preventing erosion.Nevertheless, in order to fully exploit this biotechnology on a large scale, it must still be shown whether inoculated cyanobacteria are capable of developing in soils with different physicochemical properties, and new candidates adapted to desert conditions must be explored. To evaluate the potential of cyanobacteria for restoring soil functions of degraded dryland soils, in this laboratory study, we analyzed the effect of inoculating three native N-fixing species (Nostoc commune, Scytonema hyalinum, and Tolypothrix distorta), individually and as a consortium, on soil properties from three different semiarid ecosystems in southeast Spain. The biocrust colonization was monitored by determining chlorophyll a content (the typical surrogate used for biocrust biomass). Other methodologies, such as the analysis of soil spectral response and image classification were also applied for cover estimation of the biocrust. After 3 months, all inoculated soils showed cyanobacteria cover of up to 50%, lower albedo and higher chlorophyll a content. Cyanobacterial inoculation also improved soil functions, as they promoted a significant gain in total organic carbon and total nitrogen in all soils. Among inoculation treatments, Nostoc commune and the mixture of all three species promoted the most cyanobacteria coverage, chlorophyll content, and surface darkening, as well as organic carbon and total nitrogen gains in the soil, highlighting their excellent performance in biocrust development.

“…3 Variations in amounts of N 2 fixation rates in different blue-green algae taxa were discussed in some previous studies (Moisander et al, 1996;Osman et al, 2010;Ahmed, 2015 andKhanna et al, 2016). This study pointed out that Calothrix elenkinii, Scytonema ocellatum and Westiellopsis prolifica have the highest potentials of N 2 fixation on the basis of individual unit.…”

“…To overcome this economicallyimportant problem, numerous studies on Cyanophytes particularly the heterocytous forms (Nostocales), have largely been carried out in order to characterize their highest potentialities on atmospheric N 2 -fixtion and to be widely used as natural bio-fertilizers instead of agrochemicals (Osman et al, 2010 andAhmed, 2015). During the last decades, the algal bio-fertilizers technology has been proven to be a highly applicable and a key player instead of inorganic chemical fertilizers (Maqubela et al, 2009).…”

“…During the last decades, the algal bio-fertilizers technology has been proven to be a highly applicable and a key player instead of inorganic chemical fertilizers (Maqubela et al, 2009). Furthermore, this technique is commonly avoiding soil pollution by adding chemical fertilizers affecting human health (Abdel-Raouf et al, 2012), improves the nutrients-poor soils specifically those important for seedlings germination and crops productivity (Gheda & Ahmed, 2015) and they continuously fix atmospheric nitrogen into the soil even after crop harvest (Sahu et al, 2012).…”

The experiment was run for two successive growing winter seasons during 2016-2018. The synergistic effects of Arbuscular mycorrhizal fungi (AMF) inoculation and foliar iron fertilizer on plant growth and yield parameters of broad bean plant (Vicia faba L.), grown in sandy loam soil, were conducted. Mycorrhizal colonization and their spore intensity, nodule formation and their number were also investigated. Two mycorrhizal treatments (Inoculum AMF and native AMF) and five foliar Fe-concentrations (0.0, 300, 400, 500 and 600 ppm) were applied. The interaction between different categories of AMF and foliar Fefertilization was also evaluated. The results obtained revealed that the application of inoculated AMF and spray with Fe at 400 ppm increased spore count and root colonization. However, total number of active nodules/plant increased with inoculated AMF and spraying iron at 600 ppm. Results indicated the superiority interaction treatment of inoculated AMF with the foliar Fe at the concentration of 400 ppm and/or 500 ppm by which it recorded the highest values of plant growth traits; viz, root length, number of branches/plant, total dry weight/plant and photosynthetic pigments content in both seasons. Moreover, the same treatment recorded the highest values with all pod characters and yield, except weight of number of green seeds/pod in first season and average pod weight (g) in the second one.
