“…Areas with arid and semiarid climates often have soils that are considered calcareous, which pose a problem for crop production. These soils are estimated to account for more than a third of the Earth's land surface [1]. Calcareous soil contains large quantity of calcium carbonate (CaCO 3 ) exceeds 14-17% as total CaCO 3 or 4-7% as active CaCO 3 [2].…”

Calcareous soil had sufficient phosphorus and potassium (PK) in different forms due to the high contents of PK-bearing minerals; however, the available PK state was reduced due to its PK-fixation capacity. Compost, coupled with high PK solubilization capacity microbes, is a sustainable solution for bioorganic fertilization of plants grown in calcareous soil. A 2-year field experiment was conducted to investigate the effect of compost (20 t ha−1) with Aspergillus niger through soil drenching (C-AN) along with partial substitution of PK fertilization on quinoa performance in normal and calcareous soils. Treatments included PK100% (72 kg P2O5 ha−1 + 60 kg K2O ha−1 as conventional rate), PK100%+C-AN, PK75%+C-AN, PK50%+C-AN, PK25%+C-AN, and only C-AN in normal and calcareous soils. Results showed that C-AN and reduced PK fertilization (up to 75 or 50%) increased photosynthetic pigments and promoted nutrient acquisition in quinoa grown in calcareous soil. Reduced PK fertilization to 75 or 50% plus C-AN in calcareous soil increased osmoprotectants, nonenzymatic antioxidants, and DPPH scavenging activity of quinoa’s leaves compared to the PK0%+C-AN treatment. The integrative application of high PK levels and C-AN enhanced the quinoa’s seed nutritional quality (i.e., lipids, carbohydrates, mineral contents, total phenolics, total flavonoids, half maximal inhibitory concentration, and antiradical power) in calcareous soil. At reduced PK fertilization (up to 75 or 50%), application of compost with Aspergillus niger through soil drenching increased plant dry weight by 38.7 or 53.2%, hectoliter weight by 3.0 or 2.4%, seed yield by 49.1 or 39.5%, and biological yield by 43.4 or 33.6%, respectively, compared to PK0%+C-AN in calcareous soil. The highest P-solubilizing microorganism’s population was found at PK0%+C-AN in calcareous soil, while the highest Azotobacter sp. population was observed under high PK levels + C-AN in normal soil. Our study recommends that compost with Aspergillus niger as a bioorganic fertilization treatment can partially substitute PK fertilization and boost quinoa’s tolerance to salt calcareous-affected soil.

“…High CaCO 3 of calcareous soil fixes the nutrient availability (e.g., Zn +2 , Fe +2 , Mn +2 , B, Mg +2 , P, K + , and N) affecting plant performance [9]. Thus, applying an integrated management package is essential to enhance calcareous soil quality and achieve sustainable productivity [1].…”

“…According to Edwards et al, 2019 wind erosion has serious effects for food security and therefore significant hazards to human nutrition and health & communities. In this context, the climate conditions in Sinai encourage to soil erosion by wind (Wassif 2007). In addition, the potential impacts of climate change on control of wind erosion especially vegetation cover, community composition, frequency magnitude, and erosive weather events particularly in North Sinai (Edwards et al, 2019 andSharkawy et al, 2010).…”

“…So, association between drought effect on soil erosion is quite complex (Parsons 2017 andMasroor et al, 2022). Furthermore, the effect of drought on soil reduces soil moisture and increasing soil erodibility which causes of soil degradation and/or soil desertification leading to decrease in vegetative growth (Wassif 2007 andMasroor et al, 2022). The behavior of temperature and low rainfall during drought conditions leads to wind erosion (Masroor et al, 2022).…”

Little is known about how future climate change may impact soil erosion is critical for developing appropriate management strategies, food security and significant hazards to human food and health. This study expected to have regionally variable effects in the studied area of Sinai on important how can controls of wind erosion phenomenon by using biofertilizers. Wind erosion assessed by BSNE traps. Panicum crop was cultivated on sandy soil in Baloza area, North Sinai. This study was carried out during the period from Nov.2020 to Oct. 2021. Five treatments were conducted, two added rate (15 -30 m 3 /ha) for compost added individually and combination with biofertilizers. From the results, the best treatments were 30 m 3 /ha of compost with biofertilizers which decreased annual quantity of soil loss by wind erosion about 60% as compared to control and about 42% with compared to compost individually. Also, the effect of biofertilizers substances such as Exopolysaccharide (EPS) and Fungi haiphi increased dry stable aggregate >0.84 and decrease of erodibility factor about 39% when compared with control. On the other hand, the addition of 30m 3 /ha compost with biofertilizer increased soil moisture about 97%, and reduced Enrichment Ratio (ER) of soil organic matter and total nitrogen, Phosphorus and potassium nutrients in eroded material as follow 83%,48%,62% and 57% respectively. Therefore, it significantly increased the total yield of Panicum about 70% when comparing with control. These potential biological fertilizers would play a key role in productivity and sustainability of soil and also in protecting the environment as eco-friendly and cost-effective inputs for the farmers.
