| ABSTRACT 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 m3/ha) for compost added individually and combination with biofertilizers. From the results, the best treatments were 30 m3/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 30m3/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. | ||
