Abstract Mulch can be called a soft cover that is used naturally and artificially for purposes such as stabilizing sand and loamy and fine-grained soils in desert lands. Conventional methods for reducing dust storms in hot, dry and semi-dry logic have been the stabilization of the dust generating center using chemical polymers and petroleum products called synthetic mulches, which can not be used with existing conditions, high costs and environmental problems.In this dissertation, the eva‎luation and research of bio-mulching behavior with starch base was investigated to stabilize fine dust in laboratory conditions and also to determine the optimal result in soil. Bio-mulching was performed using natural and biodegradable compounds of starch, flour, bran and dry bread and rice waste. The mentioned bio-mulch gels were placed in water during two stages of mixing and filtration. The gel produced from each was sprayed on a surface of sandy soil.Wind, resistance, wind, viscosity, pH, density, soil penetration, water absorption, biodegradability, environmental compatibility, restoration, paint, freezing point tests were performed. The results showed that mulch prepared from dry bread and rice waste is the best option for mulching and controlling fine dust in every respect.
