Abstract :
    Two thirds of Iran s land is located in dry and semi-arid climate, with over 45 million hectares being deserts. One of the most important factors affecting these areas is soil wind erosion. The problem that has arisen in recent years in Iran and some of the neighboring countries is the dust that the use of petroleum chemicals has always been an issue for solving this environmental problem, but because of the high price and controversy, the recently proposed biological methods So that they can help solve this environmental problem with higher efficiency. This new method for the stabilization of fine particulate matter is the production of microbial calcium carbonate (MICP) in the soil surface, which is also referred to as a mulch bio. In this method, the bacteria cultured in the laboratory and the solution of cementation including urea and calcium chloride and their injection into soil samples, the formation of calcium carbonate (caco3), is formed in the soil, causing the soil to adhere to each other. It will eventually lead to soil stabilization. This method is environmentally friendly and does not produce environmental impacts, such as eating ecosystems, compared to mulches.
