Abstract: Taking the plant waste as modifier of red mud, the preparation process of cultivated soil rehabilitated from red mud with wide applicability, which can treat with a large number of red mud was investigated. The basic principle of this technique was that the harmful elements in red mud are diluted by and made a complex (sequestration) process with humic acids produced by the hydrolysis and fermentation of plant waste and with the alkaline in humus and red mud so as to improve the porosity for the red mud and supply with the needs for plant growth. Good results have been achieved to prepare the cultivated soil rehabilitated from red mud by using corn stalks, bagasse and wastewater, weeds as modifier of red mud respectively in the tests, Among these, the test with corn stalks as a modifier showed that the plants grew normally in the cultivated soil with the bulk density of 1.3 g/cm³, and pH value at 7.9. 

Key words: Cultivated soil rehabilitated from red mud, Plant waste, Humification, Comprehensive utilization of red mud
