ABSTRACT
Wheat is the main agricultural crop in the country side of the northern part of China. After the extraction of wheat grain, wheat husk is generated in large quantities. Wheat husk is considered to be a kind of waste material. Farmers use only a small volume of wheat husk by mixing it with the soil as fertilizer. The rest of the husk is usually burnt in the open air. Wheat husk ash (WHA) is produced as a result of the burning process. The burning in open air causes environmental problems. This is exacerbated further when the wind blows and thus transports the ash to nearby cities causing immediate health problems.Also, the farmers have to deal with this large quantity of WHA. There is a need, therefore, to properly use the WHA in order to reduce its environmental impact including land and air pollution.
