The utilization of agricultural waste and the drying of livestock manure as a processing fertilizer have a good impact on the environment.

According to the "categories and specifications of fertilizers", if livestock manure is to be used as fertilizer, it can only be used as livestock manure composting, general composting or miscellaneous composting. Chen Junji, vice chairman of the Council of Agriculture, said in the report of the Social Welfare and Health and Environment Committee of the Legislative Yuan on the 29th that he had discussed and revised the "items and specifications of fertilizers" and added the items of fertilizers for processing livestock manure and its related regulations.

The categories and specifications of Fertilizer once stipulated that livestock manure can be used as processed fertilizer, but because the measures for the Administration of the reuse of Agricultural wastes did not open up the disposal of livestock manure other than fermentation before February this year, it has not been registered by fertilizer manufacturers for a long time, so it was deleted. Hong Hongyi, head of the Agricultural Machinery and Fertilizer Section of the Agriculture and Food Department, explains that in the past, livestock manure had to be fermented and ripened before it could be used as fertilizer.

In recent years, agricultural testing institutes have developed the technology that livestock manure can be directly dried and used as fertilizer without fermentation. In February this year, the Council of Agriculture revised the management measures for the reuse of agricultural waste, adding a way in which livestock manure can be reused after drying. Hong Hongyi said that the Agriculture and Food Administration began to review whether livestock manure processing fertilizers should be included in fertilizer categories and specifications. The schedule and other relevant details are still to be discussed by the Fertilizer Technical Consultative Council.

In addition, Chen Junji also said in his report that the Council of Agriculture rewards farmers to use domestic organic fertilizers to improve farmland fertility, not only to help remove agricultural and animal husbandry wastes and farm surplus materials, but also to improve farmland fertility at the same time. In addition to being used as fuel rods, wastes such as rice straw and rice husks can also be used in cooperation with weavers.
