Silicon fertilizer usually contains calcium, magnesium it is also called silicon calcium or calcium magnesium fertilizer. Silicon fertilizer is a new type of fertilizer; fertilizer family although its late, but it by its unique functions and is applied to the production of good results has attracted the attention of people. As early as in 1926, the United States University of California agricultural researchers began to study the silicon fertilizer and affirmed the effect of silicon. In 1935, Japan began to silicon research began in 1954, the production and application of silicon fertilizer association, founded in 1957 in Japan. Silicon has been used for more than 50 years of history in developed countries such as Japan, the Japanese government in 1955 on the silicon fertilizer method as a new type of fertilizer is determined and the large area popularization and use, a lot of silicon fertilizer has high efficiency, the use of fertilizers to Japans agriculture, farmers in Japan is considered the first silicon fertilizer. An important raw material for the production of silicon fertilizer is the industrial silicon containing waste residue and silicon contai
