Abstract: The inorganic complex trace elements fertilizer is a new type of fritted trace element(FTE) fertilizer. The condition for preparing FTE and its forming regulation are studied in this paper. The relevant experiments indicate that the content of FTE and its technological process of production are the major factors affected the citric solubility of the fertilizer. The special effect of FTE on crops, such as grain, fruits, vegetables, are recounted. All the topics discussed in the paper would provide both theoretical and practical bases for the widespread use of FTE on growing crops.
