【Abstract】 This paper deals with the preparation of sericite K fertilizer. Using chemical fertilizer as a standard, we have studied the fertility of sericite K fertilizer to corn and rice. The results showed that as compared with KCl, a higher concentration of intake potassium by crops and a better K supplying power of soils for sericite K fertilizer can be achieved in the same amount of potassium used. More potassium will be intaken by crops in accordance with the increase of sericite K fertilizer in soils, and readily available K and slowly available K of the residues increase, too.更多还原
