摘要
The present invention relates to a method for producing a slow-release matrix-type granular composite fertilizer having improved a utilization rate and a matrix-type granular composite fertilizer obtained from the same. The method according to the present invention comprises the steps of: producing an additive having a nutrition absorbing function by mixing, drying, and pulverizing a natural or synthetic polymer as a binder and an extender having a nutrition absorbing function; and producing a matrix-type granular composite fertilizer by uniformly mixing and drying the additive having the nutrition absorbing function with a fertilizer ingredient.
