The effects of different types of loss-controlled compound fertilizers ( the rotating-tumbling barrel-type granulated compound fertilizer amended with 4% of loss-controlled agent, the high-tower-prilling-type granulated compound fertilizer amended with 4% of loss-controlled agent, and the high-tower-prilling-type granulated loss-controlled compound fertilizer amended with 6% of loss-controlled agent) on maize were tested based on pot and field trials. The results indicated that the high-tower-prilling-type granulated loss-controlled compound fertilizers ( especially the one amended with 4% of loss-controlled agent) hare higher efficacy in enhancing growth parame-ters ( ear height, ear-generating leaf area, stem diameter, chlorophyll value, and aerial root number ) and yields, compared with 4% of loss-controlled agent. The increased economic benefit of the high-tower-prilling-type granulated loss-controlled compound fertilizer amended with 4% of loss-controlled agent reaches up to 130. 4 RMB/666. 7m2 , showing a good application prospect.
