<；P>；PROBLEM TO BE SOLVED: To provide a fertilizer particle composition suitable for aerial spraying, causing less scattering outside the targeting area affected by wind in the aerial spraying by an unmanned helicopter or the like. <；P>；SOLUTION: This fertilizer particle composition for aerial spraying is characterized in that the bulk density is &ge；1.0 g/cm<；SP>；3<；/SP>；, particles passing through a sieve with 2.36 mm sieve opening are &le；10 wt.% in the whole, and the average ratio of the enveloping circumference length to the circumference length obtained from a projected image of the particle to a vertical direction with respect to a horizontal plane is &ge；0.95 in a state where the particle remains stationary at a most stable posture on the horizontal plane. <；P>；COPYRIGHT: (C)2007,JPO&INPIT
