PROBLEM TO BE SOLVED: To provide seed-coating iron powder capable of realizing the coating of little dropout of the iron powder even at not only a dissemination step but also a transportation step, an iron powder coated seed coated with the seed-coating iron powder, rice seed coating iron powder little possible of giving a damage to a rice seed and easily handled, and an iron powder coated rice seed coated with the rice seed covering iron powder.SOLUTION: Seed-coating iron powder is used for coating a seed, the mass ratio of the iron powder with a particle diameter of 45 μm or less is more than 35% and less than 85%, the mass ratio of the iron powder with a particle diameter of 63 μm or less is more than 75%, and the content ratio of metal iron is 30.0 mass% or more and 99.0 mass% or less.SELECTED DRAWING: Figure 1 |
