PROBLEM TO BE SOLVED: To provide iron powder for coating seeds which scarcely falls off not only during sowing but also during transportation and enables coating with less variation in seeds, and iron powder-coated seeds that are coated with the iron powder for coating seeds.SOLUTION: In the iron powder for coating seeds, that is iron powder used for coating seeds, the ratio by mass of iron particles having a particle size of 63 μm or smaller is controlled to 0-75%, the ratio by mass of iron particles having a particle size larger than 63 μm but not larger than 150 μm is controlled to 25-100%, the ratio by mass of iron particles having a particle size larger than 150 μm is controlled to 0-50%, and the content ratio of metal iron is 30.0-99.0 mass%.COPYRIGHT: (C)2013,JPO&INPIT【課題】播種工程のみならず輸送工程においても鉄粉の脱落が少なく、また種子間のばらつきも少なく被覆が実現できる種子被覆用鉄粉及び該種子被覆用鉄粉を被覆した鉄粉被覆種子を得る。【解決手段】本発明に係る種子被覆用鉄粉は、種子を被覆するのに用いる鉄粉であって、粒子径が63μm以下の鉄粉の質量比率が0%以上75%以下、かつ、粒子径が63μmを越え150μm以下の鉄粉の質量比率が25%以上100%以下、かつ粒子径が150μmを越える鉄粉の質量比率が0%以上50%以下であり、かつ金属鉄の含有比率が30.0質量%以上99.0質量%以下であることを特徴とするものである。【選択図】 図1
