Title:
IRON POWDER FOR COATING SEEDS, AND SEEDS
Document Type and Number:
WIPO Patent Application WO/2012/029969
Kind Code:
A1
Abstract:
In an iron powder for coating seeds, the ratio by mass of iron particles having a particle diameter of 63 μm or smaller is controlled to 0-75% inclusive, the ratio by mass of iron particles having a particle diameter larger than 63 μm but not larger than 150 μm is controlled to 25-100% inclusive, and the ratio by mass of iron particles having a particle diameter larger than 150 μm is controlled to 0-50% inclusive. Thus, an iron powder for coating seeds, when used in coating, said iron powder scarcely falling off not only during sowing but also during transportation, and iron powder-coated rice seeds that are coated with the iron powder for coating seeds can be obtained. Moreover, an iron powder for coating rice seeds, said iron powder unlikely damaging rice seeds and being easily handled, and iron powder-coated rice seeds that are coated with the iron powder for coating rice seeds can be obtained.
