Arsenic absorption inhibitors, soil and cultivation methods

摘要

The arsenic absorption inhibitor of the present invention is an arsenic absorption inhibitor that inhibits the absorption of arsenic from the soil into the agricultural product by mixing it with the soil where the agricultural product is grown, and is a granular material containing iron as a main component and phosphorus and sulfur. , When the total content of iron is [T.Fe] mass% and the content of metallic iron is [M.Fe] mass%, the following formula (1) is satisfied. 0≤[T.Fe]-[M.Fe]≤3.5 ···(1)
