Research Abstract

The plow layer soil of paddy field is reduced after transplant of rice seedlings and submergence. Under the reducing conditions, a part of phosphate in the plow layer soil crystalized as vivianite. A quantitative method to estimate the content vivianite was developed using the fact that vivianite is converted to a sparingly soluble material in the dilute acid with heating. Vivianite formation is more common in lowland soils such as gley lowland soils and gray lowland soils than in volcanic ash soils. The vivianite content decreased during midseason drainage and after drainage when the plow layer soil is oxidized.
