Abstract
This study was conducted to investigate the effects of the phosphogypsum on improving soil pH, increasing exchangeable calcium content, decreasing exchangeable aluminum, and supplying sulfur in volcanic ash soil on Jeju Island. The soil samples were collected from black volcanic ash soils (Wimi, Topyeong, Hangyeong, and Haengwon series), very dark brown ash soil (Jeju series) and dark brown soil (Gangjeong series). The soil ameliorants used in the culture experiment were shell meal, dolomitic limestone and phosphogypsum. The culture experiment was carried out at 25℃ for 15 days by treating soil ameliorants in 100g of soil.
The soil pH was elevated with soil ameliorants treatment. The exchangeable calcium content was the highest in the soil treated with phosphogypsum, and the total content of exchangeable cations increased with soil ameliorants treatment. The exchangeable aluminum content decreased with soil ameliorants treatment, and the exchangeable aluminum saturation was significantly decreased in the soil treated with phosphogypsum. The exchangeable sulfur content was remarkably increased in the soil treated with phosphogypsum. The ratio of the exchangeable sulfur to absorbed sulfur was measured low only in black volcanic ash soil as it contains a large amount aluminum and iron.
It is suggested that phosphogypsum can be efficiently used as a soil ameliorant to improve chemical properties in jeju soils.
