#0183;#32;In Japan, steel slag fertilizer was used in a damaged paddy field located near the lower reaches of the Kitakami River where the seawater flowed into the river after the tsunami. Steel slag fertilizer was applied at a rate of 200 and 400 g m 2, which led to an increased yield of about 8% for the rice planted compared with the rice planted
Steel slag phosphate fertilizer was made from basic steel slag by crushing and grinding. Its main components were Ca 4 (PO 4) 2, Ca 2 SiO 4, and some metal elements such as magnesium, iron, and manganese. For acid soil, steel slag phosphate fertilizer was an excellent base fertilizer, which could improve soil fertility.
