Vietnam phosphate-based manufacturers include Lam Thao Fertilizer and Chemicals JSC (capacity of 880 thousand tonnes per annum), Long Thanh Super Phosphate Company (capacity of 180 thousand tonnes per annum), Ninh Binh Phosphate Fertilizer JSC (capacity of 300 thousand tonnes per annum), and Van Dien Fused Magnesium Phosphate Company (capacity of 300 thousand tonnes); together they can almost satisfy domestic demand. Vinachem has recently started the construction of a new phosphate fertilizer (DAP) plant, with a nameplate capacity of 330,000 tpa. Sulphuric acid production will be based on MECS – U.S. technology, phosphoric acid production technology of Prayon/SNC – Lavalin, Belgium; DAP production technology of INCRO – Spain. The plant will be completed and put into operation after two years. The main feedstock will come from Lao Cai apatite ore. This is the second DAP plant of Vinachem in Vietnam, using Lao Cai apatite. The two plants will increase the domestic DAP fertilizer output to 660,000 tpa, basically meeting the domestic demand.
In Vietnam, rice production uses the highest application of fertilizers. Of the three yearly crops, that of the winter/spring season is the largest, when the use of fertilizers is always higher than during the other seasons. Geographically, the Mekong River Delta and southeastern region, accounting for 65.4 percent of total land used for agricultural production, is Vietnam’s biggest fertilizer market.
