Agricultural Slag Comes From Limestone and Dolomite...
Agricultural slag, or Ag-Slag, is a fine-screened material from the processing of iron blast-furnace slag, a by-product of the iron and steel industry. The slag can be watercooled, granulated, or air-cooled. Chemically, blast-furnace slag is the nonmetallic material consisting essentially of calcium and magnesium silicates and aluminosilicates. It is the direct result of adding limestone and dolomite to the blast furnace to flux or combine with the nonmetallic elements in the iron ore. Iron blast-furnace slag should not be confused with steel-furnace slag or other types of slag.
The Use of Ag-Slag is Time-Proven Ag-Slag has proven its value as an agricultural liming material since the 1920's in all types of crop production and landscaping.
• Farmers use Ag-Slag for maximum yields of cultivated crops and pasture. • Home vegetable gardeners need an easy-to-spread slag liming material. It also helps to improve soil texture, i.e., break up clay-like soil. Minor nutrient fertilization from Ag-Slag is a big attraction.
• Parks, golf courses and lawns need to correct soil acidity in order to assure optimum benefit of applied fertilizer. Ag-Slag flows easily through lawn spreaders.
• Nurseries and greenhouses use Ag-Slag is making rich soil for plant beds and potting soil.
• Land reclamation projects, e.g., coal strip mining, need a liming material to neutralize high soil acidity.
