Latest Patents
Johanne Rødsvik holds a patent for a calcium nitrate-based fertilizer. This invention, titled "Homogeneous calcium nitrate based fertilizers containing sulphur, and method for their preparations," outlines a method where solid gypsum and/or a slow-reacting sulphate mineral is mixed with melted calcium nitrate fertilizer at a temperature of 90-110 °C. The mixture is maintained at this temperature for 3-15 minutes and subsequently particulated at a temperature of 80-110 °C. The particulation process can be performed by prilling at 95-110 °C or by granulation at 90-110 °C. The resulting fertilizer is a homogeneous composition that includes 0.1-5.0 weight % SO₂-S, 14-19 weight % water-soluble calcium, and 16-21 weight % total calcium, along with 0-3.0 weight % water-soluble magnesium. Additionally, the fertilizer may contain microamounts of selenium and/or cobalt, as well as micronutrients like manganese, copper, boron, and zinc.
