Patent number: 6383247Abstract: A micronutrient-containing leaf fertilizer has magnesium sulfate heptahydrate as a carrier material in such an amount that a solid nutrient combination of 13% to 15% by weight MgO, 0% to 3.5% by weight boron, 0% to 6.5% by weight manganese and 10.3% to 14% by weight sulfur is obtained by solely admixing manganese sulfate monohydrate and boric acid with the carrier and this combination being converted into a diluted leaf fertilizer solution by adding water.Type: GrantFiled: July 2, 1999Date of Patent: May 7, 2002Assignee: Kali und Salz GmbHInventor: Bernhard Wiechens

Patent number: 6379414Abstract: A process is for the production of potash fertilizer granulates which have a stable shelf life also at high relative air humidities. This granulate contains an additive in the form of magnesium oxide and/or calcium oxide in a fine powder form, which is added by metering in prior to the compacting step. The result is a high final bursting strength even if the granulate is stored in a wet climate.Type: GrantFiled: April 27, 2000Date of Patent: April 30, 2002Assignee: Kali und Salz GmbHInventors: Ulrich Kleine-Kleffmann, Ludger Waldmann, Frank Wolf

Patent number: 6372008Abstract: An assemblage of granules including zinc sulfate heptahydrate and iron sulfate heptahydrate in a substantially integrated granular form is provided for use in e.g., the fertilizer industry. A binder, such as humate, may be used to form the granules. The granules may be dried until a slight melt is formed thereon. The granules may then be cooled to remove remaining free water. Related methods provide additional advantages.Type: GrantFiled: April 20, 1999Date of Patent: April 16, 2002Inventors: Marvin L. Boote, Bradley J. Boote

Patent number: 6365122Abstract: A new process of preparing potassium sulfate fertilizer and other metal sulfates from the chlorides and other halides of these metals. The process utilizes the discovery that sulfur dioxide or trioxide, when introduced as a fluidizing medium into shallow beds of the halide salts at moderately elevated temperatures (1000° F.-1150° F.) in a counter current process results in the conversion of the metal halides into metal sulfates and the halide gas. The process is carried out in a series of true fluidized beds preferably but not necessarily arranged in a vertical configuration so that the solids flow downward due to the fluidized process and the sulfur dioxide or trioxide gases flow counter currently in an upward direction producing pure metal sulfates at the bottom and pure halide gas at the top.Type: GrantFiled: June 22, 1998Date of Patent: April 2, 2002Inventors: William J. Rigby, Keith D. Cochran, Timothy G. Holt

Patent number: 6358294Abstract: The invention relates to free-flowing, powder fertilizer compositions characterized by having enhanced aqueous dissolution rates and being able to produce drift reduced aqueous agricultural spray medium. Specifically, the compositions are water-soluble, nitrogen-containing fertilizers physically blended with a guar gum drift reduction agent and a silicone defoaming agent either encapsulated or absorbed in an agricultural carrier.Type: GrantFiled: August 10, 1999Date of Patent: March 19, 2002Assignee: Rosen'sInventor: John Alvis Latting
