Patent number: 7155377Abstract: The present invention is a system and method for accurately calculating the spatial-temporal effects of a variety of environmental conditions on animal individual, population and community dynamics, given the animal's temperature-dependent behaviors, morphology and physiology, by running integrated microclimate and animal models to calculate the discretionary energy and water available to the animal and its activity time. The methodology requires relatively few, easily measured data to perform the calculations. The microclimate model translates a set of climate and other environmental conditions into a set of microclimate conditions experienced by an animal, given a set of the animal's characteristics. The animal model uses the microclimate conditions data and the set of animal characteristics data to solve for several animal conditions. Further calculations and several display options are available to a user, including spatial-temporal analyses.Type: GrantFiled: August 23, 2001Date of Patent: December 26, 2006Assignee: Wisconsin Alumni Research FoundationInventors: Warren P.

The process comprises initially mixing and conditioning the raw organic biosolid waste material to a substantially uniform size, oxidizing the raw organic biosolid waste material, secondarily mixing the oxidized and transformed organic biosolid waste material, drying the oxidized and regenerated organic biosolid waste material thereby completing the resource regeneration process for creating an organic biomeal nutrient-rich product from raw biosolid waste material wherein the resource regeneration process is completed within a time range of approximately twenty (20) minutes to approximately thirty (30) minutes.Type: GrantFiled: June 20, 2002Date of Patent: February 11, 2003Inventor: R. Gene Gilbert

Patent number: 6503287Abstract: A soil distribution system, and particularly a method of blowing topsoil, using an improved topsoil blend and specialized equipment, onto selected surfaces, including sloped surfaces. The topsoil blend may be placed either via traditional or selected placement means including placement by blowing the mixture into place. The topsoil blend may be blown through a manipulatable distribution line onto the surface, including areas which may be substantially inaccessible. A selected aerobic compost tea may be combined with the soil distribution operations such that the tea is distributed and intermixed with the soil as the soil is blown into place. Greensand may be distributed over the surface prior to blowing the soil in place and the soil is then distributed over the layer of greensand.Type: GrantFiled: April 7, 2000Date of Patent: January 7, 2003Inventor: Hendrikus Schraven

Patent number: 6464875Abstract: A system and method for converting animal, vegetable, and food byproduct materials into useful bio-gas and fertilizer, and/or soil amendment products has an anaerobic digester, a liquid-solids separating unit, an ammonia stripper, an ammonia absorption unit, a solids processing unit, and an equilization tank. The system and method use anaerobic digestion to break down the fats, oils, and greases, proteinaceous, and carbonaceous substances contained in the byproducts. Anaerobic digestion creates bio-gas, mainly methane and carbon dioxide, waste biosolids, which can contain phosphorous, nitrogen and other trace minerals, and a liquid effluent with significant ammonia levels. Ammonia, a useful ingredient for fertilizer formulation, is recovered from the effluent. The solids and the extracted ammonia and/or phosphorous can also be used to make fertilizer and/or soil amendment materials.Type: GrantFiled: April 21, 2000Date of Patent: October 15, 2002Assignee: Gold Kist, Inc.Inventor: Steven R. Woodruff

Patent number: 6419722Abstract: A process for making an artificial soil includes first combining the volume percentages of the following substances: 1-99% materials suitable for use as a blending base; 1-99% cellulose; 0.01-60% bio-solids; 0.01-10% calcium in any form; 0.01-10% charcoal or it's equivalents; and 0.05-5% ammonium nitrate, ammonium sulfate, or calcium nitrate. The above substances are ground until a homogeneous mixture is obtained, after which the artificial soil can be either blended in place or manufactured at one location and transported to another location for use.Type: GrantFiled: September 28, 2001Date of Patent: July 16, 2002Inventor: Paul Thomas Adam

Patent number: 6413291Abstract: Mechanically strong, water-disintegrable agglomerates made from a particulate calcium source, a water-soluble binder and optionally containing a primary plant nutrient source and/or micronutrient source and a process for forming such agglomerates are disclosed. The agglomerates may be used as a soil liming agent and for introducing nutrient values into cultivated soil. Also disclosed is a method for introducing nutrient values into cultivated soil so as to inhibit leaching of the nutrient values from the soil and improve utilization of the nutrient values by plants grown in the soil.Type: GrantFiled: November 28, 2000Date of Patent: July 2, 2002Assignee: Magic Green CorporationInventors: Greg Wommack, Roy M. Stephen
