  • Patent number: 5976210
    Abstract: A granular fertilizer which provides plant assimilatable nutrients by both hydrolysis and bacterial activity, and which includes biological growth promoting nutrients. The fertilizer is made by blending and pelletizing an aggregate of conventional fertilizing materials, biological food source materials and at least one hydrophilic material which expands upon wetting and becomes porous and wick-like upon heating to drive off absorbed water. In its dry state, the hydrophilic material wicks up applied liquid biological inoculum which remains dormant until dispensed and exposed to adequate heat and moisture.

  • Patent number: 5912398
    Abstract: A composition is disclosed for providing phosphate fertilizer to the root zone of plants. The composition comprises a microorganism capable of producing and secreting a solubilization agent, a carbon source for providing raw material for the microorganism to convert into the solubilization agent, and rock phosphate ore for providing a source of insoluble phosphate that is solubilized by the solubilization agent and released as soluble phosphate. The composition is provided in a physical form, such as a granule, that retains the microorganism, carbon source, and rock phosphate ore, but permits water and soluble phosphate to diffuse into the soil. A method of using the composition for providing phosphate fertilizer to plants is also disclosed.

  • Patent number: 5772721
    Abstract: A substantially odorless and sterilized fertilizer in pellet form is produced by combining a dry organic waste material and a dry binder material, then combining the resulting dry mixture with steam, water and/or further organic waste in the form of sludge. The resulting material is provided to an extruder for a more thorough, dispersive mixing, a pressure increase to at least 100 psi, and heating above the glass transition temperature of the binder, and more preferably to at least about 125.degree. C. to substantially sterilize the material mass. The extruded material is forced through a die and released to an ambient environment, rapidly reducing pressure of the material and thereby lysing spores and microorganisms surviving conditions within the extruder. The emerging material is segmented and dried, or segmented and tumbled to form pellets, then dried.

  • Patent number: 5746802
    Abstract: In a method for composting organic material, the material to be composted is placed, in disintegrated form, in a container. The material to be composted is introduced into the inner, lower part of an accumulation of disintegrated material which was previously introduced into the container. The material introduced into the container is then degraded biologically in zones which, are moved upwards as additional disintegrated material is being introduced into the container. Finally composted material is withdrawn from the upper part of the accumulation of material. A device for carrying out the method has a container and a material feed unit. The material feed unit has a feed tube with an outlet end which opens centrally in the lower part of the container, a material inlet communicating with the feed tube to receive the material to be composted, and a press for pressing the material in the feed tube toward the outlet end of the feed tube.

  • Patent number: 5741344
    Abstract: A process for the conversion of organic agricultural waste into a soil amendment uses earthworms. The organic material is rent into small pieces, placed in a rick with 60% or more moisture. Earthworms are added to the rick for the consumption of the decomposing organic material. Succeeding ricks are added as the material is being consumed until the resulting castings can be most efficiently separated from the earthworms and remaining organic material. Storage as silage of the organic agricultural material may be employed between harvesting and addition of the earthworms.
